Radiant Foam: Real-Time Differentiable Ray Tracing
TL;DR: โIn a nutshell, our solution, which we name Radiant Foam (Fig. 2), provides 3DGS-like rendering speed and quality, but has a training modality based on rays that resembles the one from NeRF [28]. This implies that many NeRF techniques can now be seamlessly adapted to our method ๐ฑ, with the significant advantage that the underlying geometry is explicitly represented by a volumetric mesh.
We parameterize this volumetric mesh as a 3D Voronoi diagram (Fig. 1), which enables the training of a mesh structure with dynamic connectivity through gradient descent by avoiding the discontinuities associated with discrete changes in other representations. We also propose a coarse-to-fine training approach, which enables the rapid construction of mesh models with adaptive resolution.โ
