%description
Converts data to STL (stereolithography) files that can be used to feed a
3-dimensional printer.  The 3-dimensional output from a function can be
materialized into a solid surface in a plastic material, therefore
allowing more detailed examination. There are many possible uses for this
new tool, such as to examine mathematical expressions with very irregular
shapes, to aid teaching people with impaired vision, to create raised
relief maps from digital elevation maps (DEMs), to bridge the gap between
mathematical tools and rapid prototyping, and many more.  Ian Walker
created the function r2stl() and Jose' Gama assembled the package.
