I think this little question have more solutions, but in this time I'm don't know anyone ((
How to change center of rotating point if I need it not in center of gridshape, but in one of it's corner ???
And another important thing - I have many gridshapes and all of it need to rotate in same direction and have same point of rotating!! So solution with rotation all of rendered world is no good way (
In the end of work it's must be a model of human moving using Wiimote and camera. That you're can suppose - I need joint(articulation) to model body!
Thanks for your time!!
