Re: Other Scan and capture methods

Perhaps I can add something here:

The hymarc system writes a binary format point cloud (the source for
reading and writing the file is available via our FTP site

Surfacer can read the hyscan binary (as well as that of a number of
other scanners). Surfacer provides tools for creating NURB models
from the point clouds, but this involves significant manual effort. I
don't believe these models are parametric.

We also can provide our customers with software to polygonize the point
clouds, which can be saved in a number of polygon formats including STL
ascii and DXF polyface.

Hope that helps,
