For example, in a game scene.

The virtual scene is created in the game application, the virtual light source is arranged in the virtual scene, when the virtual object is displayed in the virtual scene, the influence of the irradiation of the virtual light source on the virtual object is required to be considered, the virtual object is displayed by adopting the method provided by the embodiment of the application, and the diffuse reflection effect and the reflection effect generated on the surface of the virtual object under the irradiation of the virtual light source can be considered, so that the displayed virtual object is more real, and the display effect of the virtual object is improved.

As another example, the method is applied to a virtual reality scene.

Fig. 2 is a flowchart of another virtual object display method according to an exemplary embodiment, and referring to fig. 2, the method is applied to a terminal, where the terminal is a portable, pocket-sized, hand-held, or other type of terminal, such as a mobile phone, a computer, a tablet computer, etc., and the method includes the following steps:

201. the terminal acquires object parameters of the virtual object.

In the embodiment of the disclosure, in order to make the display effect of the virtual object more natural, a map is added to the surface of the virtual object, when the map is selected, the brightness of the surface of the virtual object under the irradiation of the light source is considered, so that the map with the brightness matched with the brightness of the surface of the virtual object is selected, and the map is added to the surface of the virtual object, so that the effect of the surface of the virtual object under the irradiation of the light source is simulated, and the display effect of the virtual object is improved.

The virtual object refers to an object arranged in a virtual scene, and optionally, the virtual object is a dynamic object such as a person, an animal, a plant, or a static object such as a table, a chair, or the like. The object parameters of the virtual object are parameters required when the virtual object is displayed in the virtual scene, and according to the object parameters of the virtual object, various parameters generated by the virtual object under the irradiation of the virtual light source can be determined, wherein the various parameters are used for describing the conditions that the display effect of the virtual object under the irradiation of the virtual light source should be met. And selecting corresponding maps according to various parameters so that the display effect achieved when the selected maps are added to the surface of the virtual object meets the conditions.

In one possible implementation, since the virtual object surface includes a plurality of location points, each location point having a corresponding object parameter, the object parameters of the virtual object include a normal vector and an illumination vector at the plurality of location points. The normal vector at any position point is a vector in the normal direction of the position point, namely a vector in the direction perpendicular to the surface of the virtual object where the position point is located, and the illumination vector at any position point is a vector in the light illumination direction of the position point.

For example, referring to the schematic diagram of the position point shown in fig. 3, the position point a is a position point on the surface of the sphere, the vector N is a normal vector at the position point a, and the vector L is an illumination vector at the position point a.

202. And the terminal acquires diffuse reflection parameters and reflection parameters of the virtual object according to the normal vectors and the illumination vectors of the plurality of position points.

In the embodiment of the disclosure, since the diffuse reflection phenomenon and the reflection phenomenon are generated on the surface of the object under the irradiation of the light source, in order to make the display effect of the virtual object more realistic, the diffuse reflection parameter and the reflection parameter of the surface of the virtual object are obtained, the diffuse reflection parameter is used for describing the diffuse reflection condition that the virtual object should satisfy under the irradiation of the virtual light source, and the reflection parameter is used for describing the reflection condition that the virtual object should satisfy under the irradiation of the virtual light source, so that the virtual object is displayed according to the diffuse reflection parameter and the reflection parameter.

Since the virtual object is irradiated by the virtual light source in the virtual scene, and is also irradiated by the reflected light of other virtual objects in the virtual scene, the irradiation of the reflected light of other virtual objects affects the darker part on the surface of the virtual object, that is, the darker part on the surface of the virtual object is irradiated by the reflected light of other virtual objects, and the brightness is improved. That is, the smaller the diffuse reflection parameter generated when the virtual object is irradiated by the virtual light source, the darker the surface of the virtual object, and the larger the reflection parameter generated when the reflected light is irradiated by the reflected light of other virtual objects, the larger the influence of the reflected light on the brightness on the surface of the virtual object, so that the diffuse reflection parameter and the reflection parameter of the virtual object have a negative correlation.

