Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0030] Embodiments of the present application provide a model special effect generation method, device, electronic device, and computer-readable storage medium.

[0031] Specifically, this embodiment will be described from the perspective of a model special effect generation device, which can be integrated into an electronic device, that is, the model special effect generation method of the embodiment of the present application can be executed by an electronic device, and optionally, the electronic device may include: a terminal device. The terminal device may be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop computer, a game console, or a personal computer (PC) and the like.

[0032] The model special effect generation method provided in the embodiment of the present application can be applied to a model special effect generation system. The model special effect generation system may include a player terminal device and a server, and the terminal may be a device including both receiving and transmitting hardware, that is, a device having receiving and transmitting hardware capable of performing two-way communication on a two-way communication link. The player terminal device and the server may perform two-way communication via a network.

[0033] Optionally, the server may be an independent server, or a server network or server cluster composed of servers, including but not limited to a computer, a network host, a single network server, a plurality of network server sets or a cloud server composed of multiple servers. The cloud server is composed of a large number of computers or network servers based on cloud computing.

[0034] 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.

[0035] The model special effects generation method of the present embodiment obtains a target object model, wherein the target object model is composed of multiple model blocks, and multiple vertices of the model blocks are configured with the same model identifier, and the model identifier is used to indicate the position of the model block; obtains the first motion control parameter of the change stage required for generating the object change special effects of the target object model, wherein the first motion control parameter is used to indicate the movement of the target object model in the corresponding change stage; based on the first motion control parameter of the change stage and the model identifier of the model block, determines the second motion control parameter of the model block in the change stage, wherein the second motion control parameters of at least two model blocks in the change stage are different; based on the second motion control parameter of the model block in the change stage, controls the vertices of the model block to move to generate the object change special effects, which can improve the efficiency of model special effects generation.

[0036] Please refer to Figure 1 Taking a terminal as an example, this embodiment provides a model special effect generation method. The specific process of the model special effect generation method can be as follows: Step 101 to Step 104, wherein:

[0037] Step 101: Acquire a target object model, wherein the target object model is composed of a plurality of model blocks, a plurality of vertices of the model blocks are configured with a same model identifier, and the model identifier is used to indicate a position of the model block.

[0038] Among them, the target object model is in a virtual scene, and the appearance and performance of the target object model can be enhanced by special effects. For example, the target object model can be changed by special effects in the virtual scene through object change special effects to enhance its effect presentation in the virtual scene and match the content in the virtual scene.

[0039] Among them, the above-mentioned object change special effects can be special effects for the changes of the target object model itself, such as a shattering special effect, that is, the target object model can express the shattering special effect through animation processes such as unstable shaking, exploding, suspension of the model block after the explosion, and retraction of the suspended model block.

[0040] In this embodiment, the terminal obtains the target object model to render the target object model accordingly to generate corresponding special effects of the target object model, and in order to be able to more accurately control the table object model to generate special effects with better effects, the terminal further processes the target object model into a plurality of model blocks, and the terminal can configure the same model identifier for the multiple vertices constituting the model block, so as to control the multiple vertices of the model block to perform unified movement, for example, the multiple vertices of the model block are uniformly subjected to scaling displacement operations or rotation operations, etc., to show the motion effect of the model block.

[0041] It can be understood that since each vertex is calculated in parallel in the shader, it is not known which vertices belong to a model block. Therefore, in this embodiment, the terminal needs to indicate the model block to which the vertex belongs through the model identifier, that is, the above-mentioned model identifier can be used to identify the model block, that is, by associating the model identifier with the vertex, such as storing the identification information on the vertex to indicate which model block the vertex belongs to, so as to control the unified movement of multiple vertices belonging to the same model block, so as to realize the overall movement of the model block.

[0042] The target object model may refer to a complete representation of a virtual object, and the vertices are three-dimensional points constituting the target object model. The vertices may be connected together to form triangles or other shapes, and then these triangles or other shapes may be combined together to form the target object model.

[0043] Specifically, the terminal can use existing nodes in a visual shader editor ShaderGraph in the Unity engine to control the unified movement of multiple vertices of the model block. For example, the "Rotate About Axis" node can be used to control the unified rotation operation of multiple vertices based on the same model identifier configured for multiple vertices.

