[0039] This embodiment will be described from the perspective of a model processing device, which can be integrated into an electronic device, which can be a terminal and / or a server, and this application does not impose any limitations on it.

[0040] Please see Figure 2 , Figure 2 This is a flowchart illustrating the model processing method provided in an embodiment of this application. The model processing method includes:

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

[0042] The control model has multiple control points.

[0043] The control model can be a model used to construct the deformation effect, which may include a splitting effect. The control point can be a point set in the control model.

[0044] Optionally, the control point can be a point in the control model where motion occurs.

[0045] There are several ways to obtain the control model. For example, an initial control model can be constructed, which includes multiple line segments that share a common starting endpoint. On each line segment in the initial control model, multiple control points are randomly generated to obtain the control model. The control points are configured to move cyclically along their respective line segments toward the starting endpoint.

[0046] The initial control model can be a model used to construct the region where deformation occurs. This initial control model can include multiple line segments, each of which can be of equal length. The number of line segments included in the initial control module can be set according to actual needs; for example, it can include 3, 7, or 9 line segments. The starting endpoint can be the endpoint that serves as the starting point of a line segment.

[0047] For example, please refer to Figure 3a , Figure 3aThis is a schematic diagram of the initial control model of a model processing method provided in this application embodiment. The initial control model may include seven line segments, all of which share the same starting endpoint as the center of the initial control model. Specifically, a line segment of arbitrary length can be created, and the created line segment can be copied 6 times. Each time it is copied, it can be cyclically moved 360° / 7 = 51.4286° around the starting endpoint, so that the copied line segments are 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] The number of control points randomly generated on each line segment can be the same or different, and the number of control points generated can also be set according to actual needs. This application embodiment does not limit this.

[0049] For example, please refer to Figure 3b , Figure 3b This is a schematic diagram of a control model for a model processing method provided in an embodiment of this 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, control points in the control model can be configured to move cyclically along their respective line segments toward the starting endpoint to achieve an infinitely looping, inwardly collapsing deformation effect in subsequent operations. For example, each control point can be configured to move from its initial position along its line segment toward the starting endpoint. Upon reaching the starting endpoint, the control point returns to the ending endpoint of the line segment, and from there continues to move along the line segment toward the starting endpoint until it reaches the starting endpoint again. Then, the control point returns to the ending endpoint of the line segment and continues moving along the line segment toward the starting endpoint, thus achieving cyclic movement of the control points along the line segment.

[0051] In one embodiment, there are several ways to configure the control point to move cyclically along the line segment toward the starting endpoint. For example, a third distance from the control point to the starting endpoint of the line segment can be obtained; the motion control parameters of the control point at the current moment can be determined based on the third distance, and the motion control parameters can be cyclically changed over time within the range of 0 to a target value; the target distance from the control point to the starting endpoint of the line segment at the current moment can be determined based on the motion control parameters; and the control point can be controlled to move cyclically based on the target distance.

[0052] 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 cycles through time from 0 to a target value, used to control the control point to move cyclically along the line segment. The target value can be a value indicating the maximum range of cyclic movement of the control point along the line segment; for example, it can be the distance between the starting and ending endpoints of the line segment, i.e., the length of the line segment. Thus, 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 be normalized, i.e., the target value can be 1. Thus, 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 the control point should reach at the next moment and the starting endpoint.

[0053] There are several ways to determine the motion control parameters of the control point at the current moment based on the third distance. For example, the line segment length and motion control function can be obtained, and the third distance can be divided by the line segment length to obtain the position ratio value corresponding to the control point. Then, the motion control parameters 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 can be a function that generates a value that cycles over time from 0 to a target value based on the current position of the control point.

[0055] For example, the length of a line segment can be mapped to a range of 0-1, where 0 represents the position of the starting endpoint and 1 represents the position of the ending endpoint. Taking a target value of 1 as an example, all control points can be traversed. For each control point, the current position of control point P can be obtained, allowing the query of the distance between control point P and the starting endpoint of the line segment (the third distance). Dividing the third distance by the line segment length yields the position ratio value t. This position ratio value t indicates the proportion of the control point's current position relative to the line segment length. For example, assuming the line segment length is 2 meters and the control point is 1 meter from the starting endpoint, the third distance is 1 meter, and the position ratio value t is 0.5. Then, the motion control function can be used to determine the motion control parameters T corresponding to the control point at the current moment based on the position ratio value t. This motion control function can be expressed as:

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

[0057] Here, `frac()` represents a function to extract the decimal part of a real number, `time` can represent a time function used to obtain the current time, `t` can represent the positional ratio corresponding to the third distance, and `T` can represent the motion control parameter. Based on the third distance, a value that cycles between 0 and 1 can be obtained, which is the motion control parameter. Therefore, based on the motion control parameter and the line segment length, the target distance from the control point to the starting endpoint of the line segment at the current moment can be calculated. For example, assuming the motion control parameter is 0.4 and the line segment length is 2 meters, the target distance can be 2 × 0.4 = 0.8, meaning that at the next moment, the distance from the control point to the starting endpoint will be 0.8 meters. This target distance value can then be assigned to the current control point to control its movement.

