If the following approach can be realized, voxel models could to a greater extent replace traditional models, often freeing creators from the need to perform topology work or unwrap UVs.
Currently, most 3D animations in the market heavily rely on traditional skeletal systems and quad face models. My conception, however, is an entirely new approach to joint solutions based on voxel models. At the heart of this system lies the introduction of "invisible universal joints," which act as pivotal components connecting limbs, enabling unprecedented degrees of freedom and flexibility. Specifically, each joint not only supports unidirectional and planar rotations but also allows for adjusting the distance at connection points within a certain range, thereby more accurately simulating the functionality of complex human structures like the shoulder joint.
### Design Considerations
- **Universal Joints**: Develop a series of customizable-position universal joints for precise control over every action of the model, enhancing the naturalness of animations.
- **Distance Adjustment**: Incorporate a mechanism for adjusting distances at joints to mimic limb extension and retraction, augmenting the realism of animations.
- **Interconnected Functions**: Drawing from the principles of parenting and IK (Inverse Kinematics) in skeletal systems, enable natural chain reactions between joint movements, boosting animation efficiency and fluidity.
### AI-Assisted Animation Optimization
To refine this system further, I propose integrating AI technology, specifically aimed at correcting any uneven seams or visual inaccuracies that may arise from joint manipulations. By training specialized AI models, we can instantly conduct seamless repairs after users adjust the model's actions, preserving the continuity and realism of the model's surface. Considering your company's leadership in technological innovation, I am confident that realizing this AI-assisted feature is well within reach.
### Accompanying Illustrations
To visually illustrate my concept, I have attached three key example images:
1. **Original Voxel Model**: Showcases a meticulously crafted voxel male model, serving as the base model.
2. **Sphere-Jointed Puppet in Pose**: This image depicts the model transformed into a sphere-jointed puppet, with joints set and posed in a specific action, offering a preliminary glimpse into its dynamic potential.
3. **Model After AI Refinement**: The final image exhibits the model after AI processing, where flaws at joints are impeccably corrected, resulting in a smooth surface and natural movement.
### Conclusion
Long live voxel models!