[0044] Specifically, in order to process the target object model as being composed of multiple model blocks, the initial target object model that has not been cut into multiple model blocks can be fragmented, and the terminal can use the nodes for Boolean operations in the preset three-dimensional computer graphics software (Houdini software), for example, using the "Boolean" node to cut the target object model, and the cut target object model has corresponding connection information. Through the corresponding connection information of the cut target object model, each model block can be separated, and then the corresponding model identifiers can be set on multiple vertices of the model block.

[0045] Among them, the above-mentioned node is a set of logical encapsulations, which consists of input, parameters, internal logic, output and other links. Its function is to process the input and output the corresponding result; the above-mentioned Houdini software is a product designed based on the node mode; the above-mentioned shader can be used in 3D rendering technology to process how the surface interacts with light to form the lighting effect of the model. In this embodiment, the above-mentioned shader can be a vertex shader to process vertex movement.

[0046] Specifically, since the positions of different model blocks in the target object model are different, the model identifiers that can indicate the module positions are also different. The terminal can establish a mapping relationship between the positions of the model blocks and the model identifiers to determine the corresponding model identifiers based on the positions of the model blocks; the terminal can also directly use the positions of the model blocks as the model identifiers, for example, using the center position of the center point of the model block as the model identifier. It can be understood that since there are other center positions later, in this embodiment, the center position of the center point of the model block is recorded as the first center position.

[0047] It can be understood that, in addition to being independently set in the virtual scene and performing corresponding object change effects based on the actions of the target object model in the virtual scene, the target object model can also be associated with other virtual objects. For example, the above-mentioned target object model is set on a virtual object in the virtual scene. Since the target object model is associated with other virtual objects, in order to improve the performance of the virtual scene, the animation actions of the virtual objects associated with the target object model in the virtual scene can affect the object change effects of the target object model, that is, different animation actions correspond to different object change effects of the target object model, and the different ways of the object change effects can be different in the content design of the animation process, in the presentation duration of the animation process, etc., which can be set specifically according to needs and are not limited here.

[0048] For example, the virtual object may be a firearm, and the target object model may be a gemstone model disposed on the firearm, such as Figure 2 As shown, the gem model can be composed of 50 model blocks. If the current firearm design is set to have three animation actions, namely inspection action, reloading action, and empty chamber reloading action, since these three actions have different action performances, different animation effects are required to correspond to them. Therefore, the gem model can be controlled to present different broken special effects.

[0049] Then, if Figure 3 As shown, the position of the center point of each model block in the gemstone model, that is, the first center position, can be calculated. Figure 3 The position indicated by the middle arrow is recorded as pivot, which is the first center position. It can be understood that for ease of viewing, Figure 3 Only the pivots of three model blocks are indicated, and the other model blocks are also set with pivots.

[0050] Furthermore, if Figure 4 As shown, Figure 4 When no pivot is set at the vertex of the gemstone model block in the upper area, the reduction of the gemstone model is for the entire gemstone model, that is, the gemstone model is reduced as a whole. Figure 4 When each model block of the gem model in the lower area is set with a pivot, the reduction of the gem model is targeted at the model blocks of the gem model, that is, the model blocks of the gem model are reduced separately.

[0051] Step 102: Obtain a first motion control parameter of a change phase required for generating an object change special effect of the target object model, wherein the first motion control parameter is used to indicate the motion of the target object model in a corresponding change phase.

[0052] It can be understood that the object change special effects of the above-mentioned target object model can be composed of one or at least two different animation processes. For example, for the shattering special effect, the shattering special effect can be expressed through animation processes such as unstable shaking, exploding, suspension of the model block after the explosion, and retraction of the suspended model block.

[0053] In this regard, in order to accurately present the different animation processes of the object change effects of the target object model, the terminal can set a corresponding change stage for each animation process. In order to be able to present the corresponding animation process in a change stage of the object change effect, it is necessary to set motion control parameters that match the animation process for each change stage required for the object change effect. It can be understood that since there are other motion control parameters later, in this embodiment, the motion control parameters of the target object model that match the change stage are recorded as the first motion control parameters.

