Plenoxels: Radiance Fields without Neural NetworksPlenoxels Radiance Fields without Neural Networks CVPR 2022 (Oral) We propose a view-dependent sparse voxel model, Plenoxel (plenoptic volume element), that can optimize to the same fidelity as Neural Radiance Fields (NeRFs) without any neural networks. Our typical optimization time is 11 minutes on a single GPU, a speedup of two orders of magnitude compared to NeRF. Given a set of calibrated imag
