I am attempting to build a "physical" mirror in maya similar to the artworks of Danny Rozin
I have a black and white animation applied to a plane and would like to find a way to sample the grayscale values (0-255) from the pixels and use that data to drive the position of their corresponding units. I am having trouble finding a method that will give me the grayscale values as a usable output. I have messed around with the sampler info node, but it seems to only sample the scene upon rendering and only samples information based on location and orientation. Any suggestions would be appreciated. BTW, I'm doing this for a class so giving up is not an option ;)
Used the video as a displacement map-> created curves from surface edges on the animated surface-> point constrained attractor assets to points along the curves, creating an attractor matrix-> used the distance data generated from the moving attractors to drive the rotations of the corresponding units.
