[0034] Step S204 , based on the preset role action requirements corresponding to the virtual character, the joint parameters in the initial skeleton model are adjusted to obtain a target skeleton model.

[0035] Step S206: Control the movement of the virtual character based on the skeleton model to generate animation of the virtual character.

[0036] The metaverse is a comprehensive concept, referring to a collective virtual shared space that merges virtual augmented physical reality with physically persistent virtual space. It encompasses the sum of all virtual worlds, augmented reality, and the internet. The metaverse system can be understood as the collection of technologies, platforms, and network ecosystems that support and realize the concept of the metaverse. Within the metaverse system, avatars are users' avatars in the virtual world, representing their identity and personality. Avatars can have complex forms and functions and are a key component of the metaverse experience.

[0037] First, you can create an initial skeletal model for the avatar. A skeletal model is a modeling and animation technique used in 3D animation, primarily for controlling and expressing the movements of complex 3D models (such as characters and animals). The core concept of a skeletal model is to simplify the internal structure of a 3D model into a set of connected bones. This skeleton mimics the skeletal structure of real-world creatures, enabling natural and smooth animation. The skeletal structure can be designed based on the desired avatar shape and expected range of motion. Bones typically consist of a series of joints, each connecting different body parts, such as the head, torso, and limbs. N represents the number of joints in the skeletal model, which depends on the complexity of the avatar and the required motion. For example, a highly realistic avatar may have over 100 joints to achieve detailed movements. Properties are set for each joint, including rotation axis, range of motion, stiffness, and elasticity, to ensure that the model exhibits natural and plausible motion during animation. Based on the avatar's role setting and motion requirements in the metaverse, such as walking, running, jumping, fighting, or dancing, you can analyze which joint parameters need adjustment. The parameters of the joints are then adjusted to meet the motion requirements. This may include increasing the flexibility of the joints, adjusting the limits of rotation and translation, setting physical constraints, etc., to ensure that the virtual character can perform the required actions while remaining natural and stable, and obtain the target skeletal model. Finally, the skeletal animation tools in animation software or game engines can be used to control the movements of the virtual character by manipulating the rotation and translation of the bones. Keyframe animation can be set to define the position and rotation of the joints at specific points in time, and the software will then automatically calculate the transitions between keyframes to generate a continuous animation.

[0038] It can also be combined with some physics engines to add physical simulation to the skeletal model, such as gravity, collision and friction, to ensure that the movement of the virtual character conforms to the rules of physics and increase the realism of the animation.

[0039] By following these steps, it is possible to create and control virtual characters with complex joint systems in the Metaverse system, enabling them to perform various actions and generate high-quality animations. This not only enhances the realism and immersion of the user experience in the Metaverse, but also greatly enriches the expressiveness and interactivity of the characters in the Metaverse.

[0040] Optionally, in the animation generation method provided in an embodiment of the present application, an initial skeletal model corresponding to the virtual character in the metaverse system is established, including: obtaining a skin mesh corresponding to the 3D model of the virtual character; creating a skeletal system, wherein the skeletal system includes a trunk, limbs, and joints; binding the gateway vertices of the skin mesh corresponding to the 3D model to the skeletal system to obtain an initial skeletal model.

[0041] First, create or obtain a 3D model of an avatar, typically using 3D modeling software. This model consists of a mesh, composed of vertices, edges, and faces, that represents the avatar's appearance. Once the model is ready, you can use the software's features to export a skinned mesh. The skinned mesh must retain the positional information of all vertices for subsequent rigging. The skeletal structure can be planned based on the avatar's morphology and movement requirements. The skeletal system typically includes the trunk, limbs, and head, as well as the joints between these parts. The trunk is often composed of multiple segments, such as the spine, to support complex bending and twisting. Create a skeletal model in the 3D modeling software, including all planned bones and joints. The skeletal model should reflect the skeletal movement of real creatures. Use the software's skinning and rigging tools to bind the 3D model's skinned mesh to the skeletal system. This rigging process ensures that the model deforms as the skeleton rotates and moves, maintaining a natural and smooth animation.

[0042] For example, creating a skeletal system typically begins with the main spine and then expands to the limbs and head. Rotation and rotation limits can then be added to each joint to ensure natural and controllable skeletal movement. A skinned mesh is then created to bind the character model's geometry to the skeletal system, allowing the model to deform according to the skeleton's movement.

[0043] After rigging is complete, preliminary animation tests can be performed to check whether the skinned mesh deforms naturally and the joints move smoothly when the avatar performs basic movements (such as walking and running). Based on the test results, it may be necessary to adjust the position and length of the bones or redistribute the weights to optimize the animation performance. This process may require multiple iterations until a satisfactory animation effect is achieved.

[0044] Through these steps, the 3D model of the avatar is bound to the skeletal system, forming an initial skeletal model. This model is the foundation for all subsequent animation production, enabling the avatar to perform various complex movements and create dynamic and interactive scenes.

