+__WARNING:__ This repository has been archived in favor of [UnityMeshSimplifier](https://github.com/Whinarn/UnityMeshSimplifier), which includes a more updated version of this algorithm for the [Unity game engine](https://unity.com/). This means that I'm dropping the .NET support outside of Unity due to not having the time to maintain two libraries that includes almost the same code. Anyone who wishes to continue on this project is free to do so under the current [license](https://github.com/Whinarn/MeshDecimator/blob/master/LICENSE.md).
