[PD] position of object with rotation

[philippe boisnard]

Hello

I work to create a sceleton and I ahave problem with arm and legs

When we use a .obj, we have only 1 entry to détermine the position [translate or rotate], and not 2. The position is the base of the objetct.
I search to determine the vertex position from the coordinate of a specific point, that I move. It therefore requires a rotation [XYZ] of the object from its base. 

I can't do. 


Ant idea ?
