The IVL product includes some sample code to use as a learning tool. The
/opt/graphics/IVL/demo directory contains files and data that
demonstrate many of the features of IVL. There are smaller example programs
in the /opt/graphics/IVL/examples directory.
README files in these directories describe how to make and run the
programs. (Remember that the example code that ships with IVL is in a
read-only part of the file system. You should copy those files elsewhere
before modifying and/or compiling them.)
