[0032] The following is a detailed description in conjunction with the accompanying drawings. In this embodiment, the execution subject is a terminal device as an example. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown in the accompanying drawings.
[0033] The data processing method of this embodiment obtains a target model to be moved, wherein the target model includes multiple model vertices; obtains initial vertex parameters of the model vertices, and based on the initial vertex parameters, performs physical motion simulation on the model vertices to obtain the movement positions of the model vertices; based on the initial vertex parameters, determines the reference point positions corresponding to the model vertices; if the distance between the movement position and the reference point position does not meet the safety distance condition corresponding to the reference point position, updates the movement position to obtain the target position of the model vertex that meets the safety distance condition; based on the target position of the model vertex, controls the target model to move, which can reduce the time required to simulate the effect of the model in motion.
[0034] Please refer to Figure 1 Taking a terminal as an example, this embodiment provides a data processing method. The specific process of the data processing method can be as follows: Step 101 to Step 105, wherein:
[0035] Step 101: Obtain a target model to be moved, wherein the target model includes a plurality of model vertices.
[0036] Among them, the above-mentioned target model is a model that needs to move in the virtual scene. For example, the target model can be a cloth model such as a character's clothing, a scene curtain, etc. The target model can have multiple model vertices, and the vertex positions of at least some of the model vertices change to prompt the target model to appear to move in the virtual scene.
[0037] It should be noted that, since the target model is generally driven to move by the model joints of the target model when it moves in the virtual scene, at least some of the above-mentioned multiple model vertices are located on the model joints of the target model, so that the movement position of the model parts associated with the model joints in the target model can be obtained by calculating the movement position of the model joints of the target model.
[0038] For example, if the target model is a character costume, the model joints may be clothing areas such as hands, feet, arms, etc. in the character costume.
[0039] In this embodiment, the terminal can provide a game engine to simulate and calculate the movement and collision effects of the target model in the game engine. For example, when the target model is a cloth model, the terminal can solve the real-time collision through the cloth to simulate the deformation of the cloth model when it is hit, so that the cloth model can present a more realistic physical effect in the virtual scene.
[0040] Step 102: Acquire initial vertex parameters of the model vertices, and perform physical motion simulation on the model vertices based on the initial vertex parameters to obtain motion positions of the model vertices.
[0041] The above-mentioned initial vertex parameters are used to indicate the relevant parameters of the model vertex on the target model, and the initial vertex parameters include but are not limited to the initial position, vertex normal, initial motion speed, etc. The above-mentioned initial position can be presented in the form of coordinates, the above-mentioned vertex normal can be presented in the form of a vector, and the above-mentioned vertex normal can be presented in the form of the vertical component of the vertex normal on different coordinate axes, which can be set according to the needs and are not limited here.
[0042] For example, the above vertex normal can be described as (A, B, C), where A, B, and C are the vertical components of the vertex normal on different coordinate axes, respectively.
[0043] The above-mentioned movement position refers to the position of the model vertex after movement.
[0044] In this embodiment, the terminal obtains initial vertex parameters of the model vertices, and uses the initial vertex parameters to perform physical motion simulation on the motion of the model vertices in the virtual scene to obtain the motion positions of the model vertices.
[0045] In some embodiments, since the above-mentioned initial vertex parameters may include vertex normals, the vertex normals may be used to judge the safety conditions of the calculated motion positions of the model vertices. Since the target model may be driven to move by the model joints when it moves, and at least some of the above-mentioned multiple model vertices are located on the model joints of the target model, the normals of the model vertices may be adjusted based on the model joints of the target model.
[0046] Specifically, when the above-mentioned target model includes a model joint and the above-mentioned model vertex is on the above-mentioned model joint, the above-mentioned acquisition of the initial vertex parameters of the above-mentioned model vertex may include: the terminal may generate the initial normal of the above-mentioned model vertex based on the model surface where the model vertex is located on the target model, and then the terminal may adjust the direction of the above-mentioned initial normal based on the joint position of the above-mentioned model joint to obtain the vertex normal of the above-mentioned model vertex.
