An embodiment of the present invention provides a method for editing an object in virtual reality, which is applied to a virtual reality VR system, please refer to fig. 1, where fig. 1 is a schematic diagram of the VR system, the VR system includes a display device 101, an input device 102, and a processing device 103, and both the input device 102 and the display device 101 are connected to the processing device 103. In one application scenario, the processing device 103 may be a computer, a mobile phone, a palm computer, or the like. The display device 101 may be a VR head-mounted display (virtual reality head-mounted display device). And can be used as VR glasses, VR helmets, etc. The VR head display is a device which utilizes a head-mounted display to seal the vision and the hearing of people to the outside and guide a user to generate the feeling of being in a virtual environment. The input device 102 is a device capable of mapping real world environment data to a virtual world, and is a device for inputting a user command to the VR system, and may be a sensing glove, a sensing handle, or the like.

The embodiment of the invention provides a method for editing a virtual object in a VR system. The input device detects an operation of selecting an object, for example, an object in the VR, which may be a bed, a box, a table, etc. in the VR, is selected by the input device; the input equipment detects the operation of a selection object input by a user to generate corresponding operation data, then the input equipment transmits the operation data to the processing equipment, and the processing equipment determines a target object to be edited according to the operation data; the processing equipment calculates the space editing area of the target object and determines a target adsorption plane of the target object in the space editing area; when the position of the input equipment in the actual environment changes, the input equipment detects the operation of the moving object, the input equipment transmits the data of the moving operation to the processing equipment, the processing equipment generates rays according to the received data of the operation of the moving object, the data of the rays are sent to the display equipment, and the display equipment displays the rays; the processing equipment determines the target position of the target object according to the intersection point of the ray and the target adsorption plane and moves the target object to the target position; the display device displays that the target object moves to the target position.

For convenience of understanding, words involved in the embodiments of the present invention are explained first.

Adsorption plane: according to the plane on which the objects should be placed according to the respective attributes in the real scene, the adsorption plane can be preset according to the attributes of the objects. For example, a bed or a table is placed on the ground, a wall painting is placed on the wall, and a ceiling lamp is attached to the ceiling.

In a virtual scene, the form of X, Y, Z plus signs may be used to represent six faces of an editable area, where the editable area may be understood as a rectangular solid area, and all six faces of the editable rectangular solid area may be used as adsorption planes, please understand the adsorption planes in conjunction with fig. 2 and table 1 below, and fig. 2 is a schematic diagram of the adsorption planes:

TABLE 1

An object, also understood as an object in a virtual space, may have N suction planes, where N is a positive integer greater than or equal to 1, and different objects may have different numbers of suction planes. As shown in table 1 above, the attribute of the bed or the table is an adsorption floor, the adsorption plane corresponding to the adsorption floor is a (-Z) plane, the attribute of the ceiling lamp is an adsorption ceiling, the adsorption plane corresponding to the adsorption ceiling is a (+ Z) plane, the attribute of the mural is an adsorption wall, and the adsorption plane corresponding to the adsorption wall may be one of (+ X), (-X), (+ Y) and (-Y) planes, that is, the attribute of the object has a corresponding relationship with the adsorption plane, and if the attribute of the object is determined, the attribute of the object can be determined according to the attribute and the corresponding relationship. As can be seen from the example in table 1 above, the mural may correspond to 4 adsorption planes, when the adsorption plane corresponding to an object is greater than 1, a preset adsorption plane of the object may be preset, and when the user does not rotate the object, the adsorption plane of the object is the preset adsorption plane. For example, the preset suction plane corresponding to the ceiling lamp may be set to be (-X), and if the ceiling lamp is rotated by 90 degrees around the Y axis, the suction plane corresponding to the ceiling lamp is set to be (+ Y).

It should be noted that, in table 1, the 6 adsorption planes are represented by the form of plus or minus signs X, Y, Z, which are only illustrative and do not limit the embodiments of the present invention. For example, A, B, C, D, E, F may be used to indicate different absorption planes, as long as different planes of the editing area can be distinguished, and the forms are various, which are not exhaustive here.

