The techniques described in these notes have been implemented in tangere, an open source, cross-platform, template-based integer/floating-point, Whitted-style ray tracing system. tangere is intended to serve as a testbed for additional enhancements and further experimentation with integer ray tracing techniques.
Additionally, read-only access to the tangere development repository is available via HTTP with git:
git clone http://www.rtvtk.org/code/tangere.git
The README includes instructions for building and running tangere on *NIX and Windows systems. The source code is distributed under the Apache License, version 2.0; please see the LICENSE file that accompanies the source distribution for details.
