Directed Distance Fields for Constant-Time Ray Queries on Gaussian Splatting 事件

Directed Distance Fields for Constant-Time Ray Queries on Gaussian Splatting arXiv:2606.00817v1 Announce Type: cross Abstract: 3D Gaussian Splatting (3DGS) renders new views of a scene in real time. Like every rasterizer, it answers only primary rays, the rays from the camera through the image. It cannot trace the secondary rays that shadows, ambient occlusion, and global illumination need. We turn a trained 3DGS scene into a ray oracle by distilling a Directed Distance Function (DDF). The DDF