Referring to fig. 3, an embodiment of the present invention provides an embodiment of a method for editing an object in virtual reality, where the embodiment is described with a processing device as an execution subject, and a specific flow of steps includes:

step 301, the processing device receives an operation of selecting an object detected by the input device.

The input device detects an operation of a selection object input by a user, the input device transmits data of the operation of the selection object to the processing device, and the processing device receives the operation of the selection object detected by the input device.

As can be understood in conjunction with fig. 4, fig. 4 is a schematic view of a scene displayed in the display device. In one application scenario, a display device displays objects included in a menu, a user sees objects in the menu in the display device, for example, objects in the menu include beds, glasses, tables, wall paintings and the like, the user operates an input device (such as a sensing handle), a processing device receives an operation of a selection object detected by the input device, a ray is generated according to the operation of the selection object, and the display device displays the ray.

Step 302, the processing device determines a target object to be edited according to the operation of selecting the object.

In the virtual environment, the ray selects a target object, e.g., the ray points to a "bed", the target object is a "bed", and when the processing device determines the target object, the VR system enters an editing mode for the target object.

Step 303, the processing device calculates a spatial editing region according to the target object, and the spatial editing region is divided into a plurality of grid regions.

After the processing device determines the target object, the processing device calculates a spatial editing region of the target object. Please refer to fig. 5 and fig. 6, in which fig. 5 is a schematic diagram of a spatial editing area, and fig. 6 is a schematic diagram of a scene. In an application scenario, a cuboid can be set as the space editing area, and then the length, the width and the height of the cuboid are equally divided to form a grid structure in a three-dimensional space, wherein the side length of each equally divided grid of the grid can be 0.5 m. It should be noted that the size of the grid in the spatial editing area is illustrated herein for convenience only and is not meant to limit the invention.

It should be noted that step 303 is an optional step, and is not performed every time the target object is edited, and this step is performed once in the initialization process, and may not be performed in the subsequent editing process after the initialization is completed, that is, after the spatial editing area of the target object has been calculated.

Step 304, the processing device determines a target adsorption plane of the target object in the space editing area.

Moving the target object and placing it in the proper position requires determining the target's suction plane, it being understood that the "bed" needs to be placed on the floor and not on the ceiling, and the "ceiling lamp" needs to be placed on the ceiling and not on the wall, thus requiring determining the suction plane of the target object space editing area.

The processing equipment determines the attribute of the target object, and then determines the target adsorption plane of the target object according to the corresponding relation between the attribute and the adsorption plane.

The target adsorption plane is a preset adsorption plane, and it can be understood that the number of the adsorption planes corresponding to the target object is at least one.

In one case, the adsorption plane of the target object has only one, for example, when the target object is a "bed", the "bed" has only one adsorption plane (-Z) plane, which is a preset adsorption plane.

In another case, the target object has at least two adsorption planes. For example, when the target object is a "mural", since there are 4 suction planes of the "mural", which may be a (+ X) plane, a (-X) plane, a (+ Y) plane or a (-Y) plane, the preset suction plane of the "mural" is preset to be the (+ X) plane, that is, after the target object is selected, if the user does not rotate the "mural", the target suction plane of the target object is the preset suction plane.

In another case, the number of the adsorption planes corresponding to the target object is at least two, the target adsorption plane is an adsorption plane after the target object rotates, and an angle of each rotation of the target object may be set to 90 degrees. Firstly, the processing device determines a preset adsorption plane according to the attributes of the target object and the corresponding relation between the attributes and the adsorption plane, if the processing device determines that the preset adsorption plane of the wall painting is a (+ X) plane, the processing device receives the operation of the rotating object detected by the input device, and then the processing device determines the target adsorption plane corresponding to the target object after the target object rotates on the basis of the preset adsorption plane according to the operation of the rotating object. For example, the input device detects an operation of rotating a "mural" input by a user, the "mural" is correspondingly rotated by 90 degrees around the Y-axis, and after the "mural" is rotated, the corresponding target adsorption plane is a (-Y) plane.

