where can I find these files?

Hello, I am looking to include these files:

#include "Camera/abstract_camera.h"
#include "Camera/linear_camera.h"
#include "maths_utils.h"
#include "sim3.h"

any idea on where I can find them? I googled and could not find them

Gee, that's funny, cause I found all of them simply by Googling that first include line.

Where at, though? Comments like that don't help much...

By Googling the first include line. There are only five hits; one of them is this page, the other four are all the same place (ETA, because there's no reason to be coy: an SVN repository at the University of Freiburg), which conveniently is the place you are looking for.

okay, thanks!!!