That is, the diffuse reflection parameter and the reflection parameter of the virtual object are affected by the illumination intensity, the brighter the illumination intensity is, the larger the diffuse reflection parameter is, the smaller the influence of the reflected light is, and the smaller the reflection parameter is; the smaller the illumination intensity, the darker the virtual object surface, the smaller the diffuse reflection parameter, the larger the influence of reflected light, and the larger the reflection parameter.

The diffuse reflection parameters of the virtual object include diffuse reflection sub-parameters of a plurality of location points on the surface of the virtual object, and the specular reflection parameters of the virtual object include specular sub-parameters of a plurality of location points on the surface of the virtual object. Because the surface of the virtual object comprises a plurality of position points, when the diffuse reflection parameters and the reflection parameters of the virtual object are acquired, the diffuse reflection subparameter and the reflection subparameter of each position point are required to be acquired respectively, the diffuse reflection subparameters of the plurality of position points are combined to obtain the diffuse reflection parameters of the virtual object, and the reflection subparameters of the plurality of position points are combined to obtain the reflection parameters of the virtual object. For example, if the diffuse reflection parameter of the virtual object is a matrix, the diffuse reflection sub-parameter of each position point is each element in the matrix.

The embodiment of the disclosure is illustrated by taking diffuse reflection subparameters and reflection subparameters of any position points as examples.

In one possible implementation manner, since the diffuse reflection phenomenon refers to a phenomenon that light irradiates a rough object surface, and the normal direction of each position point on the object surface is inconsistent, so that the light is reflected in different directions, the terminal obtains the diffuse reflection subparameter of the position point according to the normal vector and the illumination vector of the position point.

Alternatively, the terminal uses (0, 1) to represent the brightness of the position point on the virtual object surface, 0 represents the brightest, and 1 represents the darkest. Since the dot product of the two vectors is less than 0, the terminal determines the dot product of the normal vector and the illumination vector as a first value, and determines the larger value of the first value and 0 as the diffuse reflection subparameter of the position point. That is, if the dot product is less than 0, 0 is taken as the diffuse reflection subparameter, and if the dot product is not less than 0, the first numerical value is taken as the diffuse reflection subparameter.

For example, the following formula is used to obtain the diffuse reflection subparameter of the location point:

D＝max(0，dot(N，L))；

Wherein D represents the diffuse reflection subparameter of the position point, N represents the normal vector of the position point, L represents the illumination vector of the position point, and dot (N, L) represents the dot product of N and L.

Since the brightness of the surface of the virtual object is affected not only by the virtual light source but also by the reflected light of other virtual objects, the terminal also needs to acquire the reflection sub-parameters of each position point.

In one possible implementation manner, the terminal performs inverse processing on the diffuse reflection subparameter to obtain a first reflection subparameter of the position point, and adjusts the first reflection subparameter according to a preset first adjustment parameter to obtain a second reflection subparameter of the position point, wherein the second reflection subparameter represents the brightness of the position point when the position point is irradiated by reflected light of other virtual objects.

The diffuse reflection sub-parameter is subjected to a negation process to determine the influence of the reflected light of other virtual objects on the brightness of the position point when the position point is irradiated with the reflected light. Alternatively, 1 represents brightest and 0 represents darkest, and the negation is to subtract 1 from the diffuse reflectance subparameter. For example, if the diffuse reflection subparameter of the location point is 0, the brightness of the location point is the lowest, i.e. the darkest, then the inverse processing is performed on 0, so as to obtain the first reflection subparameter 1, which indicates that the brightness of the location point is increased more when the location point is irradiated by the reflected light of other virtual objects.