Step 305, the processing device receives an operation of the moving object detected by the input device.

The user performs an operation of moving the object, for example, the user holds an input device (e.g., a handle), changes the position of the handle in the actual environment, the input device detects the operation of moving the object, generates data of the operation of moving the object, and then transmits the data of the operation to the processing device, and the processing device receives the operation of moving the object detected by the input device.

Step 306, the processing device generates rays according to the operation of the moving object and displays the rays through the display device.

The processing device generates a ray according to the operation of the moving object and then displays the ray through the display device, that is, the display device displays the current virtual scene while displaying the ray, and the user sees one ray through the display device.

In one application scenario, a user is in a real space, e.g., a room, wears a VR headset, holds a sensing handle, points the sensing handle to the floor of the real room, points rays in the VR headset to the floor of the virtual space, points the sensing handle to the ceiling of the real room, and points rays in the VR headset to the ceiling of the virtual space.

And 307, determining the target position of the target object according to the intersection point of the ray and the target adsorption plane by the processing equipment.

The target position is a position where the user wishes to place the target object in the virtual space displayed by the display device.

For the operation situation of the user, there may be two cases:

1. as will be understood in conjunction with fig. 7, fig. 7 is a schematic side view of a scene from which intersections are determined. The user operates correctly, the virtual device points to the target adsorption plane, the ray has an intersection point with the target adsorption plane, for example, the target adsorption plane of the 'bed' is a (-Z) plane, the user operates through the input device, the ray points to the ground (-Z) plane, and the intersection point of the ray a and the (-Z) plane is o.

2. As will be understood in conjunction with fig. 8, fig. 8 is a schematic diagram of a side view scene for determining intersection points. The user operation is not accurate, the virtual device is not pointed to the target adsorption plane, the ray does not intersect with the target adsorption plane, for example, the ray is pointed to the ceiling (+ Z) plane, that is, in this case, the ray does not intersect with the target adsorption plane, the ray can be mirrored, as shown in fig. 8, the mirrored ray of the ray b is c, and the intersection of the mirrored ray c is d.

In a first possible implementation manner, the processing device determines an intersection point of the ray and the target adsorption plane, and the processing device determines the intersection point as a target position, where the target object is placed.

In a second possible implementation manner, the processing device determines an intersection point of the ray and the target adsorption plane, and in the present embodiment, the case shown in fig. 7 is taken as an example for explanation. Then, the processing device calculates the center position of the grid where the intersection point is located, please understand with reference to fig. 9, where fig. 9 is a schematic diagram of the center position of the grid where the intersection point is located. The grid where the grid intersection point o is located is denoted by g, the center position of the grid g on the target adsorption plane is denoted by f, and the center position of the grid where the intersection point is located is a point f.

Then, the processing device calculates a target position of the target object according to the center position of the grid and the offset vector, wherein the target position of the target object is calculated by the following formula 1:

p _ center is P _ exp + V _ offset, where P _ center is the target position, V _ offset is the offset vector, and P _ exp is the center position of grid g.

The offset vector is a vector from a central point on a side surface corresponding to the target adsorption plane on the target grid to a preset point on the target object, and the target grid is a minimum grid area of a bounding box for accommodating the target object. Please refer to fig. 10 for understanding the offset vector in the embodiment of the present invention, wherein fig. 10 is a schematic diagram of the offset vector.

The offset vector can be calculated in two ways:

1. the pre-calculation mode is as follows: before this step 307, the method for specifically calculating the offset vector includes:

step i: the processing device determines N adsorption planes for each object according to the property of each object, where N is a positive integer greater than or equal to 1, for example, in one scenario, the menu of items includes a plurality of objects, such as beds, tables, murals, ceiling lamps, etc., and the processing device determines N adsorption planes for each object according to the property of each object, for example, the adsorption plane of a bed is a (-Z) plane, the adsorption plane of a table is a (-Z) plane, the adsorption plane of a mural can be a (+ X) plane, a (-X) plane, a (+ Y) plane, or a (-Y) plane, and the adsorption plane of a ceiling lamp is a (+ X) plane. It should be noted that the plurality of objects in the present embodiment are examples for convenience of description, and do not limit the present invention.

