Hello,
my name is Fabian and i'm writing my master thesis of computer science at the University of South Australia.
Im working at a project concerning the llumination of real 3D models with multiple projectors.

I need some general help and information about IR and i hope, you will help me..

My goal is to detect the shadows on the model cast by users stepping in front of the projector. Three different approaches dealing with IR might be possible..

1) Illuminating the whole scene with IR-light and detecting the IR shadow of the user on the model.

2) Is it possible to detect the user via thermography in a multi-projector illuminated environment?

3) or do you have knowledge of any white paint color with special reflective attributes?
e.g. reflecting visible light in a normal way, but absorbing all IR waves? (that would be the easiest solution for me)
or a material that reflects visible and IR waves in a different way?

I ll appreciate any useful comments on this topic.
regard
Fabian
