Rough way to do it explained below:
- If you already have a pointer on the pfGroup you d like to trans/rot/scale,
you may insert just below a pfDCS node you keep a global pointer to.
- The pfDCS will default to 0 rot, 0 translation and 1 scale.
- Then in your postdraw call back, adjust the pfDCS rot/trans/scale.

The node lookup routine must be called just after the scene loading. I don t
know the obj file format, you must have a name for each node and you ve used a
pfuTraverser ???