Step j: the processing device calculates a bounding box for each of a plurality of objects to be selected.

Please be understood in conjunction with fig. 10, fig. 10 is a schematic diagram of a bounding box. The bounding box 1002 is the smallest rectangular parallelepiped spatial region that houses the object 1001.

The processing equipment calculates the bounding box of the bed, the bounding box of the wall painting, the bounding box of the desk and the bounding box of the ceiling lamp.

Step k: the processing device calculates a target grid from the bounding box, the target grid 1101 being the smallest grid area that accommodates the bounding box 1002.

Please refer to fig. 11, wherein fig. 11 is a schematic side view of the target grid. The processing device calculates a target mesh for each of a plurality of objects.

Step l: the processing device determines a side of the target mesh corresponding to each of the N adsorption planes of each object.

As will be understood from fig. 11, the "bed" has one adsorption plane, the adsorption plane of the "bed" is a (-Z) plane, and in the target grid 1101, a side surface 11011 corresponding to the (-Z) plane is a bottom surface.

In this embodiment, a "bed" among a plurality of subjects will be described as an example, and other subjects can be understood with reference to the "bed".

Step m: the processing device calculates an offset vector, which is a vector of the center point of the side of the target mesh to a preset point on the object.

Please refer to fig. 12, which is a side view of the offset vector in fig. 12. The offset vector is a vector 1203 from a center point 1201 of a side surface (e.g., bottom surface) of the target grid to a preset point 1202 on the object when the target surface of the bounding box of the object is aligned with the side surface of the target grid.

In this embodiment of the present invention, the preset point may be any preset point on the object, and the preset point may be a central point of the object.

Offset vectors corresponding to a plurality of objects are calculated in advance, and then, an offset vector corresponding to a target object is selected from the offset vectors corresponding to the plurality of objects.

2. The real-time calculation mode is as follows:

in a second possible implementation manner, the offset vectors of all objects do not need to be calculated before step 307, but in this step, the offset vector of the target object is directly calculated, and the specific method is as follows:

step o: the processing device determines a target adsorption plane of the target object based on the properties of the target object, e.g., in one scenario, the target object is a bed, and the processing device determines the adsorption plane of the "bed" to be a (-Z) plane.

Step p: the processing device calculates a bounding box for each of the target objects.

Step q: the processing device calculates a target mesh from the bounding box of the target object.

Step r: the processing device determines a side of the target grid corresponding to the target adsorption plane of the target object.

Step m: the processing device calculates an offset vector corresponding to the target object, wherein the offset vector is a vector from a central point of the side surface of the target grid to a preset point on the object.

And 308, moving the target object to the target position by the processing device and displaying the target object through the display device.

In a first implementation manner, please understand with reference to fig. 13, fig. 13 is a schematic view of a scene in which a target object moves to a target position.

The processing device calculates a bounding box 1301 of the target object 1306; determining an object side 1303 corresponding to the object adsorption plane 1302; the target side 1303 and the target suction plane are overlapped, and a center point 1304 of the target side 1303 corresponds to an intersection 1305 of the ray and the target suction plane.

In a second implementation manner, please refer to fig. 14 and 15, in which fig. 14 is a schematic side view of the target object moving to the target position, and fig. 15 is a schematic view of a scene for confirming placement of the target object. A preset point on the target object (e.g. a center point) is moved to the target position 1501 for the processing device.

It should be noted that, in this implementation, the grid in the spatial editing region provides an alignment standard, and since calculating the offset vector requires determining coordinates of two points, that is, a start point coordinate and an end point coordinate, and determining the end point coordinate as a preset point on the object, the start point coordinate is a central point of a side of the target grid, the target grid includes at least one cube grid, and the central point of the side of the target grid is a central point of a side of the cube. Therefore, in the scene corresponding to fig. 9, it is necessary to calculate the center position of the mesh where the intersection point is located as a point f from the intersection point o.