[0054] In this embodiment, the terminal controls the target object model to move in the virtual scene based on the first motion control parameter preset or generated in real time for the target object model, and the motion includes but is not limited to a displacement operation or a rotation operation.

[0055] Specifically, the first motion control parameter may be a description of the motion of the target object model in the corresponding change stage. Exemplarily, setting the object change special effect of the target object model requires four change stages, namely, TimeInAnim2, TimeInAnim3 and TimeInAnim4. The TimeInAnim1 corresponds to parameter 1 indicating that the current target object model maintains its status quo in the change stage; the TimeInAnim2 (recorded as the explosion stage) corresponds to parameter 2 indicating that the current target object model explodes in the change stage, that is, the model block of the target object model is controlled to move outward; the TimeInAnim3 corresponds to parameter 3 indicating that the current target object model is suspended in the change stage, that is, the displacement is maintained for a period of time, which can cause the model block to have a slight outward expansion movement; the TimeInAnim4 (recorded as the closing stage) corresponds to parameter 4 indicating that the current target object model rotates and retracts in the change stage, for example, while rotating, the model block of the target object model is controlled to move inward.

[0056] The outward movement of the model block means that the model block moves in a direction away from the center position of the target object model, while the inward movement of the model block means that the model block moves in a direction close to the center position of the target object model.

[0057] Specifically, the above-mentioned first motion control parameter can also be the initial position change of the target object model in the corresponding change stage, and the initial position change includes but is not limited to the initial displacement change and the initial rotation degree change. The initial position change of the target object model may include: it can be the total change from the starting position to the end position in the change stage, such as the total displacement required to be moved, and the total rotation degree required to be rotated; or, it can also be the change corresponding to each node in the change stage, such as the displacement value required to be displaced at the node, and the rotation degree required to be rotated at the node; or, it can also be a parameter change curve matching the change stage, the horizontal axis of the parameter change curve corresponds to the change stage, and the vertical axis of the parameter change curve corresponds to the total change or the change of a node, which can be set according to needs and is not limited here.

[0058] For example, based on the four change stages in the above example, namely, TimeInAnim1, TimeInAnim2, TimeInAnim3 and TimeInAnim4, corresponding parameter change curves can be designed for TimeInAnim1, TimeInAnim2, TimeInAnim3 and TimeInAnim4 respectively, so as to obtain a total parameter change curve corresponding to the object change special effect, such as Figure 5 As shown, the total parameter change curve includes the total displacement change curve ( Figure 5 The curve corresponding to the displacement) and the total curve of the rotation degree change ( Figure 5 The curve corresponding to the rotation in ).

[0059] from Figure 5 As can be seen, Figure 5 The 0 to 1 in the above is the total change required for the object change effect composed of each change stage. Different change stages have different proportions in the total change stage, and the corresponding animation duration required in the corresponding change stage is also different. In TimeInAnim1, the target object model remains unchanged to form a preheating state; in TimeInAnim2, the target object model explodes, and the model block needs to move outward without rotation, so only the displacement of the corresponding curve part changes; in TimeInAnim3, the target object model needs to show that the model block is suspended and slightly expanded, so there is a little displacement, which prompts the model block to have a slight outward expansion movement, accompanied by rapid rotation; in TimeInAnim4, the target object model needs to be restored, that is, the target object model needs to be rotated and retracted, so it needs to be based on the displacement of moving inward. It should be noted that the rotation degree of the model block during rotation has been restored from 0 to 360, while the displacement needs to be restored from 0 to 1 and then to 0.

[0060] In some embodiments, when the target object model is set on a virtual object in a virtual scene, since the animation action of the virtual object associated with the target object model in the virtual scene can affect the object change effect of the target object model, the acquisition of the first motion control parameter of the change stage required for generating the object change effect of the target object model may include: the terminal may acquire the animation action of the virtual object in the virtual scene; then, the terminal may determine the first motion control parameter of the change stage based on the animation action of the virtual object to achieve different animation actions of the virtual object to affect the object change effect of the target object model, such as under different animation actions, the first motion control parameter of some change stages is set to empty, and under different animation actions, the first motion control parameters of some change stages are different, and under different animation actions, the proportion of some change stages in all change stages is different, etc. The specific setting can be made according to the needs and is not limited here.

