BRL-CAD provides a couple dozen distinct primitives. Each primitive is defined by a set of parameters. Several of the more complex primitives have a wiki page describing them in more detail with an example on how to create them.

This task involves writing up a page on the VOL primitive. Figure out how to use it (see the ''in'' command, see the EBM tutorial, etc), create an example input data set, and write up a wiki page on exactly what steps are needed similar to our other wiki pages:

• http://brlcad.org/wiki/EBM (particularly useful as the data is similar for VOL)

Show how to create a VOL with at least two layers/slices. Include images like the other examples. Put the write-up at http://brlcad.org/wiki/VOL