It should be noted that there is a possibility that the central position calculated according to the above formula 1 is illegal, that is, the target grid for accommodating the object is located outside the editing area, and at this time, the position of the object needs to be moved to the nearest legal position, that is, the target grid for accommodating the target object is completely located inside the editing area, please understand with reference to fig. 16, and fig. 16 is a schematic side view of the target object moving to the target position.

Finally, the intersection of the target object with other placed objects is determined. If there is an intersection (i.e., the object model intersects, and/or the target grid to which the target object belongs intersects with the grid to which the placed object belongs), then the target object is displayed in a red bounding box and the player is not allowed to confirm the placement. If there is no intersection, the object is displayed in a green bounding box, allowing confirmation of placement.

In the embodiment of the invention, the user can edit the object quickly, the calculated amount is small, the object editing method is simple, the common user can simply master the object, and the operation mode can accord with the intuition habit of the user.

Further, the above embodiment is a method for moving and placing an object, and on the basis of the above embodiment, another embodiment is provided in the embodiments of the present invention, and in this embodiment, methods for finely editing a target object, such as translation, rotation, and zooming, are provided.

1. Translation:

this embodiment may be a Gizmo-based fine editing mode. In this fine editing mode, the user is free to adjust the position, rotation, and zoom of the object. Please refer to fig. 17 and 18 for understanding, fig. 17 is a schematic view of a panning direction, and fig. 18 is a schematic view of a scene of an editing mode. The object can be translated in both positive and negative directions in each of the three axes X, Y, Z, so there are a total of 6 directions of movement. The 6 moving directions are + X direction, -X direction, + Y direction, -Y direction, + Z direction, -Z direction, respectively, and 6 arrows pointing to different axial directions are provided as the translation Gizmo1801 for translating the target object in the embodiment of the present invention.

The input device detects an operation of selecting a translation object input by a user, the input device generates operation data according to the operation of selecting the translation object and sends the operation data to the processing device, then the processing device generates a ray according to the operation data, the ray points to an arrow in an upward direction (a + Z direction), the processing device determines that the translation direction of the target object is a + Z direction, and generates a first position coordinate according to the operation data, wherein the first position coordinate is a coordinate of the translation Gizmo (a coordinate of the arrow in the upward direction and is marked as 'P _ Gizmo'); for example, if the user selects the up arrow, the processing device determines that the translation direction of the target object (e.g., a checkerboard) is moving in the positive direction of the Z-axis, while the X and Y coordinates do not change.

The processing device calculates a second position coordinate (denoted "P _ Center") of a preset point on the target object, which may be a Center point on the target object.

When a user moves the position of the input device up and down in a real environment, for example, the user translates the input device up, the input device detects an operation of translating an object input by the user, the input device generates operation data and sends the operation data to the processing device, the processing device generates a ray for translating a target object according to the operation data and calculates a third position coordinate according to the operation data, the third position coordinate is on a coordinate axis (such as an X axis) corresponding to the translation operation, the coordinate axis is regarded as a spatial straight line, the ray is also regarded as a spatial straight line, and the corresponding coordinate axis and the ray have a shortest distance, for example, the distance between the third position coordinate (denoted as "P _ Near") on the X axis and a target point on the ray is the shortest distance between the two spatial straight lines, the third position coordinate is determined.

The processing device calculates a fourth position coordinate (denoted as 'P _ New') of the preset point after the target object is translated according to the first position coordinate, the second position coordinate and the third position coordinate; the specific formula 2 for calculating the fourth position coordinate is as follows:

P_New＝P_Center+P_Near-P_Gizmo；

and the processing device moves the preset point of the target object to the fourth position coordinate in the translation direction and displays the preset point through the display device.

2. Rotating:

the object can rotate around three axes of X, Y and Z, as can be understood with reference to fig. 19, fig. 19 is a schematic view of the rotation direction of the object. One rotation Gizmo (shown as a corner-shaped Gizmo1802 in fig. 18) for rotating the object is arranged outside the four edges of the bounding box corresponding to each axis, wherein the rotation Gizmo1901 corresponding to the X axis, the rotation Gizmo1902 corresponding to the Y axis, the rotation Gizmo1903 corresponding to the Z axis, and the rotation Gizmo are 12 in total.