If the first reflection sub-parameter obtained by the reflection processing is taken as the reflection sub-parameter of the position point, the value obtained after the addition of the diffuse reflection sub-parameter and the reflection sub-parameter is 0, and the position point has no reflection effect on light, so that the first reflection sub-parameter is adjusted according to the first adjustment parameter to obtain the adjusted second reflection sub-parameter, and the brightness of the position point is accurately reflected by adopting the parameter obtained after the addition of the diffuse reflection sub-parameter and the adjusted second reflection sub-parameter. The first adjustment parameter is used for indicating the influence degree of the reflected light on the virtual object, and is set according to the intensity of the reflected light of other virtual objects, if the reflected light of other virtual objects is strong, that is, the influence of the reflected light of other virtual objects on the virtual object is large, the first adjustment parameter is a large parameter, and if the reflected light of other virtual objects is weak, that is, the influence of the reflected light of other virtual objects on the virtual object is small, the first adjustment parameter is a small parameter, and the first adjustment parameter is more than 0 and less than 1.

For example, referring to the virtual object shown in fig. 4, in the case where the virtual light source is located at the upper right side, the virtual object of the left diagram in fig. 4 is illuminated by the virtual light source, the right side is brighter, and the lower left corner is darker, but the illumination of the reflected light of other virtual objects produces the brightness in the virtual object opposite to the brightness produced by the illumination of the virtual light source, as in the virtual object of the right diagram in fig. 4, the right side is darker, and the lower left corner is brighter.

203. And the terminal determines a target map matched with the diffuse reflection parameter and the reflection parameter.

In the embodiment of the disclosure, since the terminal needs to add the map on the surface of the virtual object when displaying the virtual object, the virtual object seen by the user is the virtual object after the map is added. However, the selection of the map has a great influence on the display effect of the virtual object, for example, a certain position point of the virtual object is not irradiated by light, and then the position point is darker, the required map should be a darker map, if the display effect of the position point is inconsistent with the actual situation due to the brighter map, the display effect is poor. Because the diffuse reflection parameter and the reflection parameter are used for representing the brightness of the surface of the virtual object, the matched target mapping is determined according to the diffuse reflection parameter and the reflection parameter, so that the target mapping is added to the surface of the virtual object to display a good display effect.

In one possible implementation manner, before determining the target map matched with the diffuse reflection parameter and the reflection parameter, the terminal needs to acquire a plurality of alternative maps, and as the brightness of different parts of the virtual object is different under the irradiation of the virtual light source when the virtual object is displayed, the brightness of the plurality of alternative maps is also different, so that the plurality of alternative maps can meet the requirements of different brightness displayed by the virtual object.

And after the plurality of alternative maps are sequentially ordered from big to small according to brightness, determining the serial number of each alternative map, wherein the serial numbers of the alternative maps represent the brightness of the alternative maps, the serial numbers of different alternative maps are different, namely the brightness of different alternative maps is different, the smaller the serial number is, the brighter the brightness of the alternative map is, and the larger the serial number is, the darker the brightness of the alternative map is. The target map is any one of the multiple alternative maps or a map obtained by fusing the multiple alternative maps.

The embodiment of the disclosure is to obtain a map capable of reflecting the brightness of a position point on the surface of a virtual object according to the brightness of the position point, so that the display effect of the virtual object is consistent with the actual display effect after the map is added to the virtual object.

In one possible implementation, if the sketch image is formed by lines, and if the sketch effect is to be displayed in the image of the virtual object, the obtained alternative mapping is a line graph, the more sparse the distribution of the lines in the alternative mapping is, the brighter the alternative mapping is, the more compact the distribution of the lines in the alternative mapping is, and the darker the alternative mapping is. For example, referring to the alternative maps shown in fig. 5, the brightness of the 6 alternative maps decreases sequentially from left to right, with the first alternative map numbered 0, the second alternative map numbered 1, and the last alternative map numbered 5.

In addition, the more the number of alternative maps, the finer the division of brightness, and the more the alternative maps can be selected by the terminal, the better the display effect.

