- porphyra 3y agoMore like point clouds since they are not constrained to a grid. NERF is more like voxels though.
- blovescoffee 3y agoWhat do you mean NERF is like voxels? It is very much NOT like voxels
- porphyra 3y agoThe original NERF paper had a voxel-like grid, but instead of regular voxels with a single color per grid cell, they had an MLP in each cell that models the color as a function of position and angle.
- blovescoffee 3y agoThe literal definition of a NeRF and rendering function in the original paper are a continuous non-discretized vector-field and sampling based render function.
- porphyra 3y agoI'm sorry, you're right. I got confused with some other papers like Plenoxels that use voxels.