[0047] Among them, the terminal can adjust the normal direction of the initial normal of the model vertex to be outward along the center of the model joint based on the center position of the model joint, so as to obtain the vertex normal of the model vertex after the direction is adjusted.
[0048] Specifically, the terminal may use a game engine or digital content creation software (Digital Content Creation, DCC) to adjust the normal direction of the initial normal.
[0049] For example, Figure 2 The vertex normals of the hair model are shown pointing outward from the center of the model joint of the hair model.
[0050] In some embodiments, the terminal may use a physical simulation method to simulate the physical motion of the model vertices, such as using a position-based dynamics (PBD) algorithm, which is a simulation algorithm based on the physical behavior and motion of the object. The principle of the PBD algorithm is to directly control the position of the particle and simulate the model motion based on at least one corresponding function that constrains the position and rotation.
[0051] Specifically, the above-mentioned initial vertex parameters include an initial position and an initial movement speed. The above-mentioned physical movement simulation of the above-mentioned model vertices based on the above-mentioned initial vertex parameters to obtain the movement position of the above-mentioned model vertices may include: the terminal may obtain the environmental parameters of the environment in which the above-mentioned target model is located, and then the terminal may attenuate the above-mentioned initial movement speed based on the above-mentioned environmental parameters to obtain the target movement speed of the above-mentioned model vertices. Finally, the terminal may simulate the movement position of the above-mentioned model vertices based on the above-mentioned initial position and the above-mentioned target movement speed.
[0052] The above environmental parameters include, but are not limited to, gravity parameters, air resistance parameters, mass parameters, position parameters of other collision bodies in the environment, etc.
[0053] Optionally, the terminal may also perform constraint calculation on the movement positions of the model vertices to further restrict the movement positions of the model vertices, thereby obtaining the final movement positions of the model vertices.
[0054] In some embodiments, the above-mentioned physical motion simulation of the above-mentioned model vertices based on the above-mentioned initial vertex parameters to obtain the motion position of the above-mentioned model vertices may include: the terminal may obtain the motion direction of the above-mentioned target model, and then the terminal may simulate the motion position of the above-mentioned model vertices based on the above-mentioned motion direction, the above-mentioned initial position and the above-mentioned target motion speed.
[0055] Step 103: Based on the initial vertex parameters, determine the reference point position corresponding to the model vertex.
[0056] In this embodiment, the terminal can obtain a reference point for judging the movement position of the model vertex based on the initial vertex parameters of the model vertex, so as to clarify whether the movement position of the model vertex is safe or whether there is an abnormal risk based on the reference point position corresponding to the reference point, that is, the movement position of the model vertex can be restricted based on the reference point position.
[0057] In some embodiments, since the above-mentioned initial vertex parameters may include an initial position, determining the reference point position corresponding to the above-mentioned model vertex based on the above-mentioned initial vertex parameters may include: using the above-mentioned initial position as the above-mentioned reference point position, thereby judging whether the moving position of the model vertex is safe based on the initial position of the model vertex, that is, clarifying whether the movement of the model vertex is safe.
[0058] In some embodiments, when the target model is cloth or other model that needs to have a binding relationship with another model, such as when the cloth model is a virtual garment, the cloth model needs to have a binding relationship with the character model. Therefore, the terminal needs to set anti-collision reference points for the model vertices to judge the model vertices based on the anti-collision reference points to avoid the model vertices from penetrating the model when moving, such as the cloth model passing through the body area of the character model when moving.
[0059] Among them, the reference point position of the anti-collision reference point of the model vertex can be inferred according to the discovery direction of the model vertex to limit the moving distance of the model vertex.
