PointGT: Simultaneous Geometry and Texture Editing for Point-Based Representations

Researchers introduced PointGT, a point-based 3D representation enabling simultaneous geometry and texture editing, addressing limitations of existing volumetric methods like 3D Gaussian Splatting that struggle with geometry edits. The method combines a point-based representation with a learned UV mapping technique to support high-resolution texture editing and fine-grained deformations while maintaining high rendering quality.

arXiv:2609.03341v1 Announce Type: new Abstract: We present PointGT, a point-based 3D representation that enables simultaneous editing of object geometry and appearance. Existing reconstruction and view synthesis techniques produce volumetric 3D representations that are high-quality and photorealistic, but are difficult to edit. In particular, recent efforts to enable texture editing for 3D Gaussian Splatting representations are not compatible with geometry edits and deformations. Our method combines a point-based representation that is well-suited for geometry deformations with a learned UV mapping technique that enables high-resolution texture editing. We show that PointGT enables fine-grained editing of both geometry and texture in point-based neural representations with high rendering quality.
