Instant neural graphics primitives with a multiresolution hash encoding
TL;DR: A versatile new input encoding that permits the use of a smaller network without sacrificing quality, thus significantly reducing the number of floating point and memory access operations is introduced, enabling training of high-quality neural graphics primitives in a matter of seconds, and rendering in tens of milliseconds at a resolution of 1920×1080.
Proceedings ArticleDOI
Variable Bitrate Neural Fields
Towaki Takikawa,Alex Evans,Jonathan Tremblay,Thomas Müller,Morgan McGuire,Alec Jacobson,Sanja Fidler +6 more
TL;DR: A dictionary method for compressing feature grids, reducing their memory consumption by up to 100 × and permitting a multiresolution representation which can be useful for out-of-core streaming is presented.
Proceedings ArticleDOI
Fast approximations for global illumination on dynamic scenes
TL;DR: An innovative lighting algorithm is presented that allows scenes to be displayed with approximate global illumination including ambient occlusion and sky-light effects at real-time rates and displays a striking aesthetic style by reducing traditional constraints of physical correctness and a standard lighting model.
Journal ArticleDOI
RTMV: A Ray-Traced Multi-View Synthetic Dataset for Novel View Synthesis
Jonathan Tremblay,Moustafa Meshry,Alex Evans,Jan Kautz,Alexander Keller,Sameh Khamis,Charles Loop,Nate Morrical,Koki Nagano,Towaki Takikawa,Stan Birchfield +10 more
TL;DR: Sparse Voxel Light Field (SVLF), an efficient voxel-based light-based approach for novel view synthesis that achieves comparable performance to NeRF on synthetic data, while being an order of magnitude faster to train and two orders of magnitude quicker to render.
Proceedings ArticleDOI
Instant Neural Radiance Fields
Thomas Müller,Alex Evans,Christoph Schied,Marco Foco,András Bódis-Szomorú,Isaac Deutsch,Michael Shelley,Alexander Keller +7 more
TL;DR: This work extends the instant NeRF implementation to allow training from an incremental stream of images and camera poses, provided by a realtime Simultaneous Localization And Mapping (SLAM) system, to improve reconstruction quality.