In another possible implementation, if the virtual object displays an effect other than a sketch effect, a corresponding type of map is obtained from the other effect. For example, to simulate the effect of a lattice, the alternative map is composed of a plurality of points.

In one possible implementation, the determining, by the terminal, a target map that matches the diffuse reflection parameter and the reflection parameter includes: the terminal obtains the brightness subparameter of each position point according to the diffuse reflection subparameter and the reflection subparameter of each position point; respectively acquiring weights of a plurality of alternative maps according to the brightness subparameter of each position point and the serial numbers of the plurality of alternative maps; and determining the target map according to the weights of the multiple alternative maps corresponding to each position point.

When determining the target mapping of the virtual object, since the virtual object includes a plurality of position points and the illumination received by each position point is different, that is, the brightness of each position point is different, in order to make the target mapping of the virtual object more conform to the actual illumination, the target mapping corresponding to each position point needs to be determined respectively, and the target mapping corresponding to each position point is combined together to obtain the target mapping of the virtual object.

The diffuse reflection subparameter and the reflection subparameter are used for reflecting the brightness corresponding to the position point, if the brightness subparameter is obtained only according to the diffuse reflection subparameter, the reflection effect of the virtual object cannot be reflected in the displayed virtual object, so that the displayed virtual object is inconsistent with the actual situation, the display effect is poor, and the brightness subparameter of the position point is obtained according to the diffuse reflection subparameter and the reflection subparameter, so that the obtained brightness subparameter can reflect the brightness of the position point more accurately.

In one possible implementation manner, the terminal obtains the luminance subparameter of each location point according to the diffuse reflection subparameter and the reflection subparameter of each location point, respectively, including: for each position point, the terminal adds the diffuse reflection subparameter and the reflection subparameter of the position point to obtain a first brightness subparameter of the position point; multiplying the first brightness subparameter by the number of the alternative maps to obtain a second brightness subparameter of the position point, and taking the second brightness subparameter as the brightness subparameter of the position point.

In one possible implementation manner, the terminal obtains weights of the multiple alternative maps according to the luminance subparameter of each position point and the serial numbers of the multiple alternative maps, respectively, including: for each position point, the terminal determines the matching parameter of each alternative mapping according to the difference value between the brightness subparameter of the position point and the serial number of each alternative mapping; the difference between the matching parameters of any two adjacent alternative maps is taken as the weight of the first alternative map in the any two alternative maps, and the matching parameter of the last alternative map is taken as the weight of the last alternative map. The matching parameters represent the matching degree between the brightness of the alternative mapping and the brightness of the position point, and any two adjacent alternative mapping refers to two adjacent alternative mapping in a plurality of alternative mapping which are sequentially arranged according to brightness.

If the sequence number of the alternative mapping is smaller, the difference between the brightness subparameter and the sequence number of the alternative mapping is larger, and if the sequence number of the alternative mapping is smaller, the difference between the brightness subparameter and the sequence number of the alternative mapping is smaller, and the value range of the matching parameter is fixed, so that the first reference value is used as the matching parameter of the alternative mapping in response to the difference being larger than the first reference data; responding to the difference value being smaller than the second reference value, and taking the second reference value as a matching parameter of the alternative mapping; and responding to the difference value not larger than the first reference value and not smaller than the second reference value, and taking the difference value as a matching parameter of the alternative mapping. Wherein the first reference value is greater than the second reference value.

For example, there are 6 alternative maps, the serial numbers of the six alternative maps from light to dark are sequentially 0,1, 2, 3, 4 and 5, the diffuse reflection subparameter and the reflection subparameter are added to be 0.75, the brightness subparameter is 4.5, the difference between the brightness subparameter and the serial numbers of the six alternative maps is sequentially 4.5, 3.5, 2.5, 1.5, 0.5 and-0.5, the first reference value is 1, the second reference value is 0, and the matching parameters for obtaining the six alternative maps are sequentially 1, 0.5 and 0, so that the weights for obtaining the six alternative maps are sequentially 0, 0.5 and 0.

