Enhancing non-Rigid 3D Model Deformations Using Mesh-based Gaussian Splatting
This work enhances 3D content-creation workflows for applications in virtual reality, character animation, and interactive design, though it appears incremental as it builds on existing mesh and Gaussian splatting techniques.
The paper tackles the problem of limited post-editing capabilities and support for large-scale non-rigid deformations in traditional 3D Gaussian splatting by embedding Gaussian kernels onto explicit mesh surfaces, enabling intuitive editing operations like moving, scaling, and rotating components for complex deformations such as bending and stretching.
We propose a novel framework that enhances non-rigid 3D model deformations by bridging mesh representations with 3D Gaussian splatting. While traditional Gaussian splatting delivers fast, real-time radiance-field rendering, its post-editing capabilities and support for large-scale, non-rigid deformations remain limited. Our method addresses these challenges by embedding Gaussian kernels directly onto explicit mesh surfaces. This allows the mesh's inherent topological and geometric priors to guide intuitive editing operations -- such as moving, scaling, and rotating individual 3D components -- and enables complex deformations like bending and stretching. This work paves the way for more flexible 3D content-creation workflows in applications spanning virtual reality, character animation, and interactive design.