[0061] Step 103, based on the first motion control parameters of the above-mentioned change stage and the model identification of the above-mentioned model block, determine the second motion control parameters of the above-mentioned model block in the above-mentioned change stage, wherein the second motion control parameters of at least two model blocks in the above-mentioned change stage are different.

[0062] In this embodiment, the terminal can use the first motion control parameters of each change stage to clarify the movement of the target object model in different change stages, and the terminal can use the model identifier of each model block to clarify the position of each model block during movement, thereby finally determining the parameters used to indicate the movement mode of each model block in each change stage, that is, the above-mentioned second motion control parameters, so that the terminal can control the movement of the corresponding model block based on the second motion control parameters. The second motion control parameters can be stored in the vertices corresponding to the model blocks, or can be stored in a preset storage space in association with the model blocks. The specific settings can be made according to needs and are not limited here.

[0063] Among them, the above-mentioned second motion control parameter includes position change information, which is used to indicate the position change of the model block in the corresponding change stage, such as the change of displacement, and the change of rotation angle. Among them, the above-mentioned position change information includes the position change direction and the position change amount. The position change direction is used to indicate the direction based on which the model block changes its position, such as the target displacement direction when displacing, and the target rotation direction axis when rotating. The position change amount includes but is not limited to the displacement change amount and the rotation degree change amount.

[0064] Specifically, the position change of the above-mentioned model block may include: it may be the total change from the starting position to the ending position in the change stage, such as the displacement change is the total displacement amount to be moved, and the total rotation degree to be rotated; or, it may be the change corresponding to each node in the change stage, such as the displacement value to be displaced under the node, and the rotation degree to be rotated under the node; or, it may be a parameter change curve matching the change stage, the horizontal axis of the parameter change curve corresponds to the change stage, and the vertical axis of the parameter change curve corresponds to the total change or the change of a node, which can be set according to needs and is not limited here.

[0065] In some embodiments, the above-mentioned model identifier is used to indicate the first center position of the above-mentioned model block. It can be understood that since the model block needs to move in the virtual scene to meet the model change special effects, its first center position needs to change with the movement of the model block, that is, the above-mentioned first center position changes with the above-mentioned position change information.

[0066] Specifically, the above-mentioned determination of the second motion control parameter of the above-mentioned model block in the above-mentioned change stage based on the first motion control parameter of the above-mentioned change stage and the model identification of the above-mentioned model block may include: determining the position change amount of the above-mentioned model block in the above-mentioned change stage based on the first motion control parameter of the above-mentioned change stage; determining the position change direction of the above-mentioned model block in the above-mentioned change stage based on the first center position of the above-mentioned model block.

[0067] Among them, the initial position change amount in the first motion control parameter of the above-mentioned change stage can be directly used as the position change amount of the above-mentioned model block in the corresponding change stage. For example, the total change amount from the starting position to the ending position of the target object model in the change stage is used as the total change amount from the starting position to the ending position of the model block in the change stage. Then, when controlling the movement of the model block, the position change amount and the model identification of the model block can be used to control the movement of each model vertex with the same model identification based on the position change amount. Alternatively, the initial position change amount in the first motion control parameter of the above-mentioned change stage can be reprocessed (such as random processing) to update the position change amount to obtain the position change amount of the above-mentioned model block in the corresponding change stage.

[0068] In some embodiments, the above-mentioned position change direction includes a target displacement direction. The above-mentioned determination of the position change direction of the above-mentioned model block in the above-mentioned change stage based on the first center position of the above-mentioned model block may include: the terminal may obtain the second center position of the above-mentioned target object model, to determine the target displacement direction of the above-mentioned model block in the above-mentioned change stage based on the above-mentioned first center position and the above-mentioned second center position, thereby determining the target displacement direction of the model block in different change stages of the target object model through the relative position of the model block and the target object model, such as the model block may move outward, and the model block may also move inward.

