I have a rotation matrices, and I have to do a few things with it. If the matrix represents the rotations around three axis, 1) how do you apply the rotation around 1 axis to another matrix ? for example : I want the other matrix to have only the y-rotation of the other axis. For example, when I want a 3rd person camera. 2) how do you set the rotation around a specific axis to a value. But without touching the rotations around the other axis ? For example, when I want a camera to look at a specific height. 3) how can you get the inverse rotation ? Thanks in advance. [Edited by - hannibar on March 21, 2005 4:36:12 PM]

There's one handy FAQ which deals with all things matrix related; I've lost the link, maybe someone else knows the name of the site..

I did a search on google. It probably is :
http://skal.planet-d.net/demo/matrixfaq.htm
Although it is a VERY interesting link (I'll read it a little better when I have more time), it doesn't answer my question 1) and 2).

So if anyone knows an answer to these, feel free to post it.

Thanks
