It is known to those skilled in the art that with the evolution of data processing and the emergence of new business scenarios, the technical solution provided by the present application is also applicable to similar technical problems.

[0038] The solutions provided by the embodiments of the present application are specifically described by the following embodiments. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0039] This embodiment will be described from the perspective of a model processing device. The model processing device may be integrated into an electronic device. The electronic device may be a terminal and / or a server, and this application does not limit this.

[0040] See also Figure 2 , Figure 2 : is a flow chart of the model processing method provided in the embodiment of the present application. The model processing method includes:

[0041] In step 101, a control model is obtained.

[0042] Wherein, a plurality of control points are set on the control model.

[0043] The control model may be a model for constructing a deformation effect, and the deformation effect may include a splitting effect. The control point may be a point set in the control model.

[0044] Optionally, the control point may be a point at which movement occurs in the control model.

[0045] There are many ways to obtain the control model. For example, an initial control model can be constructed, which includes multiple line segments sharing a starting endpoint. On each line segment in the initial control model, multiple control points are randomly generated to obtain a control model, wherein the control points are configured to perform circular motion along the line segments toward the starting endpoint.

[0046] The initial control model may be a model for constructing a region where a deformation effect occurs. The initial control model may include multiple line segments, each line segment may have the same length, and the number of line segments included in the initial control model may be set according to actual needs, for example, 3, 7 or 9 line segments may be included. The starting endpoint may be an endpoint serving as the starting point of the line segment.

[0047] For example, see Figure 3a , Figure 3aThis is a schematic diagram of an initial control model of a model processing method provided in an embodiment of the present application. The initial control model may include seven line segments, all of which share a common starting endpoint as the center of the initial control model. Specifically, a line segment of any length may be created, and the created line segment may be copied 6 times. Each time the line segment is copied, the line segment may be copied by moving 360° / 7=51.4286° around the starting endpoint, so that the copied line segments may be distributed around the starting endpoint to form a circle, thereby obtaining an initial control model including multiple line segments sharing a common starting endpoint.

[0048] Among them, the number of randomly generated control points on each line segment can be the same or different, and the number of generated control points can also be set according to actual needs, which is not limited in the embodiment of the present application.

[0049] For example, see Figure 3b , Figure 3b It is a control model schematic diagram of a model processing method provided in an embodiment of the present application. Multiple control points can be randomly generated on each line segment of the initial control model. The number of randomly generated control points on each line segment can be the same or different. Each control point can be configured with a corresponding point number, and each point number is used to identify a control point.

[0050] Optionally, the control points in the control model can be configured to perform circular motion along the line segment toward the starting endpoint, so as to achieve an infinite loop of inward collapse deformation motion special effects in subsequent operations. For example, each control point can be configured to move from the initial position along the line segment toward the starting endpoint, and when the control point reaches the starting endpoint, it returns to the terminal endpoint of the line segment, and then continues to move from the position of the terminal endpoint along the line segment toward the starting endpoint until the control point reaches the starting endpoint, and then the control point returns to the terminal endpoint of the line segment, and continues to move from the terminal endpoint along the line segment toward the starting endpoint, thereby achieving circular motion of the control point on the line segment.

[0051] In one embodiment, there may be multiple ways to configure a control point to perform circular motion along the line segment in which it is located toward the starting endpoint. For example, a third distance from the control point to the starting endpoint of the line segment in which it is located may be obtained; a motion control parameter of the control point at the current moment may be determined based on the third distance, and the motion control parameter may cyclically change over time within a range of 0 to a target value; based on the motion control parameter, a target distance from the control point at the current moment to the starting endpoint of the line segment in which it is located may be determined; and the control point may be controlled to perform circular motion based on the target distance.

[0052] Among them, the third distance can be the distance between the control point and the starting endpoint at the current moment, the motion control parameter can be a parameter that changes cyclically over time within the range of 0 to a target value, and can be used to control the control point to perform cyclic motion on the line segment, and the target value can be a value indicating the maximum range of cyclic motion of the control point on the line segment, for example, it can be the distance value between the starting endpoint and the ending endpoint of the line segment, that is, the length of the line segment, so that 0 can indicate the location of the starting endpoint, and the target value can indicate the location of the ending endpoint. Optionally, the line segment length can also be normalized, that is, the target value can be 1, so that 0 can indicate the location of the starting endpoint, and 1 can indicate the location of the ending endpoint. The target distance can be the distance between the position that the control point should reach at the next moment of the current moment and the starting endpoint.

