Rotation with matrix


I have a cube with a bone, and I apply rotation on the bone.
And I want rotate another cube like the first with the matrix rotation of the bone.

My goal is to export the animation on OpenGL. But I don’t know which matrix use…
I have read lot of manipulation but no done.

Thanks for help.

I’m french and I hope my english is not too bad :smiley:

Hi, these kinds of issues depend quite a lot on what the external application expects - suggest to break this down into smaller problems and solve each 1 by 1.

Exporting bones can be a hassle since every application seems to treat them a little different, though if you only need the resulting, final transformation - its not that hard.
