What tools / software / techniques are people using these days for advanced blending between multiple projectors?
The sort of thing I mean is mapping a detailed irregular surface using multiple projectors to hit objects from different angles. In this situation you end up with a complex blend with the potential for many little 'islands' (separated active areas in each projector), and the need for these to have a soft edge.
Is there an external tool I could use to generate the blend masks, or is there an up to date vvvv technique?
I can conceive of building a vvvv system that would check check each mesh vertex / pixel was only projected on by one projector but I might wouldn't know how to create a soft edge between the different areas. Is there a standard way of calculating this?
To be clear - what I'd want to generate, either in vvvv or another tool, is one texture to apply to a single mesh for each projector, to act as a blend mask so that projector only outputs what it's meant to.