[0069] Specifically, the above-mentioned object change special effects include a shattering special effect, the above-mentioned change stage includes an explosion stage and a closing stage, and the above-mentioned determination of the target displacement direction of the above-mentioned model block in the above-mentioned change stage based on the above-mentioned first center position and the above-mentioned second center position may include: calculating the first difference vector between the above-mentioned first center position and the above-mentioned second center position, and using the above-mentioned first difference vector as the target displacement direction of the above-mentioned model block in the above-mentioned explosion stage, and at this time the target displacement direction is the direction of outward movement.

[0070] Then, the second difference vector between the second center position and the first center position can be calculated, or a negative value can be assigned to the first difference vector to obtain the second difference vector, so that the second difference vector can be used as the target displacement direction of the model block in the closing stage, and the target displacement direction is the direction of inward movement.

[0071] Exemplarily, the first center position of the model block is set to C, the second center position of the target object model is set to CT, the difference vector obtained by subtracting CT from C is used as the first difference vector, and the difference vector obtained by subtracting C from CT is used as the second difference vector.

[0072] In some embodiments, after determining the target displacement direction of the above-mentioned model block in the above-mentioned change stage, the target displacement direction can also be assigned randomness to enhance the displacement effect of the model block in the object change special effects, that is, it can include: the terminal can assign a first random value to the coordinate value of the above-mentioned first center position on each coordinate axis, respectively, to obtain the random displacement direction of the above-mentioned model block, and then, the terminal can update the above-mentioned target displacement direction based on the above-mentioned random displacement direction to obtain an updated target displacement direction.

[0073] Specifically, an interpolation function, such as a lerp function, can be introduced to interpolate the latest displacement direction from the target displacement direction and the random displacement direction according to the difference variable set by the user, so as to update the target displacement direction, that is, replace the target displacement direction with the latest displacement direction, and the latest displacement direction is the updated target displacement direction.

[0074] Exemplarily, the target displacement direction is set to N, and N is randomly processed by the random function Rand function, that is, by RandN = (rand(Nx), rand(Ny), rand(Nz)), so as to assign a first random value to the coordinate value of the above-mentioned first center position on each coordinate axis, and obtain the random displacement direction RandN of the above-mentioned model block.

[0075] Then, the lerp function is used to interpolate between RandN and N to control the degree of randomness, that is, FinalN=lerp(N,RandN,randScale), where FinalN is the updated target displacement direction, and randScale is the difference variable set by the user, that is, randScale indicates whether it tends to be A or B. If randScale is 0, FinalN is equal to N, if randScale is 1, FinalN is equal to RandN, and if randScale is an intermediate value between 0 and 1, FinalN is equal to the interpolation between N and RandN, that is, a transition is performed.

[0076] In some embodiments, the above-mentioned first motion control parameter includes an initial displacement change, the above-mentioned position change includes a target displacement change, and the above-mentioned first motion control parameter based on the above-mentioned change stage determines the position change of the above-mentioned model block in the above-mentioned change stage, which may include: the terminal may generate a second random value of the above-mentioned model block based on the first center position of the above-mentioned model block, and then the terminal may update the initial displacement value corresponding to the above-mentioned first center position in the above-mentioned initial displacement change based on the above-mentioned second random value, such as calculating the product between the second random value and the initial displacement value to obtain an updated displacement value, wherein the above-mentioned updated displacement value is used to constitute the above-mentioned target displacement change.

[0077] Specifically, a pseudo-random function can be designed to obtain the second random value corresponding to each model block, that is, a set of unpredictable values ​​is calculated through the decimal part of the trigonometric function, that is, the second random value RandValue = frac(sin(C)*100) is set. Among them, C is the first center position, sin(C) is used to obtain an infinite non-repeating decimal, and by calculating the product of sin(C) and 100, and then taking the decimal part through the frac function, an irregular value between 0 and 1 can be obtained as the second random value, so that each model block has a different degree of explosion, which looks more natural.