In another possible implementation manner, if each candidate image is stored separately, each candidate image occupies one storage space, and in total, needs to occupy an enlarged storage space, then the multiple candidate images are fused, so as to reduce the number of images to be stored and save the storage space. Therefore, the terminal fuses the candidate maps with adjacent sequence numbers according to the sequence numbers of the plurality of candidate maps to obtain at least one fused map. At least one channel of the red channel, the green channel or the blue channel of the fusion map corresponds to one alternative map, and the alternative maps with adjacent serial numbers refer to two or three alternative maps with adjacent serial numbers.

For example, referring to fig. 5, there are six alternative maps with serial numbers of 0, 1, 2, 3, 4 and 5, three alternative maps with adjacent serial numbers are fused, referring to fig. 6, the alternative maps with serial numbers of 0, 1 and 2 are fused to obtain a fusion map on the left of fig. 6, the red channel of the fusion map corresponds to the alternative map with serial number of 0, the green channel corresponds to the alternative map with serial number of 1, the blue channel corresponds to the alternative map with serial number of 2, and the alternative maps with serial numbers of 3, 4 and 5 are fused to obtain a fusion map on the right of fig. 6, the red channel of the fusion map corresponds to the alternative map with serial number of 3, the green channel corresponds to the alternative map with serial number of 4, and the blue channel corresponds to the alternative map with serial number of 5.

Then, the terminal determines a matching parameter of each alternative map according to the difference between the luminance subparameter of the position point and the serial number of each alternative map, including: the terminal obtains a sequence number matrix of each fusion map; acquiring a brightness sub-parameter matrix; and obtaining the difference between the brightness sub-parameter matrix and the sequence number matrix of each fusion map, and determining a matching parameter matrix. The sequence number matrix of the fusion map comprises a sequence number of each alternative map in the fusion map.

For example, the fusion map includes three alternative maps, and the sequence number of each alternative map is 0,1 and 2 in sequence, and then the sequence number matrix is (0, 1 and 2); the luminance subparameter matrix comprises a plurality of luminance subparameters, and the number of the plurality of luminance subparameters is equal to the number of the alternative maps contained in the fusion map, for example, the luminance subparameter is 4.5, and the fusion map comprises three alternative maps, and the luminance subparameter matrix is (4.5,4.5,4.5); the matching parameter matrix includes the matching parameters of each candidate map, for example, the difference between the luminance subparameter matrix (4.5,4.5,4.5) and the sequence number matrix (0, 1, 2) is (4.5,3.5,2.5), and the matching parameter matrix is (1, 1).

After obtaining the matching parameter matrix corresponding to each fusion map, the terminal uses the difference value between the matching parameters of any two adjacent alternative maps as the weight of the first alternative map in the two alternative maps, and uses the matching parameter of the last alternative map as the weight of the last alternative map.

For example, the weight of each alternative map is obtained using the following formula:

weights＝saturate((intensity*m)-(a1，a2，a3))；

Wherein weights denotes a matching parameter matrix of the fusion map, intensity denotes a luminance subparameter of the position point, m denotes the number of alternative maps, a denotes the number of alternative maps, saturate (·) denotes that each obtained matching parameter is limited between 0 and 1, i.e. if intensity m-a1 is larger than 1, the result of intensity m-a1 is 1, and if intensity m-a1 is smaller than 0, the result of intensity m-a1 is 0.

In the process of determining the matching parameter matrix by adopting the brightness sub-parameter matrix and the sequence number matrix, the matching parameters of two or three alternative maps can be obtained by one calculation, and compared with the matching parameters of each alternative map respectively calculated, the calculation amount is reduced, and the weight acquisition speed is improved.

