Enhancing non-Rigid 3D Model Deformations Using Mesh-based Gaussian Splatting (2507.07000v1)

Abstract: 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.
