I'm doing subsurface laser etching in glass blocks. This technology
just plots points in 3D - no lines or surfaces - so it renders point
clouds simply as point clouds, with no need for any more structure.
It's quite nifty really: not very big, but things can be done with the
medium that just aren't on the table with carved or built models.

I personally am more interested in sculptural and scientific models
(there are two at, but I know people who
want to etch scanned portraits and other objects, and I figured this
would be the place to ask.

Thanks to everyone for helpful suggestions!

It seems like all the software that does this is very expensive and
also does a lot of other things not relevant to this application. So
we'll probably end up either getting it done as a service, or with me
writing a wee tool to do the job.
