SUMMARY:DeMapGS: Simultaneous Mesh Deformation and Surface Attribute Mappi
 ng via Gaussian Splatting
DESCRIPTION:Shuyi Zhou (The University of Tokyo); Shengze Zhong, Kenshi Ta
 kayama, and Takafumi Taketomi (CyberAgent); and Takeshi Oishi (The Univers
 ity of Tokyo)\n\nWe propose DeMapGS, a structured Gaussian Splatting frame
 work that jointly optimizes deformable surfaces and surface-attached 2D Ga
 ussian splats. By anchoring splats to a deformable template mesh, our meth
 od overcomes topological inconsistencies and enhances editing flexibility,
  addressing limitations of prior Gaussian Splatting methods that treat poi
 nts independently. The unified representation in our method supports extra
 ction of high-fidelity diffuse, normal, and displacement maps, enabling th
 e reconstructed mesh to inherit the photorealistic rendering quality of Ga
 ussian Splatting. To support robust optimization, we introduce a gradient 
 diffusion strategy that propagates supervision across the surface, along w
 ith an alternating 2D/3D rendering scheme to handle concave regions. Exper
 iments demonstrate that DeMapGS achieves state-of-the-art mesh reconstruct
 ion quality and enables downstream applications for Gaussian splats such a
 s editing and cross-object manipulation through a shared parametric surfac
 e.\n\nRegistration Category: Full Access, Full Access Supporter\n\nSession
