A mesh decimation library for .NET and Unity. The project is written entirely in C# and released under the MIT license.

Before you open up the Visual Studio project you must first make sure that you have a UNITY_HOME environment variable set to the Unity Editor installation directory (for example C:\Program Files\Unity\Editor on Windows or /Applications/Unity/Unity.app on OSX).

This project is currently compatible with Unity 5.5.X and 5.6.X

While it might work with other versions of Unity, this will be the officially supported Unity versions.

After building the project, copy over MeshDecimator.dll, MeshDecimator.xml, MeshDecimator.Unity.dll and MeshDecimator.Unity.xml into your Unity project, anywhere within your Assets directory (for example Assets/MeshDecimator). Now copy over MeshDecimator.UnityEditor.dll to the same directory and make sure to make it available only within the Unity Editor in the Plugin Inspector, or place it within the Editor special directory (for example Assets/MeshDecimator/Editor).

MeshDecimator uses an algorithm based on the Fast Quadric Mesh Simplification algorithm, completely rewritten in C#. Currently it is the only mesh decimation algorithm available to use.
