- deipoda 8y agoHi colah3, I was wondering how you're able to propagate the gradient through the renderer. What I mean is: f(X,Y,Z) = (x,y) (Mapping from 3D to 2D using renderer) g(x,y) = (u,v) (mapping xy and uv) h(x,y) = (r,g,b) (actual rendered image) p(u,v) = (r,g,b) (texture map image) gradient from upper layer is going to be wrt h(x,y) - dL/dh(x,y). How do you propagate this to get dL/dp ? (Please let me know if this is explained in detail somewhere. Thanks!)
