Perhaps Fred can help you out with STL Trans.

Once upon a time I wrote a vectorized XYZ to STL output program in C.
It worked well, and is perfectly suited to cnc point gathering.
However, it needs a raster (ie perfectly rectangular matrix in
X & Y with the associated Z). A random point cloud won't do for
this program.

Whomever wants a copy (of the source) can email me directly,
and I'll try digging it up.

It is interesting to note that there are actually two ways of
making up the STL triangles from such a matrix. Offsetting
every second row makes a valid STL file which has much much
nicer results than the naive implementation.
