Closed BaiBF closed 9 months ago

Thank you for sharing such a great code! but i have a question, the fn "intersect_sphere" (in ddp_train_nerf.py) 's return d1+d2, In my understanding， is the ratio of vector ray_d. why fg_far_depth(d1+d1) does not multiply by ray_d . like fn"depth2pts_outside"in(ddp_model) line 27. hope you can answer the reason, thanks

Subsequent operations multiplied by ray_ D
