regular photogrammetry usually means searching for common features in a bunch of photos.
if you find the same feature in 3 photos you can triangulate its location in 3d space.
the output of this process is a point cloud which you can then process into a triangle mesh.
(google structure from motion).
this OTH is differentiable voxel rendering. so basically optimizing the colors of a bunch of cubes to make it look the pictures.
using backpropagation just like you would do it for neural networks.