[0045] Optionally, in the animation generation method provided in an embodiment of the present application, based on the preset role action requirements corresponding to the virtual character, the joint parameters in the initial skeleton model are adjusted to obtain a target skeleton model, including: based on the role action requirements, obtaining the rotation range corresponding to each of the N joints corresponding to the virtual character; based on the rotation range corresponding to each of the N joints, determining the rotation parameters corresponding to the N joint models; based on the rotation parameters corresponding to the N joint models, adjusting the joint parameters in the initial skeleton model to obtain the target skeleton model.

[0046] In one or more optional embodiments, N joints requiring attention can be determined based on the character's settings and preset range of motion. These typically include joints in the spine, limbs, fingers, head, and face, with the specific number N depending on the model's complexity and the required motion. The specific motions the character is required to perform, such as walking, running, jumping, fighting, and facial expressions, can be analyzed to determine the motion patterns of each joint during these movements. Based on these motion patterns, the natural rotation range of the joints of the human body or a specific creature in real life can be determined. For example, the shoulder joint can rotate omnidirectionally, while the knee joint rotates primarily along a single axis. Considering the character's motion requirements, the natural rotation range may need to be expanded or restricted. For example, to achieve certain exaggerated or acrobatic movements, a larger joint rotation range may be required; to maintain the realism of the animation, the rotation range of certain joints may need to be restricted. Rotation parameters can be set for each joint model, including the rotation axis, minimum and maximum rotation ranges, and rotation speed. These parameters should be determined based on the analysis in the previous step to ensure they support the desired animation effects. For some joints, you may need to set physical constraints, such as joint rigidity or elasticity, to simulate real-world physical effects, such as muscle stretching and joint stress limits. In 3D modeling software, you can edit the skeleton model and adjust each joint according to the determined rotation parameters, including adjusting the position and length of the joint, as well as modifying the rotation and movement limits of the joint. After adjusting the skeleton parameters, you may need to readjust the weight distribution of the skin mesh to ensure that the model deforms and moves more naturally when performing animation.

[0047] The rotation range and parameters of the joints are directly related to the naturalness and realism of the virtual character animation. By adjusting them, we can ensure that the virtual character can show dynamic effects that are consistent with anatomical principles and meet the needs of artistic creation when performing various actions.

[0048] Optionally, in the animation generation method provided in an embodiment of the present application, based on the role action requirements corresponding to the preset virtual character, the joint parameters in the initial skeleton model are adjusted to obtain a target skeleton model, including: determining the muscle control weight corresponding to the virtual character based on the role action requirements, wherein the muscle control weight represents the degree to which the muscle is affected by the corresponding joint movement; based on the muscle control weight, assigning corresponding weight values ​​to N joint models; based on the weight values ​​corresponding to the N joint models, adjusting the joint parameters in the initial skeleton model to obtain a target skeleton model.

[0049] In one or more optional embodiments, the muscle control weights corresponding to the virtual character can be determined based on the character's action requirements, and the joint parameters in the skeletal model can be adjusted accordingly. Because the muscles of the human body and other organisms are not evenly distributed, the intensity and range of influence of different actions on the muscles are also different. By adjusting the muscle control weights, the degree of participation of specific muscle groups in different actions can be simulated more accurately, so that the animation effect looks closer to the behavior of real organisms. In addition, improper distribution of muscle control weights will cause unnatural deformation of vertices in the animation. For example, when the character is running, the leg mesh may be uncoordinated and distorted. Adjusting the muscle control weights and ensuring that the vertices are deformed according to the correct muscle movement logic can eliminate these unnatural phenomena and make the character's movement more smooth and realistic.

[0050] First, analyze the types of movements your avatar needs to perform, understanding how muscles contract and extend during these movements and which muscle groups are most critical. Then, assign weights to each component of the muscle model, reflecting the degree of influence the muscle has on the skeletal movement. For example, when raising an arm, the biceps brachii would have a higher weight because it's primarily responsible for this movement. Determine the extent to which each joint's movement affects surrounding muscles. Muscle control weights aren't limited to muscles directly associated with the joint; they also take into account indirectly affected muscle groups, such as spinal rotation, which may affect back and abdominal muscles. Based on the muscle control weights, calculate the influence each joint has on nearby muscles. This step may require the use of software algorithms or manual adjustments. For each mesh vertex, ensure that the sum of the weights of all joints influencing it equals 1 to ensure consistent and natural deformation of the model. Based on the muscle control weights and assigned joint weights, optimize the joint parameters in the skeletal model, such as the joint's rotation axis, rotation angle limits, and range of motion, to match the natural response of the muscles. By adjusting the stiffness and elasticity of the joints, you can simulate muscle tension and relaxation, making the movements more realistic. For example, the knee joint needs more flexibility when jumping and more rigidity when standing.

