To address the problems in the related art, the present disclosure proposes a method of creating a planar mesh. Fig. 1 shows a flow diagram of a method for creating a planar grid, as shown in fig. 1, the method for creating a planar grid includes at least the following steps:

step S110, size information of the virtual object in the virtual scene is obtained, and a plurality of calculation relations of the size information are determined.

And S120, obtaining grid appearance information corresponding to the virtual object according to the size information and the plurality of calculation relations, and creating a plane grid according to the grid appearance information, wherein the plane grid is used for indicating the position of the virtual object in the virtual scene.

The steps of the method of creating a planar mesh are described in detail below.

In step S110, size information of the virtual object in the virtual scene is acquired, and a plurality of calculation relationships of the size information is determined.

In an exemplary embodiment of the present disclosure, the virtual scene refers to an environment where the virtual object is located, and the virtual scene may be a virtual scene in a game, may be a virtual scene in an animation, may be a flight scene when a flight environment is simulated, and may also be a driving scene when a vehicle is driven, which is not particularly limited in this exemplary embodiment. It is worth mentioning that the virtual scene may be any scene implemented by applying AR technology.

The virtual object refers to an object in a virtual scene, which is controlled by a user through an AR technology, and the virtual object may be a game character, an airplane, an automobile, or an object that can be controlled by any user in the virtual scene.

The size information refers to one of length information and width information of the virtual object, and for example, if the length information and the width information of the virtual object are 20 and 10, respectively, the size information refers to length information corresponding to 20.

The plurality of calculation relationships refer to a plurality of calculation relationships related to the size information.

For example, if the virtual scene is a game scene and the virtual object is a game character in the game scene, the size information of the acquired virtual object may be the width information 10 of the virtual object. A plurality of calculation relationships corresponding to the width information are acquired, and the plurality of calculation relationships include the size information 10.

In an alternative embodiment, fig. 2 shows a schematic flowchart of obtaining size information of a virtual object in a virtual scene, and as shown in fig. 2, the method at least includes the following steps: in step S210, length information and width information of the virtual object are acquired.

The virtual object can be replaced by a bounding box, the bounding box can be a cube or a cuboid, the length information refers to the length value of the bounding box, and the width information refers to the width value of the bounding box.

Wherein the bounding box is a cube with a slightly larger volume and simple characteristics, and the purpose is to approximately replace a complex collection object. For example, a slightly larger cube may be used to approximate the replacement virtual object.

Or, a cube which can replace the virtual object can be calculated by a certain algorithm, the length information refers to the length value of the cube, and the width information refers to the width value of the cube.

For example, if the bounding box of the substitute virtual object is a cuboid, the length and width of the cuboid are 20 and 10, respectively. At this time, the length information of the acquired virtual object is 20, and the width information of the acquired virtual object is 10.

In step S220, the length information and the width information are compared to obtain a length comparison result, and the size information of the virtual object is determined according to the length comparison result.

And after the length information and the width information are acquired, comparing the length information and the width information to obtain a length comparison result, and determining the size information of the virtual object according to the length comparison result.

For example, the length information of the obtained virtual object is 20, the width information of the obtained virtual object is 10, and the length comparison result is obtained by comparing the length information and the width information.

In the exemplary embodiment, the size information of the virtual object is determined through the length comparison result, which is helpful for determining the grid appearance information of the planar grid according to the size information subsequently, so that the size of the planar grid is ensured to be adapted to the virtual object, and the situation that the planar grid is smaller than the virtual object is avoided.

In an alternative embodiment, fig. 3 shows a schematic flowchart of determining a plurality of calculation relations of the size information, as shown in fig. 3, the plurality of calculation relations include a first calculation relation, a second calculation relation, and a third calculation relation, and the method at least includes the following steps: in step S310, a first calculation relationship is determined based on the size information and the first and second thresholds corresponding to the size information.

The first threshold value is a minimum value that the size information can obtain, and the second threshold value is a maximum value that the size information can obtain.

The first calculation relationship refers to one calculation expression having a relationship with the size information.

For example, the size information obtained is L_maxThe first threshold corresponding to the size information is C_minAnd the second threshold corresponding to the size information is C_maxThe first calculated relationship obtained may be formula (1).

