[0009] This disclosure provides a method, apparatus, and electronic device for processing model animation. The method involves acquiring an initial model animation and copying it to obtain a first model animation. The initial model animation includes a target model, and the initial model animation is a movement animation of the target model moving from a first position point to a second position point.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0018] In current model animation production, editing of animation resources, especially motion capture resources, is often required. The animation captured by motion capture actors is static and usually does not meet requirements, necessitating editing by animators in relevant software. Related technologies typically involve processing animation resources by segmenting, adjusting orientation, and manually keyframing to solve problems such as footstep drift, which is very time-consuming and labor-intensive, resulting in low animation production efficiency. Therefore, this disclosure provides a method, apparatus, and electronic device for processing model animation. This technology can be applied to devices with animation editing capabilities, and is particularly applicable to the production of motion capture resources.

[0019] To facilitate understanding of this embodiment, a method for processing model animation disclosed in this disclosure will first be described in detail, such as... Figure 1 As shown, the method includes the following steps:

[0020] Step S102: Obtain the initial model animation and copy the initial model animation to obtain the first model animation; the initial model animation includes the target model, and the initial model animation is the movement animation of the target model from the first position point to the second position point;

[0021] The aforementioned initial model animation typically refers to animation generated in specific software, such as skeletal animation generated in Maya or 3ds Max, or skeletal animation captured by motion capture actors. The target model can be a virtual character model, such as a human figure or animal model. The initial model animation could be a movement animation of a human model walking from a first position point to a second position point, running from a first position point to a second position point, or jumping from a first position point to a second position point, etc.

[0022] Optionally, in response to an upload command for the initial model animation, the initial model animation can be retrieved. For example, an animation upload control can be displayed in the graphical user interface provided by the target application running on the terminal device. In response to a trigger operation on the animation upload control, multiple model animations to be selected can be displayed. In response to a selection operation for the initial model animation, the initial model animation can be retrieved.

[0023] To modify animations without loss of quality, the initial model animation is typically not modified. Therefore, the initial model animation is copied to obtain the first model animation. Optionally, a new animation layer is created, and the first model animation is displayed on the new animation layer. Specifically, the initial model animation is obtained and displayed on the first animation layer; a second animation layer is created, and the first model animation is displayed on the second animation layer.

[0024] Optionally, after obtaining the initial model animation, the skeletal data in the initial model animation is traversed, and the first model animation is obtained by copying the skeletal data. The initial model animation is the same as the first model animation.

[0025] Optionally, the target model mentioned above includes at least one model skeleton.

[0026] Step S104: In response to the adjustment operation of the target model in the first model animation, the movement endpoint of the target model is adjusted from the second position point to the third position point; wherein, the adjusted first model animation is the movement animation of the target model from the first position point to the third position point, and the target model exhibits a smooth movement phenomenon when the bottom of the model is touching the ground during the movement.

[0027] Optionally, the first change between the third position point and the first position point is greater than the second change between the second position point and the first position point, wherein the first change includes at least the first target change between the third position point and the first position point, and the first rotation data of the target model between the third position point and the first position point; similarly, the second change includes at least the second target change between the second position point and the first position point, and the second rotation data of the target model between the second position point and the first position point.

[0028] Optionally, after adjusting the target model's movement endpoint from the second position point to the third position point, the system will automatically adjust the first model animation based on the first and third position points, so that the target model in the first model animation moves from the first position point to the third position point.

[0029] Optionally, a specified amount of change can be added to the initial change amount of each animation frame in the initial model animation. This specified amount of change is the ratio of the third change amount between the third position point and the second position point to the total number of animation frames in the first model animation. In this adjustment method, if the target model is stationary or its bottom is touching the ground in some animation frames, increasing the change amount of the target model (such as increasing the movement distance) will cause a smooth movement phenomenon when the bottom of the target model is touching the ground during the movement.

