They improved SDS, an existing method for text-to-3D.
The main idea of the paper is called TP-SDS, which used unique timestep sampling method different with original SDS.
They figured out non-increasing timestep sampling is more appropriate on NeRF optimization process and design new weight function w*(t) for time step sampling.
