The default camera and world coordinate systems in RenderMan are left-handed.   
This is fine for the animation types, but bogus for engineers.  So I want to  
draw something that extends out the x-axis, and I want it to have the correct  
relationship (from an engineering view) with the y and Z axes.  Currently, all  
our pictures are backwards.

The problem is, I can't figure out how to do it using the 3Dkit.  Can someone  
give me the appropriate call and where to put it?  We think we have tried all  
the obvious things based on The RenderMan Companion, but I think this  
functionality gets "in between" the differences between the OO NeXT  
implementation and the procedural TRC discussion.

Thanks in advance.
