PointGT introduces a novel point-based 3D representation that facilitates simultaneous editing of both object geometry and texture, addressing the limitations of existing volumetric techniques. By integrating a robust point representation for geometry deformations with a learned UV mapping approach for high-resolution texture editing, the method achieves fine-grained control over 3D models. Experimental results demonstrate that PointGT maintains high rendering quality while allowing for complex edits, significantly enhancing usability in 3D content creation.
PointGT allows for seamless editing of 3D geometry and texture, overcoming the limitations of traditional volumetric methods.
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.