In addition, when fusing a plurality of alternative maps, if the number of the alternative maps is a multiple of 3, fusing the adjacent three alternative maps into one fusion map; if the number of the alternative maps is not a multiple of 3 and one alternative map is left, directly taking the remaining one alternative map as a fusion map; if the number of alternative maps is not a multiple of 3 and two alternative maps remain, the remaining two alternative maps are fused.

In one possible implementation manner, the determining, by the terminal, the target map according to the weight corresponding to each candidate map includes: the terminal takes the candidate mapping corresponding to the maximum weight as a target mapping; or the terminal performs weighted fusion on the multiple candidate maps according to the weight of each candidate map, and takes the fused map as a target map.

204. And the terminal acquires highlight parameters of the virtual object according to the normal vectors, the illumination vectors and the view angle vectors of the plurality of position points.

Optionally, the object parameters further comprise a perspective vector, the perspective vector of the location point being a vector in a direction of the virtual camera relative to the location point. Setting a virtual camera in the virtual scene, wherein the picture obtained by shooting the scene where the virtual object is located by the virtual camera is the picture which is displayed by the terminal and comprises the virtual object. After the virtual light source irradiates the position point on the surface of the virtual object, if the position point directly reflects the light to the position where the virtual camera is located, the virtual camera directly shoots the position point, and then the position point is the brightest position point.

For example, referring to the schematic view of the location point shown in fig. 3, the vector H is the view angle vector at the location point a.

The embodiments of the present disclosure will be described by taking a high photon parameter obtained from a location point as an example. The highlight parameter characterizes the brightest location point on the surface of the virtual object. Therefore, the highlight parameters of the virtual object are obtained according to the normal vector, the illumination vector and the view angle vector of the position point.

In one possible implementation, the terminal uses a dot product of a sum vector of a view angle vector and an illumination vector of the position point and a normal vector of the position point as a second numerical value; taking the product of the larger value of the second value sum 0 and the illumination vector as a first high-photon parameter; and adjusting the first high-photon parameter according to a preset second adjustment parameter to obtain a second high-photon parameter, and taking the second high-photon parameter as the high-photon parameter of the position point. The sum vector is a half-angle vector obtained by adding the view angle vector and the illumination vector.

When the high photon parameter is larger than a certain reference value, the position point corresponding to the high photon parameter is the brightest position point, and the position point is brightest when the virtual object is present later; when the high photon parameter is smaller than a certain preset parameter, the position point corresponding to the high photon parameter is not the brightest position point, and then the virtual object is displayed according to the target map of the position point. For example, referring to the virtual object shown in fig. 7, the upper left corner of the virtual object is a white area, which is the brightest area in the virtual object, and includes a plurality of position points indicated by highlight parameters.

The second adjustment parameter is any value greater than 0 and less than 1, for example, 0.1, 0.2, etc. The smaller the second adjustment parameter is, the smaller the obtained high photon parameter is, and correspondingly, the smaller the high light range displayed in the virtual object is; the larger the second adjustment parameter is, the larger the obtained high photon parameter is, and accordingly, the larger the high light range displayed in the virtual object is.

For example, the high photon parameters of a location point are obtained with reference to the following formula:

G＝I*max(0，dot(N，H))；

Wherein G represents a specular parameter, I represents a viewing angle vector, N represents a normal vector, H represents an illumination vector, and dot (N, H) represents a dot product of N and H.

205. And adding a target map on the surface of the virtual object by the terminal, and displaying the virtual object with the target map added according to the highlight parameters.

In the embodiment of the disclosure, after determining the target map of each position point, the terminal adds a corresponding target map to each position point on the surface of the virtual object, and displays the virtual object with the target map added, where the target map reflects the brightness of each position point on the surface of the virtual object, and the virtual object seen by the user is more in line with the real object. Optionally, the target maps of any two location points are the same or different.