R_cnt＝C_cnt＝count＝L_max×2+1，count∈[C_min，C_max] (1)

Wherein R is_cntLine number information for a planar grid, C_cntColumn number information of the plane grid. It should be noted that the row number information and the column number information may be equal, and the row number information and the column number information may also be unequal, which is not particularly limited in this exemplary embodiment. L is_maxAs size information, C_minIs a first threshold value, C_maxIs the second threshold.

In step S320, the rounding calculation is performed on the size information to determine a second calculation relationship.

The second calculation relationship is obtained by performing an integral calculation on the size information.

For example, the second calculated relationship may be as shown in equation (2).

d_int＝floor(L_max×0.1) (2)

Wherein d is_intFor node spacing information of a planar grid, floor () is a floor function, e.g., floor (2.1) has a value of 2 and floor (2.7) has a value of 2. L is_maxIs the size information.

In step S330, the rank information is calculated according to the first calculation relationship, and a third calculation relationship is determined by calculation according to the first threshold and the rank information.

The row and column information refers to information of the number of rows and columns of the planar grid, and the row and column information may be an odd number value or an even number value, which is not particularly limited in this exemplary embodiment.

For example, the third calculated relationship may be as shown in equation (3).

S＝(R_cnt-C_min)/4.0+1 (3)

Wherein S isArea information of mesh nodes referring to a planar mesh, R_cntLine number information for a planar grid, C_minIs a first threshold of size information of the planar mesh.

In the exemplary embodiment, the determination of the plurality of calculation relationships with the size information is helpful for obtaining the mesh appearance information of the planar mesh through the plurality of calculation relationships with the size information in the following, so that the complexity of determining the planar mesh appearance information is reduced, and the speed of creating the planar mesh is further increased.

In step S120, mesh appearance information corresponding to the virtual object is obtained according to the size information and the plurality of calculation relationships, and a planar mesh is created according to the mesh appearance information, where the planar mesh is used to indicate a position of the virtual object in the virtual scene.

In this exemplary embodiment, the planar mesh refers to a mesh indicating a position of a virtual object in a virtual scene, and specifically, the planar mesh may be regarded as being formed by a plurality of mesh nodes, each mesh node has a certain size, a certain node distance is provided between the mesh nodes, and each mesh node has a cross-shaped line with a node center as an intersection. Based on this, in order to create the planar mesh, mesh node area information, mesh node pitch information, and mesh row and column information need to be acquired.

Therefore, the mesh appearance information refers to information required for creating a planar mesh, and the mesh appearance information may be row and column information of the mesh, node area information of the mesh, or node distance information of the mesh, which is not particularly limited in this exemplary embodiment.

For example, the row and column information, the node pitch information and the node area information of the planar grid obtained according to the plurality of calculation relations are 5, 2 and 1, respectively. Based on this, a five-row five-column planar grid is created with a circular node of area 1 at each row-column intersection and with a node spacing of 2.

Fig. 4 is a schematic diagram of a specific created planar grid, as shown in fig. 4, where 410 is a grid node in the planar grid, 420 is a row in the planar grid, 430 is a column in the planar grid, and d is node spacing information in the planar grid.

In an alternative embodiment, fig. 5 shows a schematic flow chart of adjusting the second center position information, and as shown in fig. 5, the method at least includes the following steps: in step S510, first center position information corresponding to the virtual object is acquired, and second center position information corresponding to the planar mesh is acquired.

The first center position information refers to a position where a center point of a bottom surface of a bounding box representing the virtual object is located, for example, the bounding box representing the virtual object is a rectangular parallelepiped, the width information of the rectangular parallelepiped is 10, and the length information of the rectangular parallelepiped is 10.

If the lower left corner of the bottom surface of the rectangular parallelepiped is the origin, the center point position information of the bottom surface of the rectangular parallelepiped may be (5, 5).

The second center position information is the position of the center point of the planar grid, for example, the length of the planar grid is 20, the width of the planar grid is 20, the left small corner of the planar grid is used as a dot, and the second center position information is (10, 10).

It is worth mentioning that the determination of the first center position information and the second center position information must be referred to the same origin.

For example, the virtual object is at the upper right corner of the planar grid, the length information of the virtual object is 20, the width information of the virtual object is 10, the length of the planar grid is 40, the width of the planar grid is 40, and with any point in the virtual scene as a dot, the first center position information of the virtual object can be determined to be (15, 5), and based on this, the second center position information of the planar grid obtained is (10, 10).

