Hi,

I have two vectors (A and B) which can be considered to be normal vectors
for objects ObjA and ObjB. How do I rotate object ObjB to have its normal B
aligned with the normal A of ObjA? Is this a built-in function in povray? 

Thanks,
gert

#include "transforms.inc"
object {ObjB Reorient_Trans(B,A)}