After the terminal acquires the highlight parameters of the virtual object, a highlight effect is added in the displayed virtual object, so that the position indicated by the highlight parameters of the virtual object is brightest, and a user can see the highlight part in the virtual object.

Taking a sketch image as an example, referring to a sketch image of a hand drawing shown in fig. 8, objects drawn in the sketch image have light reflection and high light, and the embodiment of the disclosure is to make a virtual object simulate the display effect of the sketch image. Referring to the virtual object shown in the left diagram of fig. 9, the added map of the surface of the virtual object is determined only according to the diffuse reflection parameter, and although the virtual object simulates the display effect of the sketch image to a certain extent, it can be clearly seen that there is no reflection and no high light in the virtual object. Referring to the virtual object shown in the right graph in fig. 9, the attached map on the surface of the virtual object is determined according to the diffuse reflection parameter and the reflection parameter, compared with the virtual object in the left graph, the lower left corner of the virtual object in the left graph can obviously show that reflection exists, the upper right corner of the virtual object in the right side has obvious highlight, and the virtual object in the right side simulates the display effect of the sketch image.

In addition, in one possible implementation manner, the virtual object is subjected to edge tracing, that is, each position point extends along the corresponding normal direction by a preset distance, an extension area is formed outside the surface of the virtual object, the extension area is the edge displayed outside the surface of the virtual object, the reference color is filled into the extension area, and the filled reference color is the color outside the surface when the virtual object is displayed. When the terminal displays the virtual object, adding a target map on the surface of the virtual object, and displaying the virtual object added with the target map and an extension area outside the surface of the virtual object, thereby realizing the display effect of extending the virtual object outwards.

In one possible implementation manner, after acquiring the highlight parameters and the extension areas of the virtual object, the terminal adds a target map to the surface of the virtual object, displays the extension areas outside the surface of the virtual object, and displays the virtual object and the extension areas outside the surface of the virtual object after adding the target map according to the highlight parameters.

In addition, for the virtual object presenting the sketching effect, in order to enable the three-dimensional virtual object in the virtual scene to display the two-dimensional sketching effect, the maps with different brightness are added on the surface of the three-dimensional virtual object, so that the three-dimensional virtual object with the maps added displays the two-dimensional sketching effect, a user can rotate the three-dimensional virtual object, view the virtual object from multiple angles, and the drawing of the two-dimensional virtual object from multiple angles is avoided.

It should be noted that, in the embodiment of the present disclosure, only the target maps corresponding to each location point are obtained according to the object parameters of the location point, and the target maps of a plurality of location points are added to the virtual object surface, respectively.

In addition, in the embodiment of the disclosure, the viewing angle vectors of a plurality of position points on the surface of the virtual object are also obtained, and then the highlight parameters of the virtual object are obtained according to the normal vectors, the illumination vectors and the viewing angle vectors of the plurality of position points.

In addition, in the embodiment of the disclosure, a first adjustment parameter is set to adjust the reflective sub-parameter of each position point, a second adjustment parameter is set to adjust the high-photon parameter of each position point, and because the first adjustment parameter and the second adjustment parameter are set by a technician, the sizes of the first adjustment parameter and the second adjustment parameter can be adjusted, so that the reflective sub-parameter and the high-photon parameter can be flexibly adjusted, the flexibility is improved, the brightness of the virtual object can be more conveniently adjusted, and the display effect is adjusted.

In addition, in the embodiment of the disclosure, the alternative maps with adjacent serial numbers are fused to obtain the fusion map, each alternative map is not required to be stored separately, and the fusion map is stored directly, so that the number of the alternative maps required to be stored is reduced, the storage space is saved, and the operation efficiency of the equipment is improved.

In addition, in the process of determining the matching parameter matrix by adopting the brightness sub-parameter matrix and the sequence number matrix, the matching parameters of two or three alternative maps can be obtained by one calculation, and compared with the matching parameters of each alternative map respectively calculated, the calculation amount is reduced, and the weight acquisition speed is improved.