In step S520, the second center position information is adjusted according to the first center position information and the second center position information.

And adjusting the second central position information according to the first central position information and the second central position information.

For example, when the virtual object moves, the first center position information changes, and when the distance between the second center position information and the first center position information is greater than a preset distance threshold, the second center position information is adjusted.

In this exemplary embodiment, the second center position information may be adjusted according to the first center position information and the second center position information, so that the position of the planar mesh may change in real time according to the movement of the virtual object, and an effect of prompting the position of the virtual object in the virtual scene through the planar mesh is improved.

In an alternative embodiment, fig. 6 shows a schematic flow chart of adjusting the second center position information, and as shown in fig. 6, the method at least includes the following steps: in step S610, third center position information of the virtual object is acquired, and a movement distance between the first center position information and the third center position information is calculated.

The third center position information refers to a position of a center of the bottom surface of the virtual object bounding box after a section of movement, and the movement distance refers to a distance value between the first center position information and the third center position information.

For example, if the first center position information is P_GoriThe third central position of the virtual object after moving a distance is P_McurThe distance between the first center position information and the third center position information, i.e., the movement distance, can be calculated by formula (4).

d(d_x，d_y)＝P_Mcur-P_Gori (4)

Wherein d is coordinate information of the moving distance, specifically, d_xA moving distance of the virtual object in comparison with the left and right directions, d_yIs the moving distance of the virtual object compared with the up-down direction, P_GoriFirst center position information, P, of a virtual object before movement_McurThird center position information of the moved virtual object.

In step S620, the moving distance is compared with a preset distance threshold to obtain a distance comparison result, and the second center position information is adjusted according to the distance comparison result and the second center position information.

The preset distance threshold refers to a critical value for determining whether the planar mesh needs to move, and the preset distance threshold may be half of the mesh node distance information, may also be twice of the mesh node distance information, and may also be an arbitrary value, which is not particularly limited in this exemplary embodiment.

The distance comparison result is a comparison result of the moving distance and the preset distance threshold, and obviously, there are three distance comparison results, namely, the moving distance is greater than the preset distance threshold, the moving distance is smaller than the preset distance threshold, and the moving distance is equal to the preset distance threshold.

For example, if the moving distance is 5 and the preset distance threshold is 6, it is obvious that the distance comparison result at this time is that the moving distance is smaller than the preset distance threshold, at this time, the second center position information may not be changed, that is, the position of the plane grid is unchanged.

In the exemplary embodiment, the moving distance is compared with the preset distance threshold to obtain a distance comparison result, and the second center position information is adjusted according to the distance comparison result, that is, the information of the planar mesh is changed only when the virtual object moves to a certain distance, so that the effect of prompting the position of the virtual object in the virtual scene is ensured, and the performance loss is reduced.

In an alternative embodiment, fig. 7 shows a schematic flow chart of adjusting the second center position information, and as shown in fig. 7, the method at least includes the following steps: in step S710, if the distance comparison result indicates that the moving distance is greater than the predetermined distance threshold, the second center position information is calculated to adjust the second center position information.

And when the distance comparison result is that the moving distance is greater than the preset distance threshold, calculating the second center position information to adjust the second center position information.

For example, if the moving distance is greater than the preset distance threshold, the moving distance may be first calculated according to formula (5) to obtain the number of meshes that the planar mesh needs to move.

Wherein, I_xNumber of meshes to be moved for planar meshes, d_xA moving distance of the virtual object with respect to the left-right direction, d_intFor mesh node spacing information for a planar mesh, the floor () function is a floor function.

And then adjusts the second center position information of the planar mesh according to equation (6).

C_Gcur＝C_Gori+I_x×d_int (6)

Wherein, C_GcurFor the adjusted second center position information, C_GoriFor the second center position information before adjustment, which is the same as the first center position information before movement of the virtual object, I_xNumber of meshes to be moved for planar meshes, d_intMesh node spacing information for a planar mesh.

In step S720, if the distance comparison result is that the moving distance is smaller than or equal to the predetermined distance threshold, the second center position information is maintained.

And if the distance comparison result is that the moving distance is smaller than or equal to the preset distance threshold, keeping the second center position information unchanged.

