THE BOX'S MAIN HELP:

All the information in the state pertains to the interpolated
intersection point in a triangle.  This function returns the 
uninterpolated triangle vertices.

TYPE (input):

A character that controls which triple of vectors is to be retrieved.
'p' the points in space
'n' the normal vectors
'm' the motion vectors
't' the texture coordinates of texture space ntex
'u' the U bump basis vectors
'v' the V bump basis vectors

NTEX (input):

The texture space to use when the which parameters is 't'.

A (output):

Returned triangle vector.

B (output):
