- Introduces radiance meshes, a technique for representing radiance fields using Delaunay tetrahedralization.
- Achieves faster rendering speeds than prior radiance field representations through a new rasterization method.
- Uses a Zip-NeRF-style backbone to handle topological discontinuities during optimization.
- Enables high-quality, real-time view synthesis on standard consumer hardware.
- Supports applications like fisheye lens distortion, physics-based simulation, and mesh extraction.
- Optimizes Delaunay triangulation by querying a neural field at tetrahedron circumcenters for smooth transitions.
- Stores field attributes in an instant-NGP, optimizing scene parameters including 3D points and neural network weights.
- Surpasses Radiant Foam in quality due to stabilized optimization and flexible triangle composition.
- Sorts tetrahedra using the power of the circumsphere for efficient rendering, leveraging a single radix sort.
- Demonstrates compatibility with graphics ecosystem, including simulation and surface mesh extraction.
- Achieves state-of-the-art performance per primitive across MipNeRF 360 scenes.
