Model Differential Property #25

Open lifunudt opened 2 years ago

lifunudt commented 2 years ago

Hi, thx for sharing the great works. I am curious about the differential property regarding the input rays. When backward model, can the gradient be passed to the input sampled points?

maybe the appendix part (B.3. Analytic Derivatives of PlenOctree Rendering) of PlenOctrees (https://arxiv.org/abs/2103.14024) could be helpful to you