[0060] Specifically, the above-mentioned initial vertex parameters may include an initial position and a vertex normal. The above-mentioned determination of the reference point position corresponding to the above-mentioned model vertex based on the above-mentioned initial vertex parameters may include: the terminal may normalize the above-mentioned vertex normal to obtain a target normal vector, and then the terminal may determine the reference point position of the anti-collision reference point corresponding to the above-mentioned model vertex based on the above-mentioned initial position, the above-mentioned target normal vector and a preset reverse stop distance value.
[0061] The normalization is to divide a vector by its modulus (length) so that the length of the vector becomes 1. In addition, the terminal may use a normalize function to normalize the vertex normal to obtain a target normal vector.
[0062] For example, if the normal direction of the vertex normal in the world space can be described as (A, B, C), and A, B and C are the vertical components of the vertex normal on different coordinate axes, then the length of the vertex normal vector can be calculated, and then (A, B, C) can be divided by the length to obtain the normalized target normal vector to obtain a world space normal vector with a length of 1.
[0063] Among them, the above-mentioned preset stop distance value can be obtained based on the size of the anti-collision body indicated by the user for the anti-collision point reference point, and the preset safety defense distance between the anti-collision bodies. By setting the size of the anti-collision body, the user can more intuitively control and adjust the reference point position and related parameters.
[0064] The size of the anti-collision body may be the radius of the anti-collision body, the maximum distance from the center to the edge of the anti-collision body, etc., which may be specifically set according to the shape of the anti-collision body and is not limited here.
[0065] Specifically, the terminal may calculate the sum of the size of the anti-collision body and the safety defense distance as the preset backstop distance value.
[0066] For example, if the anti-collision body is set to be a sphere, the radius of the anti-collision body is Backstop Radius, and the safety defense distance is Backstop Distance, then the preset backstop distance value may be Backstop Radius+Backstop Distance.
[0067] Specifically, the above-mentioned determination of the reference point position of the anti-collision reference point corresponding to the above-mentioned model vertex based on the above-mentioned initial position, the above-mentioned target normal vector and the preset backstop distance value may include: the terminal may calculate the second product between the above-mentioned target normal vector and the above-mentioned preset backstop distance value, so as to use the difference between the above-mentioned initial position and the above-mentioned second product as the reference point position of the above-mentioned anti-collision reference point.
[0068] Exemplarily, if the initial position is set to pointA and the target normal vector is normalDirWS, then the reference point position of the anti-collision reference point may be pointA-normalDirWS*preset backstop distance value.
[0069] Step 104: If the distance between the moving position and the reference point position does not meet the safety distance condition corresponding to the reference point position, the moving position is updated to obtain the target position of the model vertex that meets the safety distance condition.
[0070] In this embodiment, the terminal determines whether the distance between the moving position of the model vertex and the reference point position obtained above meets the corresponding safety distance conditions to determine whether the moving position of the model vertex needs to be updated. That is, if the distance between the moving position of the model vertex and the reference point position obtained above meets the corresponding safety distance conditions, it means that the movement of the model vertex is safe and there is no need to update the moving position of the model vertex; if the distance between the moving position of the model vertex and the reference point position obtained above does not meet the corresponding safety distance conditions, it means that the movement of the model vertex is unsafe, so the moving position of the model vertex needs to be updated to obtain the target position of the model vertex that meets the safety distance conditions.
[0071] In some embodiments, when the above-mentioned initial position is used as the reference point position, the distance between the above-mentioned moving position and the above-mentioned reference point position does not meet the safety distance condition corresponding to the above-mentioned reference point position, which may include: the distance between the above-mentioned moving position and the above-mentioned initial position is greater than the preset target safety distance.
[0072] For example, Figure 3As shown, the initial position can be set as pointA, the moving position as pointA1, and the preset target safety distance as MaxDistance. Then, the distance between pointA and pointA1 is calculated to compare the distance between pointA and pointA1 with MaxDistance, so as to determine whether the distance between the moving position and the initial position meets the safety distance condition corresponding to the initial position. Figure 3 pointA1 is not shown.