[0053] Among them, there can be many ways to determine the motion control parameters of the control point at the current moment based on the third distance. For example, the length of the line segment and the motion control function can be obtained, and the third distance can be divided by the length of the line segment to obtain the position ratio value corresponding to the control point. Then, the motion control parameter of the control point at the current moment can be determined based on the position ratio value and the time function through the motion control function.

[0054] The motion control function may be a function for generating a value that changes cyclically over time within a range from 0 to a target value based on a current position of the control point.

[0055] For example, the length of the line segment can be mapped to a range between 0 and 1, where 0 is the position of the starting endpoint and 1 is the position of the terminating endpoint of the line segment. That is, taking the target value of 1 as an example, all control points can be traversed. For each control point, the position of the current control point P can be obtained, so that the distance between the control point P and the starting endpoint of the line segment, that is, the third distance, can be queried. The third distance is divided by the length of the line segment to obtain the position ratio value t. The position ratio value t can indicate the ratio of the current position of the control point to the length of the line segment. For example, assuming that the length of the line segment is 2 meters and the control point is 1 meter away from the starting endpoint, the third distance is 1 meter and the position ratio value t is 0.5. Then, the motion control parameter T corresponding to the control point at the current moment can be determined based on the position ratio value t through the motion control function. The motion control function can be expressed as:

[0056] T = frac(t-(time*0.25))

[0057] Among them, frac() represents a function for taking the decimal part of a real number, time can represent a time function and can be used to obtain the current time, t can represent the position ratio value corresponding to the third distance, and T can represent the motion control parameter. In this way, based on the third distance, a value that changes in a cycle from 0 to 1 can be obtained, namely the motion control parameter. Therefore, the target distance from the control point to the starting end point of the line segment at the current moment can be calculated according to the motion control parameter and the length of the line segment. For example, assuming that the motion control parameter is 0.4 and the length of the line segment is 2 meters, the target distance can be 2×0.4=0.8, that is, at the next moment, the distance from the position of the control point to the starting end point is 0.8 meters. Therefore, the value of the target distance can be assigned to the current control point to control the movement of the control point.

[0058] In a specific embodiment, for each control point, the position P of the current control point can be obtained, the position of the starting endpoint is P0, and the ending endpoint of the line segment is P1. Let P1-P0, and the vector P0P1 with both magnitude and direction from P0 to P1 can be obtained. Let P-P0, and the vector P0P from P0 to the current control point P can be obtained. The projection length of the vector P0P on the vector P0P1 is calculated, and then the projection length is divided by the modulus length of the vector P0P1, that is, the line segment length, so that the projection length can be normalized to obtain the position ratio value t , when t=1, it means that the control point is at the end endpoint P1 of the line segment, and when t=0, it means that the control point is at the start endpoint P0 of the line segment. Then, through the motion control function T=frac(t-(time*0.25)), the motion control parameters corresponding to the control point that cycle continuously between 0 and 1 are obtained. Therefore, according to the line segment length and the motion control parameters, the target distance between the position that the control point needs to reach at the current moment and the start endpoint of the line segment can be calculated, so that the control point can be moved to a position at the target distance from the start endpoint.

[0059] In step 102, a bounding box model of the bounding control model is created, and a target plane facing the virtual camera in the bounding box model is determined.

[0060] The bounding box model may be a model that encloses the control model. The bounding box model may be configured with a material based on the effect to be achieved, so that the bounding box model is visible and has a specific material. For example, when the deformation motion special effect of ground collapse needs to be achieved, the material of the bounding box model may be set to the material of the ground model. When the collapse effect of any plane needs to be achieved, the material of the bounding box model may be set according to actual needs. The virtual camera may be a virtual camera in the virtual scene where the control model is located, and the target plane may be a plane in the bounding box model that faces the virtual camera.

[0061] Optionally, after determining the target plane, the target plane may be extracted, and other planes in the bounding box model may be deleted, leaving only the plane model of the target plane.

[0062] For example, see Figure 3c , Figure 3c It is a target plane schematic diagram of a model processing method provided in an embodiment of the present application, which can extract the target plane facing the virtual camera.