[0078] In addition, the displacement change degree of the model block can also be controlled by the displacement variable set by the user. For example, if the displacement change degree is relatively large, this displacement variable is set greater than 1, and the product of the displacement variable and the initial displacement value is used as the updated displacement value, then the displacement value will be relatively large; if the displacement change degree is relatively small, then this displacement variable can be set less than 1, and the product of the displacement variable and the initial displacement value is used as the updated displacement value, then the displacement value will be relatively small.

[0079] In some embodiments, the above-mentioned position change direction includes a target rotation direction axis, and the above-mentioned determination of the position change direction of the above-mentioned model block in the above-mentioned change stage based on the first center position of the above-mentioned model block may include: the terminal may generate a third random value of the above-mentioned model block based on the first center position of the above-mentioned model block; then, the terminal may generate a target rotation vector based on the above-mentioned third random value and the normal vector at the first center position of the above-mentioned model block, wherein the above-mentioned target rotation vector serves as the above-mentioned target rotation direction axis.

[0080] Alternatively, the terminal may also directly use the normal vector at the first center position of the above model block as the target rotation vector. Alternatively, the terminal may also use the vector corresponding to the generated third random value as the target rotation vector, which may be set according to the requirements and is not limited here.

[0081] In some embodiments, the above-mentioned position change also includes a target rotation change. The processing method of the target rotation change can refer to the target displacement change.

[0082] Step 104: Based on the second motion control parameter of the model block in the change phase, control the vertices of the model block to move, so as to generate the object change effect.

[0083] In this embodiment, the terminal can control the movement of the vertices of each model block based on the second motion control parameters corresponding to each model block in each change stage. For example, based on the position change amount in the second motion control parameters and the model identifier of a model block, the terminal can control the movement of each model vertex with the same model identifier based on the position change amount to generate object change special effects, thereby reducing performance consumption and improving the efficiency of model special effects generation.

[0084] Among them, the second motion control parameter of the model block can directly or indirectly control the parameters of the vertex movement. For example, the vertex can be directly controlled to perform corresponding movement through the information in the second motion control parameter. For example, the second motion control parameter needs to be processed to control the vertex to perform corresponding movement according to the processed information.

[0085] It can be understood that the above-mentioned second motion control parameters can be stored in the vertices so that the information required to restore the vertex motion can be calculated by obtaining the parameters from the vertices. The second motion control parameters can also be stored in the storage space associated with the model block so that they can be obtained from the corresponding storage space when needed.

[0086] In some embodiments, the above-mentioned position change may include a target rotation change. The above-mentioned second motion control parameter of the above-mentioned model block in the above-mentioned change stage controls the movement of the vertices of the above-mentioned model block, which may include: the terminal may determine the target rotation degree corresponding to the above-mentioned first center position in the above-mentioned target rotation change; then, the terminal may control the vertices of the above-mentioned model block to rotate the above-mentioned target rotation degree around the above-mentioned target rotation direction axis.

[0087] In some embodiments, based on the above Figure 5 It can be seen that each change stage has a different proportion in the total change stage, and the total change stage can be represented by 0 to 1. Therefore, the above-mentioned second motion control parameter in the above-mentioned change stage includes a third motion control parameter corresponding to at least two positions. The above-mentioned second motion control parameter of the above-mentioned model block in the above-mentioned change stage controls the movement of the vertices of the above-mentioned model block to generate the above-mentioned object change special effect, including: the terminal can obtain the animation generation progress of the above-mentioned object change special effect to clarify which change stage the animation generation progress is in the total change stage, and which position the animation generation progress is currently in in the corresponding change stage. The current position reached by the animation generation progress can be used as the target generation position.

[0088] Then, the terminal can determine the third motion control parameter of the model block at the target generation position corresponding to the animation generation progress from the second motion control parameter of the model block in the above-mentioned change stage, and control the movement of the vertices of the model block at the above-mentioned target generation position based on the third motion control parameter of the model block to generate the above-mentioned object change special effect.