[0030] Optionally, in response to a drag operation on the target model located at the second position point, the target model is dragged to the third position point, and the control adjusts the endpoint of the target model's movement from the second position point to the third position point. Typically, the target model is configured with a controller to facilitate user adjustments. Specifically, in response to a drag operation on the first controller of the target model located at the second position point, the target model is dragged to the third position point.

[0031] The smooth movement phenomenon when the bottom of the model is touching the ground refers to the displacement of the bottom of the model relative to the ground when the bottom of the model is touching the ground, commonly known as the sliding phenomenon.

[0032] Step S106: In response to the elimination instruction for smooth movement phenomenon, determine the target animation frame in the initial model animation, wherein the target model in the target animation frame is in a non-static state.

[0033] Optionally, in response to a triggering operation of a smoothing elimination control for a graphical user interface display, an elimination instruction is generated for the smoothing motion phenomenon present in the adjusted first model animation.

[0034] Optionally, the target model is a model skeleton. The amount of change in each animation frame is determined from the initial model animation, and the corresponding animation frame is determined to be the target animation frame based on this amount of change. For example, if the amount of change in the current animation frame is not zero, then the target model in the current animation frame is determined to be in a non-static state, and the current animation frame is determined to be the target animation frame.

[0035] Optionally, the target model includes multiple model skeletons. The amount of change of each model skeleton in each animation frame is determined from the initial model animation, and the corresponding animation frame is determined to be the target animation frame based on the amount of change. For example, if there are model skeletons in the current animation frame with a non-zero amount of change, then the target model in the current animation frame is determined to be in a non-static state, and the current animation frame is determined to be the target animation frame.

[0036] Step S108: Determine the offset of the target model in the target animation frame based on the target change amount between the second position point and the third position point;

[0037] Optionally, the target model is a model skeleton. The ratio of the target change to the total number of frames in the target animation is calculated, and this ratio is determined as the offset of the target model in the target animation frame. Alternatively, the ratio of the change of the target model in the target animation frame to the total change of the target model in the initial model animation is calculated to obtain the ratio of the target animation frame. The product of the target change and this ratio of the target animation frame is then calculated to obtain the offset of the target model in the target animation frame.

[0038] Optionally, the target model includes multiple model bones, and the offset of the model bone in the target animation frame is determined based on the target change amount of each model bone between the second position point and the third position point.

[0039] Step S110: Control the change amount of the target model in the target animation frame to increase the offset to obtain the target model animation; wherein, the target model animation is the movement animation of the target model from the first position point to the third position point, and there is no smooth movement phenomenon when the bottom of the target model is touching the ground during the movement.

[0040] Specifically, by controlling the amount of change of the target model in the target animation frame and increasing the offset of the target model in the target animation frame, the target model animation is obtained.

[0041] Optionally, the target model is a model skeleton. The displacement change of the target model in the target animation frame is increased by the displacement offset of the target model in the target animation frame, and the rotation change of the target model in the target animation frame is increased by the rotation offset to obtain the target model animation.

[0042] Optionally, the target model includes multiple model bones, and the amount of change of the model bones in the target animation frame is increased by increasing the offset of the model bone in the target animation frame. For example, if the displacement change of the first model bone (i.e., the waist bone) in the target animation frame is 1 and the rotation change is 0, and the displacement offset of the first model bone in the target animation frame determined in the above steps is 0.1 and the rotation change is 0, then by increasing the displacement change of 1 of the first model bone in the target animation frame by 0.1, the resulting displacement change of the first model bone in the target animation frame is 1.1 and the rotation change is 0.

[0043] It should be noted that the amount of change of the target model in the target animation frame is increased by the offset. Usually, the target model is offset only after it leaves the ground. When the target model is in the air, there will be no slippage phenomenon when the offset occurs.

[0044] The aforementioned changes include at least displacement and rotation; similarly, the aforementioned offsets include at least displacement and rotation. The changes can also refer to changes in the skeleton of the target model.

