STL 3D geometry format parsing and pretty-printing

Latest on Hackage:

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

STL is a simple file format for representing 3D objects as the triangles which form their surface. It is common in 3D printing workflows.

This Haskell library provides parsing and serialization to and from both text and binary STL formats.

Documentation for the last release is on Hackage. The examples directory contains a couple of simple command-line programs using the library.

Bug reports, patches, and examples of use are welcome.
