Help function to know a triangle-box intersection

Hi,

I have found a c++ routine to know if a trianle overlapping a box.

http://jgt.akpeters.com/papers/AkenineMoller01/tribox.html

I need a function in blitz who do the same job, but the function use define blitz don't support define like function. Does exist similar b3d function code who return a boolean result when triangle is in contact with a box ?

thanks