For example, the moving distance is 2, the preset distance threshold is 5, and the second center position information is (10, 10), and obviously, when the moving distance is smaller than the preset distance threshold, the second center position information is still (10, 10).

In the exemplary embodiment, different second center position information is obtained according to different distance comparison results, so that the logicality of the method is improved.

In an alternative embodiment, fig. 8 shows a schematic flow chart of adjusting the second center position information, and as shown in fig. 8, the method at least includes the following steps: in step S810, the current moving direction of the virtual object is obtained, and the distance between the first center position information and the moved first center position information is calculated to obtain the moving distance information.

The moving distance information refers to a distance between the first center position information and the moved first center position information.

For example, if the first center position information is P_GoriThe first center position of the virtual object after moving a distance is P_McurThe distance between the first center position information and the shifted first center position information, that is, the shift distance, can be calculated by formula (7).

d(d_x，d_y)＝P_Mcur-P_Gori (7)

Wherein d is coordinate information of the moving distance, specifically, d_xA moving distance of the virtual object in comparison with the left and right directions, d_yIs the moving distance of the virtual object compared with the up-down direction, P_GoriFirst center position information, P, of a virtual object before movement_McurFirst center position information of the moved virtual object.

In step S820, the movement distance information is calculated to obtain the grid movement distance of the planar grid, and the second center position information and the grid movement distance are calculated to obtain the adjusted second center position information.

And the grid moving distance is the calculated grid number of the plane grid needing to be moved.

For example, the moving distance may be calculated according to equation (8) to obtain the number of meshes that the planar mesh needs to move.

The second center position information of the planar mesh is then adjusted according to equation (9).

C_Gcur＝C_Gori+I_x×d_int (9)

In the present exemplary embodiment, the second center position information is updated by a simple calculation relationship, the complexity of updating the second center position information is reduced, and the speed of determining the position of the planar mesh is increased.

In an alternative embodiment, fig. 9 shows a flow chart of adjusting color information of a planar grid, as shown in fig. 9, the method at least includes the following steps: in step S910, a plurality of color adjustment methods corresponding to the planar mesh are acquired, and a plurality of priorities corresponding to the plurality of color adjustment methods are acquired.

The color adjustment manner refers to a manner of adjusting color information of a mesh node in a planar mesh, and the content of the adjustment may be transparency of the planar mesh node, color of the planar mesh node, or an RGB (Red Green Blue ) value of the planar mesh node, which is not particularly limited in this exemplary embodiment.

The priority refers to information corresponding to an execution order of the plurality of color adjustment modes, and specifically, when the plurality of color adjustment modes can adjust the color information of the same mesh node, a color adjustment mode with a high priority is selected as the color adjustment mode for adjusting the mesh node.

For example, there are three color adjustment modes that can adjust the mesh nodes, which are color adjustment mode a, color adjustment mode B, and color adjustment mode C. It can be obtained that the priority corresponding to the color adjustment mode a is 1, the priority corresponding to the color adjustment mode B is 2, and the priority corresponding to the color adjustment mode C is 3.

In step S920, one of the color adjustment modes is determined as a target color adjustment mode according to the priorities, and the color information of the planar mesh is updated according to the target color adjustment mode.

The target color adjustment method is one of the plurality of color adjustment methods, and the priority level corresponding to the target color adjustment method is higher than the priority level of the other color adjustment methods of the plurality of color adjustment methods.

The color information refers to information related to a color of a mesh node of the planar mesh, and the color information may be a transparency of the mesh node of the planar mesh, a color value of the mesh node of the planar mesh, or an RGB value of the mesh node of the planar mesh, which is not particularly limited in this exemplary embodiment.

For example, the color information is the transparency of the plane mesh, and there are three color adjustment modes, specifically, the adjustment mode with the highest priority is the color adjustment mode a among the multiple color adjustment modes, and at this time, the color adjustment mode a is the target color adjustment mode.

And after the target color adjusting mode is determined, adjusting the transparency of the grid nodes of the plane grid according to the target color adjusting mode.

In the present exemplary embodiment, there are a plurality of color adjustment manners that adjust the color information of the planar mesh, and the target color adjustment manner that finally adjusts the color information of the planar mesh is determined according to the priority of the color adjustment manners, increasing the flexibility in determining the color adjustment manner. In different scenes, different target color adjustment modes can be determined by changing the priority of the color adjustment modes, and the application scene of creating the planar grid is expanded.

