[0057] Next, Figure 1 Taking the electronic device 1000 as an example of an implementation subject, various embodiments of the virtual object data processing method are described.

[0058] <First Embodiment>

[0059] Figure 2 A data processing method for a virtual object according to some embodiments is shown, and the data processing method for a virtual object may include the following steps S210 to S230:

[0060] Step S210 , in response to a display instruction of the target object, determining first feature information indicating a position of a first vertex of the target object.

[0061] In this embodiment, the display instruction of the target object can be triggered by the user's operation, for example, the user triggers the display instruction by performing a drag gesture operation on the touch screen of the electronic device, or it can be triggered when the game process reaches a set game node, for example, the game system triggers the display instruction after the user completes a game task.

[0062] In this embodiment, the target object may be a virtual object set in a virtual scene, such as a stone, a tree, or a screen, and is set in a virtual scene. The vertex on the outline of the virtual object is the first vertex, and the first feature information may indicate the position of the first vertex in the virtual scene.

[0063] Step S220: obtaining the anchor point position of the target object according to the first feature information.

[0064] In this embodiment, the target object can be composed of multiple facets, and the position of each facet can be represented by the position of the center point of each vertex of the facet. The center point of all facets on an object is the anchor point of the object, and the position of the target object anchor point in the virtual scene is the anchor point position.

[0065] Step S230, obtaining the rotation angle of the facet surrounded by the first vertex of the target object according to the observation information of the target object and the anchor point position; wherein the rotation angle is used to set the moving path of the first vertex of the target object.

[0066] In this embodiment, the observation information of the target object may include the setting position of the target camera in the virtual scene. By calculating the difference between the anchor point position and the setting position of the target camera, the rotation angle of the face surrounded by the first vertex of the target object can be obtained. By using the rotation angle, the target object rotates around its anchor point on the y-axis, and the face of the target object can also be dynamically adjusted as the camera moves or the scene requires.

[0067] In this embodiment, the relative position of the center point of the patch surrounded by the first vertices and the first vertex is set, and the relative position of the center point of the patch surrounded by the first vertices and the anchor point of the target object is also set. Then, in the virtual scene, after the target object rotates around its anchor point by a rotation angle, the position of the center point of the patch surrounded by the first vertices and the anchor point of the target object does not change. The patch surrounded by the first vertices takes the center point of the patch surrounded by the first vertices as the rotation center, and rotates the rotation angle to obtain the moving path of each first vertex, that is, the final position in the moving path of the first vertex is obtained. The final position in the moving path can represent the posture change of the patch surrounded by the first vertices, so as to achieve that the patch of the target object can always face the camera.

[0068] In some embodiments, there are a large number of virtual models in the virtual scene, and some of the virtual models need to adjust their patch poses. In order to screen out the target model that needs to adjust the patch pose from the large number of virtual models, the target object is at least a part of the target model, and a first number of the target objects in the target model is greater than a set threshold, wherein the set threshold is related to the total number of objects configured in the target model.

[0069] In this embodiment, a model in a virtual scene can be configured with multiple sub-objects. When the first number of sub-objects of a specific type in the model is greater than a set threshold, the model is the target model, and the sub-objects of the set type are the target objects. The sub-objects of the specific type are, for example, virtual trees, virtual stones, or virtual pillars. For example, if the model is a virtual mountain, the threshold is set to 10%, the number of virtual trees configured in the virtual mountain accounts for 12% of the total number of sub-objects configured in the virtual mountain, and the number of virtual trees is greater than the total number of objects configured in the virtual mountain, the virtual mountain is the target model, and the virtual trees are the target objects.

[0070] The data processing method for virtual objects according to the first embodiment of the present invention solves the problem in the prior art that when some virtual objects are arranged in a virtual scene, the virtual objects will be rotated or moved, and the facets cannot always face the camera, which makes the presented game screen rough. Based on this method, when the target object needs to be displayed, the first feature information representing the position of the first vertex of the target object is determined, and the anchor point position of the anchor point of the target object is determined through the first feature information, and then the rotation angle of the facet of the target object is set according to the anchor point position and the observation information, so that after the target object is rotated or moved, the facet of the target object can always face the camera through the adjustment of the rotation angle, so as to improve the quality of the presented game screen.

[0071] <Second Embodiment>

[0072] In this embodiment, in order to save the cost of the electronic device, the first feature information indicating the position of the first vertex of the target object may be stored in the second set color channel of the first vertex.

[0073] In these embodiments, relative to the first embodiment, before step S210, the method further includes the following steps S310 to S360:

[0074] Step S310 , in response to a configuration operation of the target object, configuring a first identifier for a first set color channel of a first vertex of the target object.

