Hi I am having a slight problem and cant seem to find the remedy for it just yet...
What I am doing is creating an optical illusion system for an artist. The idea is that when the person is moving then they will appear in the pattern as a silhouette, but will have a pattern on them, and when their movement is minimal then they will disappear into the canvas again. It is a simple idea but there is one thing catching me out.
I am trying to map a pattern to just the colour black but alas am having no good results. Has anyone got an idea of how to just overlay on a single colour?
e.g. use [pix_movement] to convert frame-differences into RGBA (obviously in RGBA colorspace) and [pix_takealpha] to use this alpha-mask for your pattern-image to do the blending.