[0058] In one specific embodiment, for each control point, the current control point position P can be obtained, the starting endpoint position is P0, and the ending endpoint of the line segment is P1. Let P1 – P0, we can obtain a vector P0P1 pointing from P0 to P1, which has both magnitude and direction. Let P – P0, we can obtain a vector P0P pointing from P0 to the current control point P. The projection length of vector P0P onto vector P0P1 is calculated, and then the projection length is divided by the magnitude of vector P0P1, i.e., the line segment length, thereby normalizing the projection length and obtaining the position ratio value t. When t=1, it means the control point is at the end point P1 of the line segment. When t=0, it means the control point is at the beginning point 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 are obtained in a loop between 0 and 1. Based on the line segment length and the motion control parameters, the target distance between the current position of the control point and the beginning point of the line segment can be calculated, so that the control point can move to the position at the target distance from the beginning point.

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

[0060] The bounding box model can be a model that encloses the control model. The bounding box model's material can be configured based on the desired effect, making it visible and possessing a specific material. For example, when achieving a ground collapse deformation effect, the bounding box model's material can be set to the ground model's material; similarly, when achieving a collapse effect on any plane, the bounding box model's material can be set according to actual needs. The virtual camera can be a virtual camera within the virtual scene where the control model resides, and the target plane can be the plane within the bounding box model facing the virtual camera.

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

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

[0063] There are several 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. 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 can be calculated. Based on the angle information, the target plane facing the virtual camera can be determined in the plane.

[0064] Here, 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 included angle information can be the information indicating the angle between the normal of the plane and the camera direction. Thus, based on the included angle information, the target plane facing the virtual camera can be determined among multiple planes of the bounding box.

[0065] There are several ways to calculate the angle between the normal direction of the plane and the camera direction of the virtual camera based on the normal vector and the camera direction vector. 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, which is the angle 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 multiple control points to obtain the segmentation plane corresponding to each control point in the target plane.

[0067] The segmentation plane can be multiple planes obtained by dividing the target plane. Based on these multiple segmentation planes within the target plane, regions with a splitting effect can be simulated. This allows for the creation of target deformation and motion effects, such as ground fissures and collapses, spatial collapse, and object explosions.

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

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

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

[0071] The first distance can be the distance between each position point and each control point in the target plane. Each position point can be a point in the target plane, and this first distance can be calculated by obtaining 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 can be the position point assigned to the segmentation plane corresponding to the control point when the target plane is segmented.

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

[0073] In one embodiment, the segmentation indication information can be Voronoi noise, also known as cellular noise, etc. For example, each control point can be used as a seed point to divide the position points in the space corresponding to the target plane, thus obtaining Voronoi noise. This Voronoi noise can indicate the target position points in the segmented planes corresponding to each control point among the position points in the target plane. Optionally, the Voronoi noise can be a noise map, in which cell regions corresponding to each control point are distributed, and the target position points corresponding to each control point are located in the cell regions corresponding to the corresponding control points. Therefore, based on Voronoi noise, the target plane can be divided into multiple cell regions, each cell region being a segmentation plane, and each segmentation plane corresponding to a control point. The distance between any position point in each segmentation plane and its corresponding control point is less than the distance between any other control point. In this way, a target plane simulating a segmentation effect can be obtained.

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

[0075] Optionally, since the control points cyclically move within the control model, the current positions of multiple control points in the model can be acquired in real time. Based on these positions, the target plane can be dynamically segmented to obtain the segmentation plane corresponding to each control point within 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 This is another schematic diagram of the segmented plane of a model processing method provided in an embodiment of this application. Since the control points are constantly cyclically moving, the positions of the control points acquired at different times are dynamically changing. Figure 3d The dividing plane shown is Figure 3e The shown segmentation planes are different. Therefore, based on the positions of dynamically changing control points, the target plane can be segmented to obtain dynamically changing segmentation planes in the target plane.

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

[0077] At least two of the segmented planes have different movement parameters. The target deformation motion effect can be an effect used to simulate the deformation motion of an object, such as ground fissures, spatial collapse, or object explosion. The movement parameters can be parameters used to control the segmented planes, determined based on the target deformation motion effect to be achieved.

[0078] There are several ways to determine the movement parameters required for each segmented plane to achieve the target deformation motion effect. For example, the movement parameters may include the movement direction and the movement distance. A second distance between the center position of each segmented plane and the target plane can be calculated. Based on the second distance, the movement distance required for each segmented plane to achieve the target deformation motion effect can be determined, and the movement direction matching the target deformation motion effect of each segmented plane can be obtained.

