Thanks. 
I just moved and my hard disk is full to the brim. Wife says no new PC
until we finish unpacking, ie., 2001. Thus, I'm putting off going to POV
3.1 for a while.  I understand a bit of matrix algebra, but not the
following line from the recommended macro.  Is there a 3.02 way to do
this?  

matrix < vX1.x, vY.x,vZ1.x, vX1.y,vY.y,vZ1.y, vX1.z,vY.z, vZ1.z, 0,0,0 >
matrix < vX2.x,vX2.y,vX2.z,  vY.x,vY.y, vY.z, vZ2.x,vZ2.y,vZ2.z, 0,0,0 >

Particularly, what does  vX1.x  mean?  The period confuses me.  I
understand the vcross and vnormalize functions. 
Thanks again.
