View projection

• each pixel of the projector maps to a number of pixels in the camera, captures light transport from projector to displayed image
• this gives a view projection matrix (VPM), that simulates the projector and its environment
• the pseudo inverse of the matrix can be used to determine the projection that will generate the desired result
• simplify view project matrix using the assumption that separate pixels do not overlap in the result, hence can keep just the max value in each row of the VPM
• pseudo inverse of simplified matrix can be computed easily
