Currently I need the concret values for the translate ans rotate.

The actual situation is, that I've two macros

AnimTranslate(arVertics, vTrans)  and  AnimRotate(arVertics, vRot)

to modity the mesh. arVertics ist an array with the vertics ofthe mesh.
AnimTranslate() simply adds the offset to each vector, AnimRotate() internally
uses "vrotate" to make the rotation.
