If you find bugs, please\nreport them in the \"Issues\" section.\n\nA variant of 2-D noise which is compatible with \"mediump\" 16-bit float precision\nhas been added to the repository. (A 3-D version is more tricky. No promises yet.)\nAs with the WGSL port, bug reports and general feedback on the code is appreciated.\n\nA scientific article on this is published in Journal of Computer Graphics\nTechniques, [JCGT](http://jcgt.org/published/0011/01/02/).\nCode is in the src/ folder, and there are some live WebGL examples and\na tutorial on how to use these functions on\n[the accompanying Github Pages site](https://stegu.github.io/psrdnoise).\n\nPorts to HLSL are in the src/hlsl directory. These were made by @domportera,\nI am not fluent in HLSL myself.\n\nA Unity shader project using another HLSL port of these functions is available\nfrom @chmodseven: https://github.com/chmodseven/psrdnoise\n\nThe infamous troll-owned patent on Simplex Noise finally expired in January 2022,\nbut none of these functions implement any of the patented methods. That patent\nwas arguably never valid in the first place, because I would argue that its\nprimary claim is demonstrably false. In any case, it's a moot point now.\n\n## LICENSE\n\nThe entire content of the docs/ folder is in the public domain, with the\nexception of GLSL shader code that comes with an MIT license as specified\nin the code comments.\n\nAll GLSL code in this repository is published under the permissive\n[MIT license](https://opensource.org/licenses/MIT):\n\nCopyright 2021 Stefan Gustavson and Ian McEwan\n\nPermission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the \"Software\"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