[0063] There are many ways to determine the target plane facing the virtual camera in the bounding box model. For example, the normal vector of each plane in the bounding box model and the camera direction vector of the virtual camera can be obtained, and based on the normal vector and the camera direction vector, the angle information between the normal direction of the plane and the camera direction of the virtual camera is calculated, and the target plane facing the virtual camera is determined in the plane based on the angle information.

[0064] Among them, the normal vector can be the vector of the normal of each plane in the bounding box model, the camera direction vector can be the vector of the camera direction of the virtual camera, and the angle information can be information indicating the angle between the normal of the plane and the camera direction, so that according to the angle information, the target plane facing the virtual camera can be determined among the multiple planes of the bounding box.

[0065] Among them, based on the normal vector and the camera direction vector, there are many ways to calculate the angle information between the normal direction of the plane and the camera direction of the virtual camera. For example, the dot product of the normal vector and the camera direction vector can be calculated to obtain the cosine value of the angle between the normal direction of the plane and the camera direction of the virtual camera, that is, to obtain the angle information between the normal direction of the plane and the camera direction of the virtual camera.

[0066] In step 103, the target plane is segmented based on the current positions of the multiple control points to obtain the segmentation plane corresponding to each control point in the target plane.

[0067] The segmentation plane may be a plurality of planes obtained by segmenting the target plane. Thus, the plurality of segmentation planes segmented in the target plane may be used to simulate a region with a splitting effect, so that target deformation motion effects may be achieved based on the plurality of segmentation planes, such as ground cracking and collapse, space collapse, object explosion, and the like.

[0068] Among them, there are many ways to segment the target plane based on the current positions of multiple control points to obtain the segmentation plane corresponding to each control point in the target plane. For example, based on the current positions of multiple control points, the segmentation indication information corresponding to the target plane can be calculated; based on the segmentation indication information, the target plane is segmented to obtain the segmentation plane corresponding to each control point in the target plane.

[0069] The segmentation indication information may be information indicating how to segment the target plane based on each control point, and may indicate an area corresponding to each control point in the target plane.

[0070] There are multiple ways to calculate the segmentation indication information corresponding to the target plane based on the current positions of multiple control points. For example, the first distance between each position point and each control point in the target plane can be calculated based on the current positions of multiple control points; the target position point corresponding to each control point is determined according to the first distance; and the segmentation indication information corresponding to the target plane is generated based on the target position point corresponding to each control point, and the segmentation indication information indicates the area corresponding to each control point in the target plane.

[0071] The first distance may be the distance between each position point and each control point in the target plane, and the position point may be a point in the target plane. The first distance between each position point and each control point in the target plane may be calculated by acquiring the world coordinates of each control point and the world coordinates of each position point in the target plane. The target position point corresponding to each control point may be a position point on a segmentation plane that is assigned to the control point when segmenting the target plane.

[0072] Optionally, the distance between the target position point corresponding to each control point and its corresponding control point is smaller than the distance between the target position point and other control points.

[0073] In one embodiment, the segmentation indication information may be Voronoi noise, which may also be called cell noise, etc. For example, each control point may be used as a seed point to divide the position points in the space corresponding to the target plane to obtain Voronoi noise. The Voronoi noise may indicate the target position points in the segmentation plane corresponding to each control point among the position points of the target plane. Optionally, the Voronoi noise may be a noise map, in which unit areas corresponding to each control point are distributed, and the target position points corresponding to each control point are located in the unit area corresponding to the corresponding control point. Thus, based on Voronoi noise, the target plane may be divided into a plurality of unit areas, each unit area being a segmentation plane, each segmentation plane corresponding to a control point, and the distance between any position point in each segmentation plane and its corresponding control point is less than the distance between any other control points, so that a target plane simulating the splitting effect may be obtained.

[0074] For example, see Figure 3d , Figure 3d is a schematic diagram of a segmentation plane of a model processing method provided in an embodiment of the present application. Based on the segmentation indication information, the target plane can be segmented into multiple segmentation planes to obtain a target plane that simulates the splitting effect. Figure 3dIn the example, the point number of the corresponding control point can be displayed in each split plane.