[0073] Among them, if the distance is less than or equal to MaxDistance, it means that the distance between the above-mentioned moving position and the above-mentioned initial position meets the safety distance condition corresponding to the above-mentioned initial position; if the distance is greater than MaxDistance, it means that the distance between the above-mentioned moving position and the above-mentioned initial position does not meet the safety distance condition corresponding to the above-mentioned initial position.
[0074] The terminal may use the Distance function to calculate the distance between pointA and pointA1, that is, use Distance(pointA, pointA1) to obtain the distance between pointA and pointA1.
[0075] In some embodiments, when the reference point position of the above-mentioned anti-collision reference point is used as the reference point position, the distance between the above-mentioned motion position and the above-mentioned reference point position does not meet the safety distance condition corresponding to the above-mentioned reference point position, which may include: the distance between the above-mentioned motion position and the reference point position of the above-mentioned anti-collision reference point is less than the above-mentioned preset stop distance value.
[0076] For example, Figure 3 As shown, the motion position can be set as pointA1, the reference point position of the anti-collision reference point can be set as pointB, the preset backstop distance value is Backstop Radius+Backstop Distance, and then the distance between pointA1 and pointB is calculated to judge the distance between pointA1 and pointB with Backstop Radius+BackstopDistance, so as to clarify whether the distance between the above motion position and the reference point position of the above anti-collision reference point meets the safety distance condition corresponding to the reference point position of the above anti-collision reference point.
[0077] Among them, if the distance is less than Backstop Radius + Backstop Distance, it means that the distance between the above-mentioned moving position and the reference point position of the above-mentioned anti-collision reference point does not meet the safety distance condition corresponding to the reference point position of the above-mentioned anti-collision reference point; and if the distance is greater than or equal to Backstop Radius + Backstop Distance, it means that the distance between the above-mentioned moving position and the reference point position of the above-mentioned anti-collision reference point meets the safety distance condition corresponding to the reference point position of the above-mentioned anti-collision reference point.
[0078] The terminal may use the Distance function to calculate the distance between pointA1 and pointB, that is, use Distance(pointA1, pointB) to obtain the distance between pointA1 and pointB.
[0079] In some embodiments, the above-mentioned updating of the above-mentioned moving position to obtain the target position of the above-mentioned model vertex that meets the safety distance condition may include: the terminal may obtain the positional relationship between the above-mentioned moving position and the above-mentioned reference point position, and then the terminal may update the above-mentioned moving position based on the above-mentioned positional relationship and the above-mentioned safety distance condition to obtain the target position of the above-mentioned model vertex.
[0080] Among them, the above-mentioned position relationship can be the direction vector between the above-mentioned movement position and the above-mentioned reference point position, the distance between the above-mentioned movement position and the above-mentioned reference point position, etc., which can be set specifically according to needs and is not limited here.
[0081] In some embodiments, when the above-mentioned initial position is used as the reference point position, the above-mentioned obtaining of the positional relationship between the above-mentioned moving position and the above-mentioned reference point position may include: the terminal may obtain a first direction vector between the above-mentioned moving position and the above-mentioned initial position, and then, the terminal may normalize the above-mentioned first direction vector to obtain a normalized first target direction vector, and the above-mentioned first target direction vector is used to indicate the positional relationship between the above-mentioned moving position and the above-mentioned initial position.
[0082] The terminal may obtain the first direction vector by calculating the difference between the moving position and the initial position.
[0083] Exemplarily, the terminal may use the normalize function to normalize the first direction vector. If the initial position is set to pointA, the moving position is pointA1, and the first direction vector between pointA and pointA1 is pointA1-pointA, then normalize(pointA1-pointA) may be used to obtain the normalized first target direction vector.
[0084] In some embodiments, the above-mentioned moving position is updated based on the above-mentioned position relationship and the above-mentioned safety distance condition to obtain the target position of the above-mentioned model vertex, which may include: the terminal may calculate the first product between the above-mentioned first target direction vector and the above-mentioned preset target safety distance, and then the terminal may use the sum of the above-mentioned initial position and the above-mentioned first product as the target position of the above-mentioned model vertex, so that the target position of the model vertex can be limited to a safety range with the initial position as the center and the preset target safety distance as the radius.