[0075] In this embodiment, the first set color channel belongs to one of the vertex color channels, and the vertex color channel may include an R channel, a G channel, and a B channel. The first set color channel among the R channel, the G channel, and the B channel of the target object may be configured with a first identifier. For example, the first set color channel is the R channel, and during the configuration of the virtual object, the first identifier is set to "0", and through the vertex shader, the R channel of the virtual object vertex is assigned a value of "0" to set the virtual object as the target object.

[0076] Step S320: input the third feature information of the first vertex into a preset union-find set.

[0077] In this embodiment, the third feature information may be the first vertex of the target object and the edge connecting the first vertex. The third feature information is input into a preset union-find set, and the first vertices on the target object can establish an association relationship, that is, establish connected components of each target object to identify all first vertices in the target object.

[0078] Step S330, determining the anchor point position of the target object's anchor point according to the union-find set.

[0079] In this embodiment, the relevant vertex set of the target object, that is, the vertex set of the first vertices, can be identified by the union-find set. Then, by calculating the average value of the vertex positions of these first vertices, the center position of the geometric center of the target object is obtained, and the geometric center is the anchor point of the target object, and the center position is the anchor point position of the anchor point of the target object.

[0080] Step S340: determining a vector difference between the first vertex of the target object and the anchor point according to the position of the anchor point.

[0081] In this embodiment, when the positions of each first vertex and anchor point are determined, the distance from the first vertex to the anchor point can be calculated, and the maximum value range of these distances and the vector difference between the first vertex and the anchor point can be determined.

[0082] Step S350: normalize the vector difference to obtain first feature information indicating the position of the first vertex.

[0083] In this embodiment, the normalization process may be: dividing the vector difference from each vertex to the anchor point by the maximum value range to obtain a normalized value of the first vertex, and using the normalized value of the first vertex as the first feature information representing the position of the first vertex.

[0084] Step S360: input the first feature information into the second set color channel of the first vertex.

[0085] In this embodiment, the normalized value of the first vertex is stored in the second set color channel of the first vertex as the first feature information of the first vertex. The second set color channel here can be the first set color channel, or it can be another color channel different from the first set color channel. In other words, by storing the first feature information in the second set color channel of the first vertex, the utilization efficiency of the storage space of the electronic device can be effectively improved.

[0086] <Third Embodiment>

[0087] In this embodiment, in order to quickly determine the anchor point position of the target object, the first vertex of the target object can be identified and managed by setting and finding, which effectively improves the efficiency of determining the anchor point position.

[0088] In these embodiments, relative to the above second embodiment, step S330 may include the following step S410:

[0089] According to the connected components of the target object reflected in the union query set, the geometric center of the first vertex of the target object and the center position of the geometric center are determined and used as the anchor point position of the target object.

[0090] In some examples, the target object is set in a three-dimensional virtual scene, and the x coordinate, y coordinate, and z coordinate of the first vertex of the target object can be determined by union-finding, and the average value of the x coordinate of the first vertex, the average value of the y coordinate of the first vertex, and the average value of the z coordinate of the first vertex are calculated. The average value of the x coordinate is used as the x coordinate of the anchor point of the target object, the average value of the y coordinate is used as the y coordinate of the anchor point of the target object, and the average value of the z coordinate is used as the z coordinate of the anchor point of the target object.

[0091] <Fourth Embodiment>

[0092] In this embodiment, in order to ensure that the facet of the target object always faces the camera to provide a better visual effect, the observation information may include the setting position of the target camera, and the rotation angle of the facet of the target object and the moving path of the first vertex are determined by the position difference between the setting position and the anchor point position.

[0093] In these embodiments, compared with the first embodiment, step S230 may include the following steps S510 and S520:

[0094] Step S510, obtaining the rotation angle of the facet surrounded by the first vertex of the target object according to the position difference between the set position and the anchor point position.

[0095] In this embodiment, the observation information of the target object may include the setting position of the target camera in the virtual scene. By calculating the difference between the anchor point position and the setting position of the target camera, the rotation angle a of the face surrounded by the first vertex of the target object can be obtained. By using the rotation angle a, while the target object rotates around its anchor point on the y-axis, the face of the target object can also be dynamically adjusted as the camera moves or the scene requires. For example, when the target object is a virtual tree, when the virtual tree rotates around its anchor point on the y-axis, the branches and leaves on the virtual tree, as the face of the virtual tree, can also be dynamically adjusted as the camera moves or the scene requires.

[0096] Step S520: determining a moving path of the first vertex of the target object according to the rotation angle and the vertex position of the first vertex of the target object.

[0097] In this embodiment, if Figure 1 As shown, the relative position of the center point of the patch P1 surrounded by the first vertices and the first vertex is set, and the relative position of the center point of the patch P1 surrounded by the first vertices and the anchor point of the target object is also set. Then, in this virtual scene, after the target object rotates an angle around its anchor point on the Y axis, the positions of the center point of the patch P1 surrounded by the first vertices and the anchor point of the target object do not change. The patch P1 surrounded by the first vertices is rotated by an angle a with the center point of the patch P1 surrounded by the first vertices as the rotation center, and the moving path of each first vertex can be obtained, that is, the final position in the moving path of the first vertex is obtained. The final position in the moving path can represent the posture change of the patch P1 surrounded by the first vertices, so as to realize that the patch of the target object can always face the camera.

