Dwen is a raytracer written by myself as a set of educational exercises. It is free for others to modify, redistribute, etc, and the writer encourages it to be used for learning purposes. Dwen is written to be as modular as possible, so that core features may be modified/augmented or new features might be added. Dwen was written in the hope that, after the core product was written, time was spent writing features instead of restricting, unnecessary code.