In an alternative embodiment, fig. 10 is a schematic flow chart illustrating a process of adjusting color information of a planar grid, as shown in fig. 10, where a target color adjustment mode is a first color adjustment mode, and the method at least includes the following steps: in step S1010, position information other than the second center position information is acquired, and the second center position information and the position information are calculated to obtain a position calculation result.

The first color adjustment mode is one of a plurality of color adjustment modes.

The second central position information is the position of the central grid node in the planar grid, and the other position information refers to the position information of the other grid nodes in the planar grid except the central grid node.

The position calculation result refers to a distance value between the second center position information and other position information.

For example, if the second center position information is P_c(P_cx，P_cy) Any one of the other position information may be P_n(P_nx，P_ny) The second center position information and the other position information may be calculated according to formula (10) to obtain the position calculation result.

Where d is the position calculation result, P_cxInformation of abscissa as information of second center position, P_cyIs ordinate information of the second center position, P_nxInformation of abscissa as other position information, P_nyAnd is ordinate information of other position information.

In step S1020, a parameter range corresponding to the first color adjustment mode is determined, and a first target parameter value is determined within the parameter range according to the position calculation result.

The parameter range refers to a value range of the color information corresponding to the first color adjustment mode. The first target parameter value refers to a value of color information corresponding to other position information.

For example, fig. 11 shows the parameter range corresponding to the first color adjustment mode, as shown in fig. 11, wherein the abscissa represents the position calculation result, d_minFor the minimum in the position calculation result, d_maxThe maximum value in the position calculation results.

The ordinate represents the first target parameter value corresponding to the position calculation result, and thus it can be seen that the parameter range corresponding to the first color adjustment manner is [0.05, 0.8 ].

If d in FIG. 11_minIs 1, d_maxAt 5, the calculation relationship between the position calculation result and the first target parameter value can be determined as equation (11) from the two points (10.8), (50.05).

y＝-0.1875x+0.9875 (11)

Wherein y is a first target parameter value, x is a position calculation result, and the first target parameter value corresponding to the position calculation result can be obtained according to the formula (11). Assuming that the position calculation result is 2 at this time, the corresponding obtained first target parameter value is 0.6125.

In step S1030, the color information of the planar mesh is updated in accordance with the first target parameter value.

And updating the color information of the plane grid according to the first target parameter value.

For example, the obtained position calculation result corresponding to the other position information is 2, and the corresponding obtained first target parameter value is 0.6125. The color information is transparency information, and at this time, the transparency value of the mesh node of the planar mesh corresponding to the other position information is adjusted to 0.6125.

In the exemplary embodiment, the determined first color adjustment mode is related to the position calculation result, so that the distance between the grid node and the center point of the grid can be known according to different color information of the grid node, the effect of prompting the position of the virtual object in the virtual scene is more obvious, and the experience degree of a user is optimized.

In an alternative embodiment, fig. 12 is a schematic flow chart of adjusting color information of a planar grid, as shown in fig. 12, a target color adjustment mode is a second color adjustment mode, and the method at least includes the following steps: in step S1210, a target node is determined in the planar grid according to the current moving direction, and a color calculation relationship corresponding to the second color adjustment manner is obtained.

The second color adjustment mode is one of the color adjustment modes.

The current moving direction refers to a current moving direction of the virtual object, and the moving direction may be an angle value or may be in a text form, which is not particularly limited in this exemplary embodiment.

The target node is a grid node in the planar grid which needs to adjust the color information and is determined according to the current moving direction.

The color calculation relationship may be that the transparency of the mesh nodes is adjusted to 1 and then adjusted to 0 to achieve a flickering effect, or that the transparency of one part of the target nodes is adjusted to 1 and the transparency of the other part of the target nodes is adjusted to 0 to achieve a fade-in and fade-out effect.

For example, if the current moving direction of the virtual object is the front direction and the currently displayed grid in the planar grid is five rows and five columns, the target node acquired at this time may be a grid node on the first row in the displayed five rows and five columns.

FIG. 13 is a color calculation relationship corresponding to a second calculation relationship, as shown in FIG. 13, where t is time, a is a value of transparency, and t is a value of transparency_maxThe preset time may be any time value for the preset time, and this exemplary embodiment is not particularly limited in this respect.

