Could anyone tell me exacty how the the object coordinate system is derived? What is the relationship between its origin and the world origin? Are its basis vectors (the direction and scale of its x, y, and z) the same as the world's? Just to be sure, by object coordinate system, I mean the parameters passed to an SXP via Sxpdata p[3]. My current guess is that the object coordinate origin is the center of the object's bounding box (as defined in the world coordinate system). Is this right? Thanks in advance, Aaron
