Easy Mesh Simplification

  

Although not as relevant today as it was back in the 90s, to maintain a good frame rate in 3D interactive programs it often necessary render objects using fewer polygons.  Here you will find a simple technique that is fairly fast, and generates reasonably good low-poly models.

Try the demo by running bunnylod.exe.   However, you probably don't want to run some exe file from the internet.  So, try fetching bunnylod.zip which also includes the original source code. Or get revised code from 2014 at: https://github.com/melax/sandbox 

For a nice intorduction and all the details about the algorithm see the full article as featured in Game Developer Magazine.
