Balancer 

Atangeo Balancer is a tool that puts your 3D polygonal models in balance. With Balancer you can quickly and easily find your perfect balance between visual appearance and the number of polygons. Balancer utilizes a high quality polygon reduction (aka mesh simplification) to preserve the visual appearance of your model. The model features, normals, texture coordinates, layer boundaries are all honored. Optimize your models even further to dramatically speed up rendering of your models. Balancer features a fast and efficient triangle reordering that can be tuned for various rendering methods like triangle strips and array/buffer based rendering. Balancer Lite is a free version. It is fully functional but works with small models only. Balancer Demo is also included in the package to evaluate Balancer on large models.
