hi again... following question: I use the bone animating system for my animations. Now if i draw the model an transform from a parent to child..is there a way to get to the parent again, without having to LoadIdenty(); ? Or, in a otherway asked... how do i turn a matrix around, to get me to the place i came from? I know, maybe a bit hard to understand ''cause i''m not that good at explaining...ok? thx, Phil

You should use the matrix stack:
glPushMatrix, glPopMatrix

if your using D3D you can use D3DMatrixStack or something like that I belive, or just make your own with a class or a struct

Here is a very bad suggestion (OOPS!)
Calculate Matrix Inverse and reapply it.

There is no problem so complicated that it cannot be complicated further.
