Hi everyone,

I´ve been carefully reading your discussion which is really interesting for me.
I have an important question related to projecting on 3d geometry and i suppose that will be interesting for someone else.

In most cases (like Nathan´s example), projector perspective and spectator´s viewpoint are the same, or are supposed to be equal. Then workflow is conceptually easy:

1. map reality
2. apply lens correction
3. make a 3d model
4. process it
5. render it (projector position) with lens correction
6. project it

Ok, but what happens when projector´s position and spectator´s viewpoint are not the same?
For example sometimes you have to work with several projectors that project on the same object. This problem can be solved by placing the projectors close together, then each perspective will be nearly the same.
Ok, but if projectors are placed in order to cover for example an sphere we are going to have 3 different perspectives: each projector perspective (that will be completely different) and spectator´s viewpoint…

This problem is solved here

by using vvvv , a real time 3d software… but, how can be this done in C4D?

Thanks a lot! this question is really making me crazy

Bye!!
