WebMar 11, 2024 · The camera position in the normalized prism is just (0,0). It just has the quirk that your rays are all parallel rather than converging to the same point. So in camera space, the ray for a given pixel (x,y) is just (x,y,-1) (or +1) if you want that ray in world coordinates, then just multiply it by the inverse of your vertex transformation matrix.