[0098] <Fifth Embodiment>

[0099] In this embodiment, in order to achieve a swaying visual effect of the face on the target object to enhance the rendering power of the picture, the swing amplitude of the first vertex of the target object at different time nodes can be set, and the swing offset of the first vertex can be determined in combination with the rotation angle, so as to achieve a swaying visual effect of the face on the target object while always keeping the face on the target object facing the target camera.

[0100] In these embodiments, compared with the first embodiment, after step S230, the method further includes the following steps S610 to S630:

[0101] Step S610 , in response to a swing setting operation of the target object, obtaining a first vertex position of a second vertex of the target object; wherein the second vertex belongs to the first vertex.

[0102] In this embodiment, the second vertex may be any one of the first vertices, and the first vertex position of the second vertex is a fixed vertex position where the second vertex is located when the target object is set in a three-dimensional virtual scene.

[0103] Step S620: determining the swing amplitude of the second vertex at the first time node according to the position and rotation angle of the first vertex.

[0104] In this embodiment, the swing amplitude can reflect the fluctuation or swing of the second vertex within a given time. Through the rotation angle, the swing direction of the face where the second vertex is located can be perpendicular to the line of sight of the target camera, thereby obtaining a swing effect with better visual experience.

[0105] Step S630: determining the swing offset of the second vertex at the first time node according to the swing amplitude and the rotation angle.

[0106] In this embodiment, the offset position of the second vertex at the first time node can be obtained by swinging the offset and combining it with the known first vertex position of the second vertex, that is, the offset position of the second vertex at the first time node = swinging the offset × the first vertex position of the second vertex.

[0107] <Sixth Embodiment>

[0108] In this embodiment, in order to ensure that the swing direction of the target object's patch is always perpendicular to the line of sight of the target camera, a swing amplitude algorithm is preset. The swing amplitude algorithm can be used to obtain the swing amplitude of the second vertex at the first time node, and then the position of the patch surrounded by the second vertex at the first time node can be obtained, thereby ensuring that the swing direction of the patch at the first time node is perpendicular to the line of sight of the target camera.

[0109] In these embodiments, compared with the fifth embodiment, step S620 may include the following steps S710 and S720:

[0110] Step S710, determining a first position in a first set direction and a second position in a second set direction of a first vertex position; wherein the first set direction and the second set direction are on a set horizontal plane.

[0111] In some examples, such as Figure 3 As shown, the first set direction is, for example, the x direction, the second set direction is, for example, the z direction, the set horizontal plane is, for example, the xz plane, the first position of the first vertex in the first set direction is the x coordinate of the first vertex, and the second position of the first vertex in the second set direction is the z coordinate of the first vertex.

[0112] Step S720: input the first position, the second position, the first time node and the rotation angle into a preset swing amplitude algorithm to obtain the swing amplitude of the second vertex at the first time node.

[0113] In this embodiment, the specific expression of the swing amplitude algorithm is as follows:

[0114] A=sin[xcos(a) + zsin(a) + time] (1)

[0115] In formula (1), A is the swing amplitude, time is the first time node, x is the x coordinate of the first vertex, z is the z coordinate of the first vertex, and a is the rotation angle. The first time node here is generally a moment in the game, such as the 1st second, the 2nd second, or the 10th second. By setting the swing amplitude algorithm, the swing direction can be consistent with the normal of the sight direction of the target camera. As time increases, the swing amplitude algorithm is a sin function, and the value of the sin function can change in the range of [-1, 1], so that the swing direction is perpendicular to the sight direction of the camera.

[0116] <Seventh Embodiment>

[0117] In this embodiment, in order to obtain the swing offset of the second vertex at the first time node to determine the actual position of the second vertex during the swing process, the actual position of the second vertex during the swing process can be determined by setting an offset algorithm.

[0118] In these embodiments, compared with the fifth embodiment, step S630 may include the following step S810:

[0119] Step S810: input the swing amplitude and the rotation angle into a preset offset algorithm to obtain the swing offset of the second vertex at the first time node.

[0120] In this embodiment, the specific expression of the offset algorithm is as follows:

[0121] D1: (sin(a)×A, -cos(a)×A)(2)

[0122] In formula (2), D1 is the second vertex at the first time node, a is the rotation angle, A is the swing amplitude, sin(a)×A is the x-coordinate of the second vertex in the offset position at the first time node, and -cos(a)×A is the z-coordinate of the second vertex in the offset position at the first time node.