[0045] This disclosure provides a method for processing model animation, which involves obtaining an initial model animation and copying it to obtain a first model animation. The initial model animation includes a target model, and the initial model animation is a movement animation of the target model moving from a first position point to a second position point. In response to an adjustment operation on the target model in the first model animation, the endpoint of the target model's movement is adjusted from the second position point to a third position point. The adjusted first model animation is a movement animation of the target model moving from the first position point to the third position point, and the target model exhibits a smooth movement phenomenon when its bottom is on the ground during the movement. In response to an instruction to eliminate the smooth movement phenomenon, a target animation frame is determined in the initial model animation, wherein the target model in the target animation frame is in a non-static state. Based on the target change amount of the target model between the second and third position points, the offset of the target model in the target animation frame is determined. The target model animation is obtained by controlling the change amount of the target model in the target animation frame to increase the offset. The target model animation is a movement animation of the target model moving from the first position point to the third position point, and the target model does not exhibit a smooth movement phenomenon when its bottom is on the ground during the movement. This method automates the process of handling slippage issues that occur after model animation adjustments with a single click, eliminating the need for manual editing to resolve slippage problems, thus reducing time and labor costs and improving animation production efficiency.

[0046] The target model mentioned above includes multiple model bones. The steps for determining the target animation frame in the initial model animation include: determining the animation frame of the initial model animation; for each model bone in the animation frame, calculating the amount of change between the model bone and the model bone in the adjacent previous animation frame to obtain the amount of change of the model bone; if there is a model bone in the animation frame with a non-zero amount of change, the animation frame is determined as the target animation frame.

[0047] Optionally, a first difference between the displacement data of the model skeleton and the displacement data of the model skeleton in the adjacent previous animation frame, and a second difference between the rotational displacement data of the model skeleton and the rotational displacement data of the model skeleton in the adjacent previous animation frame are calculated, and the first difference and the second difference are determined as the change in the model skeleton. Wherein, the first difference is the change in displacement of the model skeleton, and the second difference is the change in rotation of the model skeleton.

[0048] For example, the target model includes a first model skeleton and a second model skeleton; for the first model skeleton in the animation frame, the change between the first model skeleton and the second model skeleton in the adjacent previous animation frame is calculated to obtain the change of the first model skeleton; the change between the second model skeleton and the second model skeleton in the adjacent previous animation frame is calculated to obtain the change of the second model skeleton.

[0049] If all model bones in an animation frame are zero, the target model in that animation frame is determined to be in a static state. If there are model bones in an animation frame with non-zero changes, the animation frame is determined to be the target animation frame.

[0050] For example, if the changes in the first model's skeleton and the changes in the second model's skeleton are both zero, the animation frame is determined not to be the target animation frame. Conversely, if the changes in the first model's skeleton and / or the second model's skeleton are not zero, the animation frame is determined to be the target animation frame.

[0051] By determining whether the change in the model skeleton in each animation frame of the initial model animation is zero, it is determined whether the animation frame is in a non-static state, and thus the target animation frame is determined.

[0052] One possible implementation of the above steps for determining the offset of the target model in the target animation frame based on the target model's change between the second and third position points is as follows:

[0053] Based on the target change of the model skeleton in the target model between the second and third position points, determine the offset of the model skeleton in the target animation frame.

[0054] Optionally, for each model bone in the target model, determine the position and rotation data of the model bone at the second position point in the initial model animation, and determine the position and rotation data of the model bone at the third position point in the first model animation; calculate the absolute value of the difference between the position data of the model bone at the second position point and the position data of the model bone at the third position point, calculate the absolute value of the difference between the rotation data of the model bone at the second position point and the rotation data of the model bone at the third position point, and obtain the target change amount of the model bone between the second position point and the third position point.

[0055] Optionally, the ratio of the target change of the model bone to the total number of target animation frames can be calculated to obtain the offset of the model bone in each target animation frame. The offset obtained in this way is the same across different target animation frames. For example, the ratio of the target displacement change of the model bone to the total number of target animation frames can be calculated to obtain the displacement offset of the model bone in each target animation frame. Similarly, the ratio of the target rotation change of the model bone to the total number of target animation frames can be calculated to obtain the rotation offset of the model bone in each target animation frame.