[0085] Exemplarily, if the initial position is set to pointA, the first target direction vector obtained based on the normalize function is pointA1ADir, and the preset target safety distance is MaxDistance, then the target position can be pointA+pointA1Adir*MaxDistance.
[0086] In some embodiments, when the reference point position of the anti-collision reference point is used as the reference point position, the above-mentioned acquisition of the positional relationship between the above-mentioned motion position and the above-mentioned reference point position may include: the terminal may acquire a second direction vector between the above-mentioned motion position and the reference point position of the above-mentioned anti-collision reference point, and then the terminal may normalize the above-mentioned second direction vector to obtain a normalized second target direction vector, and the above-mentioned second target direction vector is used to indicate the positional relationship between the above-mentioned motion position and the reference point position of the above-mentioned anti-collision reference point.
[0087] The terminal may obtain the second direction vector by calculating the difference between the motion position and the reference point position of the anti-collision reference point.
[0088] Exemplarily, the terminal can use the normalize function to normalize the above-mentioned second direction vector. If the motion position is set to pointA1, the reference point position of the above-mentioned anti-collision reference point is pointB, and the second direction vector between pointA1 and pointB is pointA1-pointB, then normalize(pointA1-pointB) can be used to obtain the normalized second target direction vector.
[0089] In some embodiments, the above-mentioned motion position is updated based on the above-mentioned position relationship and the above-mentioned safety distance condition to obtain the target position of the above-mentioned model vertex, which may include: the terminal may calculate the third product between the above-mentioned second target direction vector and the above-mentioned preset stop distance value, and then the terminal may use the sum of the reference point position of the above-mentioned anti-collision reference point and the above-mentioned third product as the target position of the above-mentioned model vertex, so that the target position of the model vertex can be limited to outside the range with the reference point position of the anti-collision reference point as the center of the circle and the preset stop distance value as the radius.
[0090] Exemplarily, if the reference point position of the anti-collision reference point is set to pointB, the second target direction vector is pointA1BDir, and the preset backstop distance value is Backstop Radius+Backstop Distance, then the target position may be pointB+pointA1BDir*(Backstop Radius+Backstop Distance).
[0091] In some embodiments, when the initial position and the reference point position of the anti-collision reference point are both used as the reference point position, the terminal may first judge the motion position based on the initial position to determine whether to update the motion position based on the judgment result, and obtain the motion position after the first processing, which may be an updated motion position or an unupdated motion position. Then, the terminal judges the motion position after the first processing based on the reference point position of the anti-collision reference point to determine whether to continue to update the motion position after the first processing based on the judgment result, thereby obtaining the target position of the model vertex.
[0092] For example, Figure 3 As shown, Figure 3 PointA and pointB in are both reference points. Figure 3 The position in is the reference point position, and the target position must be inside the solid circle with pointA as the center and outside the solid circle with pointB as the center.
[0093] Step 105: Based on the target positions of the vertices of the model, control the target model to move.
[0094] In this embodiment, the terminal does not need to set a collision body on the model in advance. Instead, during real-time movement, the terminal limits the movement distance and position of the model vertices through safety distance conditions to determine the target position of the model vertices, thereby controlling the movement of the target model based on the target position of each model vertex.
[0095] It is understandable that by calculating the safe movement position of the model vertices to drive the movement of the target model, the relevant staff is avoided from having to operate the complex process of setting up collision bodies on the target model in advance, thereby reducing the time required to simulate the effect of the model being hit. In addition, it also avoids the situation where the collision body cannot wrap the corresponding position of the model well, such as the main movement joints of the model, and avoids the accuracy and range required for collision detection of the collision body. This embodiment can handle more complex model collision effects, avoids the time cost of setting up collision bodies and debugging, and at the same time ensures the authenticity of the scene and improves the physical effect performance and accuracy of the model in the virtual scene.
