Boolean Operations Between Shells in SLIDE

To create a part relying on Boolean set operations in SLIDE:

1. Use SLIDE to design a part with "union" and "difference" operations
   (between complete watertight shells only).

2. Save as a SIF file.
   For general background see the SIF-web-page at: http://www.cs.berkeley.edu/~ug/sif/

3. Slice the SIF file, outputing an LSIF file:
   You need to remote login onto an SGI machine, for instance "tiramisu"

   cd to CS294/ and make a directory for yourself.
   Use "scp" to copy files to this directory.
   When you are done please remove your files.

   In your directory do:
   /project/cs/sequin/caffe/sif/slicer/slicer.sgi -t 0.01 -of file.lsif -isif file.sif

4. Convert the LSIF file to SSL (the QuickSlice layer contour format)
   /project/cs/sequin/caffe/sif/lsif/glsif.sgi -o file.ssl -l ssl -t file.lsif

   Send this file back to your own working machine using "scp".

5. Review your SSL file with QuickSlice.
   The CS294-3 class can do this on the machines in 349 Soda Hall.
   There is a QuickSlice folder on the desktop.

   For researchers with no access to 349, you may try the following:
   1) Add the following to your path:
   set path=($path /usr/freeware/qs/IRIX6.5/qs/)
   2) ln -s /usr/freeware/qs/IRIX6.5/qs/qs ~/qs
