hi pd people!
i'm working on this project:
the basic idea is to create an interactive installation, where anyone could move around with a bluescreen behind his back, while in front of him, there would be a projection screen with a huge crowd of clones of oneself facing the performer..
i need to capture a person in front of a bluescreen, create alpha channel of the person, multiply it and import it into a picture (for example a picture of some plaza) so that it would look like a regiment of clones moving around in a grid.. in perspective..
i think i'd need functions pix_alpha / pix_chroma_key / pix_mask for the alpha channel processing.. and then some other GEM functions to multiply it and create a grid inside a picture.. but i'm not sure exactly how..
all i ask is to kick me in the right direction..
