Disclaimer

This is an unofficial implementation based on the paper "Procedural Stochastic Textures by Tiling and Blending" by Thomas Deliot and Eric Heitz. This implementation only includes the tiling part of the original paper. The blending part is not implemented. The majority of the code was developed with assistance from GPT-4.