For example, the created planar grid is actually a planar grid with seven rows and seven columns, but the transparency values of the grid nodes in the first row, the first column, the seventh row and the seventh column are adjusted to 0 during the display process, and the transparency values of the grid nodes in the remaining rows and columns are adjusted to 1, so that the fading effect can be realized when the planar grid moves.

If the current moving direction of the virtual object is the right front direction and the currently displayed grid in the planar grid is five rows and five columns, the target nodes acquired at this time may be a plurality of grid nodes in the first row, the seventh row, the first column and the seventh column which are not displayed.

The color adjustment manner corresponding to the second color calculation relationship may be to adjust the transparency of the grid nodes in the first row and the seventh column to 1 within a preset time, and adjust the transparency of the grid nodes in the first column and the seventh row to 0 within a preset time, so as to achieve a fade-in and fade-out effect.

In step S1220, the color information of the target node is updated within a preset time according to the color calculation relationship.

And adjusting the color information of the target node according to the color calculation relationship in the preset time.

For example, fig. 14 is an effect diagram of adjusting the color information of the target node according to the color calculation relationship shown in fig. 13, as shown in fig. 14, wherein the created planar grid is a planar grid with seven rows and seven columns, and in actual reality, the transparency of the grid nodes in the first row, the seventh row, the first column and the seventh column is adjusted to 0.

Row 1410 is the second row of the planar grid, column 1420 is the second column of the planar grid, node 1430 is the grid node in the planar grid, cuboid 1440 is the virtual object, if the current moving direction is right and left, 1450 is the column where the target node is located, 1460 is the row where the target node is located, and arrow 1470 indicates the process of showing the effect.

If t in FIG. 13_maxFor 10s, the transparency of the target node on 1460 is slowly adjusted to 1 within 0s to 5s and the transparency of the target node on 1460 is slowly adjusted to 0 within 5s to 10s according to the color calculation relationship shown in fig. 13, so that a flicker effect of transparency once is performed by the edge node in the moving direction when the virtual object moves.

For example, fig. 15 is a diagram of an effect of implementing a fade-in and fade-out of a target node according to a current direction, as shown in fig. 15, where the created planar grid is a planar grid with seven rows and seven columns, in an actual reality, transparency of grid nodes in the first row, the seventh row, the first column, and the seventh column is adjusted to be 0, 1510 is a virtual object before movement, 1520 is the planar grid before movement, 1530 is the virtual object after movement, and an arrow 1540 is a process of displaying the fade-in and fade-out effect.

Also, in fig. 15, the current moving direction is the upper right, the value of the transparency of the 3 rd to 7 th mesh nodes in the seventh row and the 1 st to 5 th mesh nodes in the seventh column is adjusted to 1 within a preset time, and the value of the transparency of the 2 nd to 6 th mesh nodes in the sixth row and the 2 nd to 6 th mesh nodes in the second column is adjusted to 0, so as to achieve an effect of fading in and out when the virtual object moves.

In the exemplary embodiment, the color information of the grid nodes is adjusted according to the second color adjustment mode, so that not only the position of the virtual object in the virtual scene can be prompted to the user, but also the current moving direction of the virtual object can be prompted to the user, and the experience degree of the user is improved.

In an alternative embodiment, fig. 16 is a schematic flow chart of adjusting color information of a planar grid, as shown in fig. 16, a target color adjustment mode is a third color adjustment mode, and the method at least includes the following steps: in step S1610, a first angle value corresponding to the current moving direction is acquired, and node position information of the planar mesh is acquired.

The first angle value refers to an angle value of an included angle between the current moving direction and a front direction in the virtual scene. The node position information indicates information of a position where the grid node is located, and the node position information may be in a two-dimensional coordinate form or a longitude and latitude form, which is not particularly limited in this exemplary embodiment.

For example, assuming that the true south direction in the virtual scene is the front direction in the virtual scene, the current moving direction of the virtual object is obtained at this time, and the angle value between the current moving direction and the true south direction in the virtual scene is the first angle value corresponding to the current moving direction.