[0075] Optionally, since the control points perform cyclic motion in the control model, the current positions of multiple control points in the control model can be obtained in real time, so that the target plane can be dynamically segmented based on the current positions of multiple control points in real time to obtain the segmentation plane corresponding to each control point in the target plane. Therefore, the segmentation plane corresponding to the target plane is dynamically changing, which can be used to achieve dynamic splitting and cyclic collapse target deformation motion effects. For example, please refer to Figure 3e , Figure 3e is another segmentation plane schematic diagram of a model processing method provided by an embodiment of the present application. Since the control points are in continuous cyclic motion, the positions of the control points acquired at different times are dynamically changing. Figure 3d The splitting plane shown is Figure 3e There are differences in the segmentation planes shown. Therefore, the target plane is segmented based on the positions of the dynamically changing control points, and the dynamically changing segmentation planes in the target plane can be segmented.

[0076] In step 104, the movement parameters required for each segmentation plane to achieve the target deformation motion effect are determined.

[0077] Wherein, the movement parameters of at least two segmentation planes are different. The target deformation motion special effect may be a special effect for simulating the deformation motion of an object, for example, it may include special effects such as ground cracking and collapsing, space collapse, and object explosion. The movement parameter may be a parameter for controlling the segmentation plane determined based on the target deformation motion special effect to be achieved.

[0078] Among them, there may be multiple ways to determine the movement parameters required for each segmentation plane to achieve the target deformation motion effect. For example, the movement parameters may include a movement direction and a movement distance, and a second distance between each segmentation plane and the center position of the target plane may be calculated; based on the second distance, the movement distance required for each segmentation plane to achieve the target deformation motion effect is determined, and the movement direction of each segmentation plane that matches the target deformation motion effect is obtained.

[0079] The moving direction may be the direction in which the splitting plane is moved, and the moving distance may be the distance in which the splitting plane is moved. The second distance may be the distance between each splitting plane and the center position of the target plane. The second distance between each splitting plane and the center position of the target plane may be calculated by obtaining the world coordinates of the center position of the target plane and the world coordinates of the center position of the splitting plane. The second distance between each splitting plane and the center position of the target plane may also be calculated by obtaining the world coordinates of the starting endpoint in the control model and the world coordinates of the control point corresponding to the splitting plane.

[0080] Among them, there can be many ways to determine the moving distance required for each segmentation plane to achieve the target deformation motion effect based on the second distance, and to obtain the moving direction of each segmentation plane that matches the target deformation motion effect. For example, the second distance can be used as the moving distance required for each segmentation plane to achieve the target deformation motion effect, and to obtain the moving direction of each segmentation plane that matches the target deformation motion effect. For example, if the target deformation motion effect is an inward circular collapse effect, the moving direction can be upward, and the closer the segmentation plane is to the center of the target plane, the smaller the moving distance, and the farther the segmentation plane is from the center of the target plane, the larger the moving distance. Therefore, the target deformation motion effect of the object collapsing inward can be achieved by controlling the dynamically changing segmentation plane to move a corresponding moving distance in the upward direction. For another example, if the target deformation motion effect is an outward explosion effect, the moving direction may be obliquely upward, and the moving directions corresponding to each segmentation plane may be offset; the closer the segmentation plane is to the center of the target plane, the closer its moving direction is to directly upward; the farther the segmentation plane is from the center of the target plane, the more its moving direction deviates from directly upward; the closer the segmentation plane is to the center of the target plane, the greater its moving distance; the farther the segmentation plane is from the center of the target plane, the smaller its moving distance, etc., thereby achieving the target deformation motion effect of the object exploding outward by controlling the dynamically changing segmentation plane to move the corresponding moving distance in the upward direction.

[0081] In step 105, the movement of the segmentation plane is controlled according to the movement parameters to obtain a target model with target deformation motion effects.

[0082] Among them, the target model can be a model with target deformation motion effects. In the target model, there are multiple segmentation planes that move according to corresponding movement parameters, thereby simulating the target deformation motion effects of splitting multiple blocks in the object and moving.

[0083] There are many ways to control the movement of the segmentation plane according to the movement parameters to obtain a target model with target deformation motion effects. For example, each segmentation plane can be controlled to move a certain distance along the movement direction according to the movement parameters to obtain a target model with target deformation motion effects.

[0084] Among them, there are many ways to control each segmentation plane to move a moving distance along a moving direction according to the moving parameters, and obtain a target model with a target deformation motion effect. For example, according to the moving parameters, the moving distance can be used as the extrusion height, and an extrusion operation can be performed on each segmentation plane in the moving direction to obtain a target model with a target deformation motion effect.