[0089] Specifically, the above-mentioned change stages include at least two, the above-mentioned second motion control parameters include position change information, and the above-mentioned third motion control parameters of the above-mentioned model block at the target generation position corresponding to the above-mentioned animation generation progress are determined from the second motion control parameters of the above-mentioned model block in the above-mentioned change stage, including: the terminal can determine the target change stage corresponding to the above-mentioned animation generation progress from at least two change stages; then, the terminal can interpolate the position change information of the above-mentioned model block in the above-mentioned target change stage based on the above-mentioned target generation position in the above-mentioned target change stage, and obtain the target position change information of the above-mentioned model block at the above-mentioned target generation position, wherein the above-mentioned target position change information is used as the above-mentioned third motion control parameter.

[0090] For example, based on the four change stages in the above example, namely, TimeInAnim1, TimeInAnim2, TimeInAnim3 and TimeInAnim4, as Figure 6 As shown, the terminal may further introduce a parameter TimeInAnim, which represents the animation generation progress, that is, this parameter represents the progress of the overall action and is reasonably shrunk to [0,1]. 0 represents the beginning of the animation, 1 represents the end of the animation, and the sum of the proportions of TimeInAnim1, TimeInAnim2, TimeInAnim3 and TimeInAnim4 in the total change stage is 1.

[0091] Then, the running time of TimeInAnim1 is equal to the total running time of TimeInAnim, and the running time of TimeInAnim2 is TimeInAnim-TimeInAnim1, and the same is true for TimeInAnim3 and TimeInAnim4.

[0092] from Figure 6It can be seen that TimeInAnim is currently in TimeInAnim2, so the relative position of the target generation position in the target change stage can be obtained by the function Clamp(TimeInAnim-TimeInAnim1,0,TimeInAnim2) / TimeInAnim2, so as to interpolate the position change information of the model block in the target change stage based on the relative position, obtain the position change information corresponding to the relative position, and record it as the target position change information corresponding to the target generation position.

[0093] Among them, the Clamp function can limit the value of TimeInAnim-TimeInAnim1 to between 0 and TimeInAnim2. For example, if TimeInAnim-TimeInAnim1 is greater than TimeInAnim2, the Clamp function can return the value of TimeInAnim2. When TimeInAnim has not yet entered this change stage, that is, TimeInAnim-TimeInAnim1<=0, this value will be taken as 0, indicating that the duration of the second animation is 0. Finally, divide this value by TimeInAnim2, and the final value can be mapped between 0-1 for easy calculation.

[0094] Furthermore, if Figure 7 As shown, as TimeInAnim progresses, the displacements and rotations corresponding to the four stages can be combined. Figure 7 The four areas in the diagram correspond to the animation actions respectively, among which, Figure 7 , the first area corresponds to TimeInAnim1, the second area corresponds to TimeInAnim2, the third area corresponds to TimeInAnim3, and the fourth area corresponds to TimeInAnim4.

[0095] It can be understood that, based on the second motion control parameters of each model block in each change stage, the vertices of each model block are controlled to move to generate the object change special effect. It is necessary to configure a total duration for the total change stage, and then determine the animation duration of each change stage according to the proportion of each change stage in the total change stage. Finally, based on the second motion control parameters of each model block in each change stage and the animation duration corresponding to each change stage, the vertices of each model block are controlled to move to generate the object change special effect, so as to set parameters without a timeline to achieve the object change special effect, so that different users do not need to spend a lot of time adjusting the parameters when setting the time for different time requirements in different change stages of the object change special effect.

[0096] From the above content, it can be seen that by obtaining a target object model composed of multiple model blocks, and then obtaining the first motion control parameter of the change stage required for generating the object change special effect of the above target object model, which can indicate the movement of the above target object model in the corresponding change stage, based on the first motion control parameter of the above change stage and the model identification of the above model block, the second motion control parameter of the above model block in the above change stage is determined, and the second motion control parameters of at least two model blocks are different. Finally, based on the second motion control parameter of the above model block in the above change stage, the vertices of the above model block are controlled to move to generate the above object change special effect, so as to obtain the motion control parameters corresponding to the model blocks required for generating the object change special effect of the target object model, and to control the movement of the vertices of each model block separately, thereby avoiding the computing performance consumed by controlling the movements of multiple bones, so as to improve the efficiency of model special effect generation.
