Hi @ashawkey , thanks for your fantastic work! I played with the sdf training, but I found it was very slow compared to the original instant ngp. It is said in the paper that it takes about 15s to generate a reasonable result. However, it takes about 50s for each epoch in torch ngp. May I ask why there is such a difference? Thanks.