The position information of the grid nodes is obtained, specifically, the position of the center node in the grid nodes, that is, the second center position information, may be set as the origin of coordinates, the current moving direction of the virtual object is the X-axis direction of the coordinates, the direction perpendicular to the X-axis is the Y-coordinate direction, and if the grid spacing information of the planar grid is 2, the node position information of the grid adjacent to the second center position is (2, 0), (-2, 0), (0, 2) and (0, -2), and similarly, the node position information of other planar grids is analogized.

In step S1620, a second angle value corresponding to the node position information is determined, and an angle difference value between the first angle value and the second angle value is calculated.

The second angle value refers to an angle value of a connecting line of the second center position information and the node position information compared with a front direction in the virtual scene, and the angle difference value refers to an absolute value of a difference value between the first angle and the second angle.

For example, fig. 17 is a schematic diagram of determining a first angle value and a second angle value, as shown in fig. 17, wherein an arrow 1710 is a current moving direction of a virtual object, a-Z axis is a front direction in a virtual scene, and a + X axis is a direction perpendicular to the-Z axis, so that the determined first angle value is 0 °.

If the second angle value is an angle value corresponding to a grid node in the fourth column of the second row in fig. 17, the angle a is the second angle value, and the second angle value is 45 °. Since the first angle value is 0, the angle difference and the second angle value are equal to 45 ° at this time.

In step S1630, an angle range corresponding to the third color adjustment manner is determined, and a second target parameter value corresponding to the angle range is acquired.

The third color adjustment mode is one of a plurality of color adjustment modes, and the angle range refers to a value range of an angle difference value in the third color adjustment mode. The second target parameter is a color information value corresponding to any one of the angle difference values within the angle difference value range.

For example, fig. 18 is a calculation relationship between the angle range and the second target parameter value, as shown in fig. 18, wherein the abscissa represents the angle difference value, and the ordinate represents the second target parameter value, and the specific second target parameter value may be a transparency value of a mesh node in the planar mesh.

Specifically, when the angle range is 0 ° to 30 °, the value range of the transparency of the grid node is 1 to 0.5; when the angle range is 30-90 degrees, the value range of the transparency of the grid nodes is 0.5-0.1; when the angle range is 90-150 degrees, the value range of the transparency of the grid nodes is 0.2-0; when the angle range is 150 degrees to 180 degrees, the transparency of the grid node takes a value of 0.

In step S1640, the color information of the planar mesh is updated according to the second target parameter value.

And updating the position information of the plane grid according to the obtained second target parameter value.

For example, as shown in fig. 18, if the angle difference is 30 °, the second target parameter value corresponding to the angle difference is 0.5, that is, the transparency value is 0.5, and at this time, the transparency value of the mesh node corresponding to the angle difference of 30 ° is updated to 0.5.

In the exemplary embodiment, the color information of the grid nodes is updated according to the angle difference, so that not only the position of the virtual object in the virtual scene is prompted to the user, but also the effect of prompting the current moving direction of the virtual object is increased, and the experience degree of the user is improved.

Specifically, in step 1910, size information of the virtual object is obtained, a plurality of calculation relationships corresponding to the size information are determined, appearance information of the planar mesh is obtained according to the plurality of calculation relationships based on the size information, and the planar mesh is framed according to the appearance information.

When the virtual object starts to move, the planar mesh appears, and when the distance that the virtual object moves reaches a preset distance threshold, the second center position information of the planar mesh is adjusted according to formula (12), formula (13), and formula (14).

d(d_x，d_y)＝P_Mcur-P_Gori (12)

C_Gcur＝C_Gori+I_x×d_int (14)

Where d is coordinate information of the moving distance, specifically, dx is the moving distance of the virtual object in the left-right direction, dx is the moving distance of the virtual object in the up-down direction, P_GoriInformation on the center position of the virtual object before movement, P_McurIs the center position information of the moved virtual object.

Ix is the number of grids that the planar grid needs to move, d_xA moving distance of the virtual object with respect to the left-right direction, d_intFor node spacing information of a planar grid, the floor () function is a downward integer.

Meanwhile, after the color information of the mesh node is calculated through the steps S1930, S1940, and S1950, and three pieces of color information are calculated, respectively, the priority corresponding to each color adjustment manner is acquired, the target color adjustment manner is determined according to the priority, and the corresponding color information is calculated according to the target color adjustment manner in the step S1960.

After the position of the planar mesh and the color information of the planar mesh are determined through steps S1920 and S1960, the position of the planar mesh and the color information are updated.