[0085] The extrusion operation may be an operation of extending the plane along the normal direction to create a three-dimensional model with thickness. The extrusion height may be the height of the extrusion of the segmentation plane. For example, taking the target deformation motion special effect as the special effect of inward circular collapse as an example, the extrusion operation may be performed on each segmentation plane in the upward direction according to the moving parameter and the moving distance as the extrusion height, so as to obtain a target model with the target deformation motion special effect based on the segmentation planes with different extrusion heights and three-dimensional effects.

[0086] Optionally, there are multiple ways to obtain a target model with target deformation motion effects by controlling each segmentation plane to move a distance along a moving direction according to a moving parameter. For example, for each segmentation plane, the segmentation plane can be copied to obtain a copy plane; according to the moving parameter, based on the initial position of the segmentation plane, the copy plane can be moved the distance along the moving direction; the corresponding vertices on the copy plane and the segmentation plane are connected to form a facade connecting the copy plane and the segmentation plane, thereby obtaining a target model with target deformation motion effects.

[0087] The copy plane may be a plane obtained by copying the split plane, the initial position may be the position of the split plane, and the elevation may be a plane connecting the copy plane and the split plane, so that a three-dimensional model corresponding to the split plane can be obtained to more realistically simulate the target deformation and motion effects. Since the vertices on the copy plane have the same serial number as the corresponding vertices on the corresponding split plane, before rendering, it can be declared that the copy plane and the corresponding vertices on the split plane are in the same plane, so that a elevation connecting the copy plane and the split plane can be rendered.

[0088] In one embodiment, the target deformation motion special effect is an inward loop collapse special effect as an example, please refer to Figure 4a , Figure 4a It is a schematic diagram of a target model of a model processing method provided in an embodiment of the present application. After the target plane is segmented to obtain multiple segmentation planes, the moving distance can be used as the extrusion height, or the moving distance can be normalized and the normalized moving distance can be used as the extrusion height, thereby performing an extrusion operation on each segmentation plane in an upward direction. Since the moving distances corresponding to segmentation planes with different distances from the center position of the target plane are also different, based on the extrusion heights and three-dimensional effects corresponding to each segmentation plane, the special effects of inward circular collapse can be simulated more realistically and accurately, thereby obtaining a target model with target deformation motion special effects and better effects.

[0089] In addition, since the control points in the control model perform cyclic motion, the segmentation plane obtained by segmenting the target plane based on the moving control points also changes in real time, so the process of moving the segmentation plane according to the movement parameters also changes dynamically. For example, please refer to Figure 4b , Figure 4b is another target model schematic diagram of a model processing method provided in an embodiment of the present application. It can be seen that: Figure 4a and Figure 4b The target model shown has different target deformation motion effects. Based on this, dynamically changing target deformation motion effects can be generated based on the control points that control the cyclic motion in the model, which simplifies the difficulty of generating the target deformation motion effects and effectively improves the model processing efficiency.

[0090] In game development projects, it is usually necessary to create some special special effects to enhance the game effect. For example, by processing the three-dimensional model to generate deformation motion special effects such as ground cracks and collapse. However, the existing model processing method generates model deformation motion special effects such as space collapse, which is relatively complicated and difficult to generate, resulting in low model processing efficiency. To this end, the embodiment of the present application proposes a model processing method that can programmatically and quickly generate special effects such as infinite loop inward collapse, so that such special effects requirements can be quickly realized, greatly reducing the development difficulty and manufacturing cycle of such special effects.

[0091] As can be seen from the above, the embodiment of the present application obtains a control model, and a plurality of control points are set on the control model; creates a bounding box model surrounding the control model, and determines the target plane facing the virtual camera in the bounding box model; based on the current positions of the plurality of control points, the target plane is segmented to obtain the segmentation plane corresponding to each control point in the target plane; determines the movement parameters required for each segmentation plane to achieve the target deformation motion effect, wherein the movement parameters of at least two segmentation planes are different; controls the movement of the segmentation plane according to the movement parameters to obtain a target model with the target deformation motion effect. In this way, by constructing a control model and a bounding box model surrounding the control model, the target plane facing the camera in the bounding box model is segmented based on the current positions of the plurality of control points in the control model, so as to construct a plane simulating the fission effect based on each segmentation plane, so as to obtain a target model with the target deformation motion effect by controlling the movement of each segmentation plane according to the movement parameters, so as to achieve the generation of target deformation motion effects such as space collapse, simplify the difficulty of generating target deformation motion effects, and thus effectively improve the model processing efficiency.