[0056] Optionally, calculate the change in the model's skeleton in the target animation frame and the total change in the model's skeleton in the initial model animation, and calculate the percentage corresponding to the change in the model's skeleton in the target animation frame; calculate the product of the percentage corresponding to the change in the model's skeleton in the target animation frame and the target change amount to obtain the offset of the model's skeleton in the target animation frame. The offset obtained in this way will be different in different target animation frames.

[0057] The percentages mentioned above include displacement percentage and rotation percentage. Specifically, the displacement change of the model bones in the target animation frame and the total displacement change of the model bones in the initial model animation are calculated, and the displacement percentage of the model bones in the target animation frame is calculated; the rotation change of the model bones in the target animation frame and the total rotation change of the model bones in the initial model animation are calculated, and the rotation percentage of the model bones in the target animation frame is calculated.

[0058] For example, the displacement offset of the model bone in the target animation frame is obtained by multiplying the percentage of displacement corresponding to the model bone in the target animation frame with the target displacement change amount, and the rotation offset of the model bone in the target animation frame is obtained by multiplying the percentage of rotation corresponding to the model bone in the target animation frame with the target rotation change amount.

[0059] The above method also includes: summing up the changes in the model bones in each animation frame of the initial model animation to obtain the total changes in the model bones in the initial model animation.

[0060] The total change includes the total change in displacement and the total change in rotation. Specifically, for each model bone, the displacement changes of that model bone in each animation frame of the initial model animation are summed to obtain the total displacement change of that model bone in the initial model animation. The rotation changes of that model bone in each animation frame of the initial model animation are summed to obtain the total rotation change of that model bone in the initial model animation.

[0061] One possible implementation of the above steps for increasing the offset of the target model in the target animation frame to obtain the target model animation is: increasing the offset of the model bones in the target animation frame to obtain the target model animation.

[0062] Specifically, by controlling the amount of change in the model's skeleton in the target animation frame and increasing the offset of the model's skeleton in the target animation frame, the target model animation is obtained.

[0063] Optionally, for each target animation frame in the initial model animation, the displacement change of each model bone in the target animation frame is increased by the displacement offset of the model bone, and the rotation change of each model bone in the target animation frame is increased by the rotation offset of the model bone, thus obtaining the target model animation.

[0064] For example, the displacement change of the first model bone in the first target animation frame is 1, the rotation change is 2, the displacement offset of the first model bone in the first target animation frame is 0.3, and the rotation offset is 0.1. Control the displacement change 1 of the first model bone in the first target animation frame to increase the displacement offset by 0.3, and control the rotation change 2 of each model bone in the target animation frame to increase the rotation offset by 0.1.

[0065] The aforementioned target model is pre-configured with a first controller, which is a primary controller of the target model and is used to control the first model skeleton of the target model. After the step of controlling the change amount of the target model in the target animation frame to increase the offset to obtain the target model animation, the above method further includes: in response to the stretching elimination instruction for the target model animation, determining a specified animation frame in the target model animation in which the target model has an overstretching phenomenon during movement, determining the target model skeleton involved in the overstretching phenomenon, and the target controller associated with the target model skeleton, and controlling the target controller in the specified animation frame to offset by a specified distance.

[0066] The aforementioned overstretching phenomenon refers to an excessive distance between the model's bones. Taking a character model as an example, if the distance between the waist bones and the left leg bones is too large, it will cause the left leg to be overstretched.

[0067] The target controller associated with the target model skeleton mentioned above can be a controller configured for at least part of the target model skeleton, a controller configured for model skeletons adjacent to the target model skeleton, or a controller configured for model skeletons pre-associated with the target model skeleton, wherein the pre-associated model skeletons are pre-configured by the animators. For example, the model skeleton pre-associated with the leg model skeleton is the waist model skeleton.

[0068] Optionally, for each animation frame in the target model animation, traverse each model bone in the animation frame. If the distance between the first model bone and the second model bone in the animation frame is greater than a preset threshold, determine the animation frame as a specified animation frame with overstretching.

