3D array from surfaces? [message #60408]

Dear IDLers,

Anybody know a simple/sensible way to create a 3D array from a
collection of surfaces?

I have a series of surfaces defined by vertexes in STL files. I need
to make a 3D bit mask with the value of the each element depending on
if the element is inside or outside of each surface - the opposite of
the segmentation process that generated the STL files. This data
comes from external software that uses these bit masks as an
intermediate step, but of course cannot save them since it is obvious
that no one would ever need that intermediate data ;-).

As usual, I'd rather not reinvent the wheel if someone has already put
together reasonably round one...

Mike