This way, the player can edit a certain attribute of the object separately.

The processing equipment receives an operation of selecting a rotating object detected by the input equipment; the player can make targeted edits by ray-selecting any of the 12 spins Gizmo and then turning the handle.

The processing device determines a rotation direction of the target object according to the operation of selecting the rotation object and records a current first rotation component (denoted as "R") of the target object and a current first euler angle of the input device according to the operation of selecting the rotation object, wherein the first euler angle comprises a Pitch value and a Yaw value, the Pitch value is an initial value of an angle of rotation of the input device around an X axis, denoted as "R _ Pitch", and the Yaw value is an initial value of an angle of rotation of the input device around a Y axis, denoted as "R _ Yaw";

the processing device detects an operation of the rotating object detected by the input device. For example, when the user selects the rotation Gizmo corresponding to the Y-axis and rotates the input device (e.g., the handle) up and down, the object rotates around the Y-axis, and the rotation angle on the other axes remains unchanged.

The processing device calculates a second Euler angle after the input device is rotated according to the operation of the rotating object, wherein the second Euler angle comprises Pitch and Yaw values after the input device is rotated, the Pitch after the rotation is recorded as 'R _ NewPitch', and the Yaw value after the rotation is recorded as 'R _ Newyaw';

the processing device calculates a second rotation component after the target object is rotated according to the first rotation component, the first euler angle and the second euler angle, and a calculation formula 3 for calculating the second rotation component is as follows:

r _ New ═ R + k × (R _ NewPitch + R _ NewYaw-R _ Pitch-R _ Yaw); where k is the sensitivity factor, the user can customize the setting, and k × (R _ NewPitch + R _ NewYaw-R _ Pitch-R _ Yaw) is the rotation value.

The processing device rotates the target object by the second rotation component on the basis of the first rotation component and displays it by the display device.

3. Zoom

Zooming is similar to the principle of rotation, and zooming can be set to only one zoom Gizmo (left cube Gizmo1803 in FIG. 18).

The processing device receives an operation of selecting a zoom object detected by the input device, for example, in an application scenario, a user selects zoom Gizmo, which can also be understood as that the user inputs a zoom instruction.

The processing device records a current first space size (denoted as "M") of the target object, which is a volume of the target object before the target object is not zoomed, according to an operation of selecting the zoom object, and records a current third euler angle of the input device, which includes a Pitch value, which is an initial value of an angle of rotation of the input device about the X-axis, denoted as "R _ Pitch", and a Yaw value, which is an initial value of an angle of rotation of the input device about the Y-axis, denoted as "R _ Yaw".

The processing device receives an operation of zooming the object detected by the input device, for example, a user rotates the input device, and the input device detects an operation of zooming the target object.

The processing device calculates a fourth Euler angle after the input device is rotated according to the operation of the zoom object, wherein the fourth Euler angle comprises Pitch and Yaw values after the input device is rotated, the Pitch after the rotation is recorded as 'R _ NewPitch', and the Yaw value after the rotation is recorded as 'R _ Newyaw';

the processing device calculates a second space size of the target object after scaling according to the first space size, the third euler angle and the fourth euler angle, and a calculation formula 4 for calculating the second space size is as follows:

m _ New ═ M × k × (R _ NewPitch + R _ NewYaw-R _ Pitch-R _ Yaw); k is a sensitivity coefficient, and a user can customize the setting; k × (R _ NewPitch + R _ NewYaw-R _ Pitch-R _ Yaw) is the zoom value calculated from the user turning the input device.

The processing device zooms the target object to a second space size based on the first space size and displays the target object through the display device.

According to the embodiment of the invention, the convenience degree of editing operation on the object under VR can be greatly improved, the editing method provided by the embodiment of the invention can enable a common player to quickly and conveniently put the object, and can also finely adjust the pose and the zoom attribute of the object, so that the player can freely edit the object in VR.
