To be honest, since it is filmed from the exact point as where the beamer is, I doubt it is 3 projectors, but just 1, and than they just masked out the roof. That is why I hate these “on a tripod” recordings for object mapping.
Anyway, if you are sure it is 3D, and if you know your 3D software, try to model the room where you project in/on and read here: how to project on 3d geometry
also check out GridEditor and PointEditor. you can distort a texture via dragging and dropping points. its a fast way of doing projection mapping without calculating anything. just do it for all three projectors separately.
I made slight progress on this project, and I tried to read the suggested tutorials.
I’m trying to do the projection on 3 surfaces using 1 projector. I’m having problems on how to project on the 3 surfaces. I’m using grideditor to project a 3d model on a wall corner.
currently I can’t make the projection to look right from the viewer point.
I’m sure there is a simple solution, but I need it ready in a matter of days for the arch. degree final project.
As I’m new to VVVV, I’ll appreciate if someone would agree to send me his/her mail/skype (also a time when it’s OK to call of course) so I can call and ask a few questions for a simple resolution of the probelm… :-)
