Re: 3D printer progress

Graham,
Rhino's SLC export looks broken. I have been able to read the file for
simple forms and export as an ascii file but as soon as the object
gets complicated Rhino starts throwing in bytes here and there. Rhino
always throws in random bytes before the "ffffffff" file terminator.

I even did a GDI renderer that works on simple forms like cubes.

Do you have a source for a "real" SLC file? I don't know where to go
from here.

The decoded ascii for a simple 2x2x2 cube:
