Hey everyone! I'm trying to find a way to project colored "shadows" onto my scene using a pixel shader (HLSL). That color information should be provided by a given texture (actually a photo). Unfortunately I'm not too sure about what approach I should choose to do this. I've read a bit about light transmission and using it with images, but I don't really get the grip of how exactly that'd work. My first assumption was to cast the "colored shadows" like usual shadows (what technique would be suited best for that purpose?) and then sample the color information from the texture. My big question here would be how exactly to sample the color information. Any info on that subject would be very appreciated :D Greets, Philipp
