- * OpenSimplex (Simplectic) Noise in C.
- * Ported to C from Kurt Spencer's java implementation by Stephen M. Cameron
- *
- * v1.1 (October 6, 2014)
- * - Ported to C
- *
- * v1.1 (October 5, 2014)
- * - Added 2D and 4D implementations.
- * - Proper gradient sets for all dimensions, from a
- * dimensionally-generalizable scheme with an actual
- * rhyme and reason behind it.
- * - Removed default permutation array in favor of
- * default seed.
- * - Changed seed-based constructor to be independent
- * of any particular randomization library, so results
- * will be the same when ported to other languages.