[0079] The movement direction can be the direction in which the segmented plane moves, and the movement distance can be the distance the segmented plane moves. The second distance can be the distance between the center position of each segmented plane and the target plane. This second distance can be calculated by obtaining the world coordinates of the center position of the target plane and the world coordinates of the center positions of the segmented planes, or by obtaining the world coordinates of the starting endpoint in the control model and the world coordinates of the control points corresponding to the segmented planes.

[0080] There are several ways to determine the required movement distance for each segmented plane to achieve the target deformation motion effect based on the second distance, and to obtain the movement direction of each segmented plane matching the target deformation motion effect. For example, the second distance can be used as the required movement distance for each segmented plane to achieve the target deformation motion effect, and the movement direction of each segmented plane matching the target deformation motion effect can be obtained. For example, if the target deformation motion effect is an inward cyclic collapse effect, the movement direction can be upward. The closer the segmented plane is to the center of the target plane, the smaller the movement distance, and the farther the segmented plane is from the center of the target plane, the larger the movement distance. Thus, by controlling the dynamically changing segmented planes to move the corresponding movement distance in the upward direction, the target deformation motion effect of the object collapsing inward can be achieved. For example, if the target deformation motion effect is an outward explosion effect, the direction of movement can be diagonally upward. The movement direction corresponding to each segmented plane can be offset. The segmented plane that is closer to the center of the target plane moves closer to the top, while the segmented plane that is farther from the center of the target plane moves further away from the top. Also, the segmented plane that is closer to the center of the target plane moves a greater distance, while the segmented plane that is farther from the center of the target plane moves a smaller distance. Thus, by controlling the dynamically changing segmented planes to move a corresponding distance in the upward direction, the target deformation motion effect of the object exploding outward can be achieved.

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

[0082] 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 an object splitting into multiple segments and moving.

[0083] There are several 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, the movement parameters can be used to control the movement distance of each segmentation plane along the movement direction to obtain a target model with target deformation motion effects.

[0084] There are several ways to control the movement distance of each segmented plane along the movement direction according to the movement parameters to obtain a target model with target deformation motion effects. For example, according to the movement parameters, the movement distance can be used as the extrusion height to perform extrusion operation on each segmented plane in the movement direction to obtain a target model with target deformation motion effects.

[0085] The extrusion operation can be described as extending a plane along the normal direction to create a three-dimensional model with thickness. The extrusion height can be the height at which the segmented planes are extruded. For example, taking the target deformation motion effect as an inward circular collapse effect, the extrusion operation can be performed on each segmented plane in the upward direction according to the movement parameters and the movement distance as the extrusion height. Based on the segmented planes with different extrusion heights and three-dimensional effects, a target model with the target deformation motion effect can be obtained.

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

[0087] Here, the copied plane can be a plane obtained by copying the segmented plane, the initial position can be the location of the segmented plane, and the elevation can be the plane connecting the copied plane and the segmented plane, thus obtaining a 3D model corresponding to the segmented plane to more realistically simulate the deformation and motion effects of the target. Since the vertices on the copied plane have the same index as the corresponding vertices on the segmented plane, before rendering, it can be declared that the corresponding vertices on the copied plane and the segmented plane are in the same plane, thus rendering the elevation connecting the copied plane and the segmented plane.

[0088] In one embodiment, taking the target deformation motion effect as an inward circular collapse effect as an example, please refer to... Figure 4a , Figure 4a This is a schematic diagram of the target model of a model processing method provided in this application embodiment. After dividing the target plane into multiple segmented 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. Thus, the extrusion operation is performed on each segmented plane in the upward direction. Since the moving distances corresponding to the segmented planes with different distances from the center of the target plane are also different, based on the extrusion height and three-dimensional effect corresponding to each segmented plane, the inward circular collapse effect can be simulated more realistically and accurately, thereby obtaining a target model with target deformation motion effect and better effect.

[0089] Furthermore, since the control points in the control model undergo cyclical motion, the segmented plane obtained by dividing the target plane based on the moving control points also changes in real time. Therefore, the process of moving the segmented plane according to the movement parameters also changes dynamically. For example, please refer to... Figure 4b , Figure 4b This is a schematic diagram of another target model of a model processing method provided in an embodiment of this application. As can be seen, Figure 4a and Figure 4b The target models shown have distinct target deformation motion effects. Based on the control points of the cyclic motion in the control model, dynamically changing target deformation motion effects can be generated, simplifying the generation of target deformation motion effects and thus effectively improving the model processing efficiency.

[0090] In game development projects, it is often necessary to create special effects to enhance the game experience. For example, this involves processing 3D models to generate deformation and motion effects such as ground fissures and collapses. However, existing model processing methods for generating these effects are complex and difficult, resulting in low processing efficiency. Therefore, this application proposes a model processing method that can programmatically and quickly generate effects such as infinitely looping inward collapses. This allows for rapid fulfillment of such effect requirements, significantly reducing the development difficulty and production cycle of these effects.