[0051] After these adjustments and optimizations, the resulting target skeletal model should be able to achieve more refined and realistic animation, making the avatar's movements appear as if driven by real muscles. Dynamic skeletal effects allow character models greater flexibility in movement and expression, and developers can adjust the position and rotation of bones as needed to achieve more natural and smooth animation. Based on the character's movement requirements, the skeletal model of the avatar is built and optimized to achieve greater realism, thereby enhancing the user's immersion and experience in the Metaverse.

[0052] Optionally, in the animation generation method provided in the embodiment of the present application, the movement of the virtual character is controlled based on the skeleton model to generate the animation of the virtual character, including: receiving motion instructions based on the target account input; based on the motion instructions, controlling the movement of the virtual character according to the skeleton model to generate the animation.

[0053] The Metaverse system receives motion commands based on target account input and controls the movement of virtual characters based on a skeletal model to generate animations. Users can send motion commands to the Metaverse system using input devices such as game controllers, keyboards, mice, or even virtual reality (VR) headsets and motion capture devices. These commands can be the pressing of arrow keys, the tilting of joysticks, the swiping of touchscreens, or other forms of user input. The system parses and understands these user inputs, translating them into commands for the virtual character's movements. For example, pressing a joystick forward might be interpreted as a "walk forward" command. Motion commands are associated with target accounts, ensuring that the movement of each virtual character is controlled by its corresponding user. The system identifies the user account and directs received motion commands to the virtual character associated with that account. The system utilizes a skeletal model to control the movement of the virtual character. The joints in the skeletal model rotate and translate according to the received motion commands, causing the skin mesh to deform, thereby achieving animation effects and generating animations.

[0054] Through this process, the metaverse system can respond to user input in real time, use skeletal models to control the movement of virtual characters, and generate high-quality animations, allowing users to interact with the virtual world and experience immersive gaming or social experiences.

[0055] Optionally, in the animation generation method provided in the embodiment of the present application, based on motion instructions and according to the skeleton model, the movement of the virtual character is controlled to generate animation, including: detecting whether the virtual character collides during the movement; in the event of a collision of the virtual character, generating joint movement instructions, wherein the joint movement instructions are used to control the joint movement of the virtual character to simulate the collision effect; based on the joint movement instructions, according to the skeleton model, the joint movement of the virtual character is controlled to generate animation.

[0056] In one or more optional embodiments, collisions are detected during the movement of the avatar, and appropriate joint movement instructions are generated in the event of a collision to simulate collision effects and generate corresponding animations, making the collision effects more realistic. Collisions between the avatar and dynamic obstacles (such as other moving characters) and static environmental objects (such as walls and the ground) can be continuously detected. To improve the accuracy of collision detection, both the avatar and environmental objects require accurate collision body representations. The collision body can be a simple geometric shape (such as a sphere, cube, or capsule) or a complex convex hull or mesh representation. Once a collision is detected, the direction, force, and location of the collision can be analyzed to determine how the avatar should respond. Based on the collision analysis, specific joint movement instructions can be generated. This may mean adjusting the angle of a leg joint to simulate a stumble or moving an arm joint to simulate an occlusion. Joint movement instructions should mimic the reactions of real creatures as closely as possible to enhance the realism of the animation. When generating instructions, the physical constraints of the joints, such as rotation range and speed limits, need to be taken into account to avoid movements that exceed the reasonable biological range and maintain a natural and safe animation. After receiving the joint movement instructions, the relevant joints in the skeletal model move according to these instructions. This may involve the coordinated movement of multiple joints to achieve a complete collision response animation.

[0057] In some cases, to better simulate collision effects, weight distribution may need to be dynamically adjusted to ensure that the deformation of the model surface matches the joint movement and maintain the integrity of the animation. After receiving the joint movement instructions, the game engine or metaverse platform updates the skin mesh in real time, controls the joint movement of the virtual character, and ultimately renders the collision response animation.

[0058] Through the above process, it can be ensured that when the virtual character moves in the metaverse system, it can correctly respond to various collision events and show natural movements that conform to the laws of physics, thereby enhancing the realism and immersion of the user experience.

[0059] The animation generation method provided in the embodiment of the present application establishes an initial skeleton model corresponding to a virtual character in a metaverse system, wherein the initial skeleton model includes N joint models, where N is a positive integer; based on the preset role action requirements corresponding to the virtual character, the joint parameters in the initial skeleton model are adjusted to obtain a target skeleton model; based on the skeleton model, the movement of the virtual character is controlled to generate an animation of the virtual character, thereby achieving the purpose of generating animation based on the skeleton model, thereby realizing the technical effect of improving the smoothness of the animation and reducing the jamming, and further solving the technical problem in the related art of using a physical engine to process virtual characters in the metaverse system, resulting in high resource consumption and easy jamming.
