PointGT: Simultaneous Geometric and Textural Editing for Point-Based Representations

We present PointGT, a point-based 3D representation thatenables simultaneous editing of object geometry and appearance. Ex-isting reconstruction and view synthesis techniques produce volumetric3D representations that are high-quality and photorealistic, but are dif-ficult to edit. In particular, recent efforts to enable texture editing for3D Gaussian Splatting representations are not compatible with geometryedits and deformations. Our method combines a point-based represen-tation that is well-suited for geometry deformations with a learned UVmapping technique that enables high-resolution texture editing. We showthat PointGT enables fine-grained editing of both geometry and texturein point-based neural representations with high rendering quality.
