Hello! That's very interesting but definitely not supported, so you would need to make your own modifications.
First of all, you should pass the image to both forward and backward passes and then change the renderCuda
functions in both forward.cu
and backward.cu
to account for the background colour.
Naturally, you should have a mapping between the rays and the image.
Having that, you can then replace the background colour with the value you get by querying your image with your mapping. So basically, whenever you see bg_color
you should put the queried value.
If I were you, though, I would double-check the various equations that take place, to make sure everything is correct, as the original code uses black colour as background and masking any potential errors.