[0069] Adding offsets to the model's skeleton can sometimes cause overstretching. For example, a running character might increase their stride length, leading to overstretching of the legs, meaning the distance between the lumbar and leg bones exceeds a preset threshold. Figure 2 As shown, the character model's left leg is noticeably elongated, which is unrealistic. At this point, the waist controller needs to be shifted downwards a specified distance to return the leg to a normal, slightly bent position. This specified distance is usually entered by the animator.

[0070] Prior to the step of adjusting the target model in the first model animation as described above, the method further includes: in response to adding instructions to the controller of the target model in the first model animation, configuring a first controller and / or a second controller for the target model; wherein the first controller is a primary controller of the target model, used to control the first model skeleton of the target model; and the second controller is a secondary controller of the target model, used to control the second model skeleton of the target model.

[0071] The first model skeleton is located at the first model position of the target model, and the second model skeleton is located at the second model position of the target model;

[0072] Taking the target model as a character model as an example, optionally, the first model position is the waist position of the target model, and the second model position is the left or right foot position of the target model.

[0073] Optionally, the first model position is the neck or head position of the target model, and the second model position is the left or right hand position of the target model. Overstretching occurs when the character model's legs or arms are too long, which is unrealistic.

[0074] Optionally, in response to a controller addition instruction for the first model bone in the target model within the first model animation, a first controller is configured for the first model bone of the target model; in response to a controller addition instruction for the second model bone in the target model within the first model animation, a second controller is configured for the second model bone of the target model; and in response to a controller addition instruction for the third model bone in the target model within the first model animation, a third controller is configured for the third model bone of the target model.

[0075] The first model skeleton is located at the waist of the target model, the second model skeleton is located at the left foot of the target model, and the third model skeleton is located at the right foot of the target model.

[0076] Corresponding to the above method embodiments, this disclosure provides a model animation processing apparatus, such as... Figure 3 As shown, the device includes:

[0077] Animation copy module 301 is used to obtain the initial model animation. Copying the initial model animation yields the first model animation. The initial model animation includes the target model, and the initial model animation is the movement animation of the target model from the first position point to the second position point.

[0078] The animation adjustment module 302 is used to respond to the adjustment operation of the target model in the first model animation, and adjust the target model's movement endpoint from the second position point to the third position point; wherein, the adjusted first model animation is the movement animation of the target model from the first position point to the third position point, and the target model exhibits a smooth movement phenomenon when its bottom is touching the ground during the movement.

[0079] The target animation frame determination module 303 is used to determine the target animation frame in the initial model animation in response to the elimination instruction for smooth movement phenomenon, wherein the target model in the target animation frame is in a non-static state.

[0080] The offset determination module 304 is used to determine the offset of the target model in the target animation frame based on the target change amount between the second position point and the third position point.

[0081] The target model animation determination module 305 is used to control the change amount of the target model in the target animation frame and increase the offset to obtain the target model animation; wherein, the target model animation is the movement animation of the target model from the first position point to the third position point, and there is no smooth movement phenomenon when the bottom of the target model is touching the ground during the movement.

[0082] This disclosure provides a processing apparatus for model animation, which acquires an initial model animation and copies the initial model animation to obtain a first model animation. The initial model animation includes a target model, and the initial model animation is a movement animation of the target model moving from a first position point to a second position point. In response to an adjustment operation on the target model in the first model animation, the movement endpoint of the target model is adjusted from the second position point to a third position point. The adjusted first model animation is a movement animation of the target model moving from the first position point to the third position point, and the target model exhibits a smooth movement phenomenon when its bottom is on the ground during the movement. In response to an instruction to eliminate the smooth movement phenomenon, a target animation frame in the initial model animation is determined, wherein the target model in the target animation frame is in a non-static state. Based on the target change amount of the target model between the second and third position points, the offset of the target model in the target animation frame is determined. The target model animation is obtained by controlling the change amount of the target model in the target animation frame to increase the offset.
