Nov 12, 2024, 2 min read

TensoRF is a 🌞 NeRF that models radiance fields with voxel feature grids and . From them, our radiance field is

where and represent trilinear interpolation of continuous from the voxel grid and is an appearance processing function.

Instead of directly optimizing and , we decompose it into a sum of outer products and optimize and instead:
