   Rotation
  Hi, Okay i'm back with a much simpler issue i believe.  Everything is working in my little "engine".  All transformation controls work except for rotations.The rotations themselves are accurate and working properly, except the orbit points are off.Now, How do I rotate an object from a given Orbit Point.  In other words, when I export from 3ds Max, How do I know, or how do I program the rotation of an object that is NOT centered in world space, and has an orbit point at any place.   
  Hum, I'm not 100% sure but how about you translate your world to the orbit, rotate arround the world center and un-translate back to the original position ?Janta   ;  Hi, yep, simple and correct.  It works.
