+# FastNoise
+
+This is the C# version of [FastNoise](https://github.com/Auburns/FastNoise)
+
+FastNoise is an open source noise generation library with a large collection of different noise algorithms. This library has been designed for realtime usage from the ground up, so has been optimised for speed without sacrificing noise quality.
+
+This project started when my search to find a good noise library for procedural terrain generation concluded without an obvious choice. I enjoyed the options and customisation of Accidental Noise Library and the speed of LibNoise, so many of the techniques from these libraries and the knowledge I gained from reading through their source has gone into creating FastNoise.
+
+I have now also created [FastNoise SIMD](https://github.com/Auburns/FastNoiseSIMD), which utilises SIMD CPU instructions to gain huge performance boosts. It is slightly less flexible and cannot be converted to other languages, but if you can I would highly suggest using this for heavy noise generation loads.
+

+## FastNoise Preview
+
+I have written a compact testing application for all the features included in FastNoise with a visual representation. I use this for development purposes and testing noise settings used in terrain generation.

+Download links can be found in the [Releases Section](https://github.com/Auburns/FastNoise/releases).
