Tootle (Triangle Order Optimization Tool) is a mesh optimization library that improves on existing mesh preprocessing techniques. By using Tootle, developers can optimize their models for pixel overdraw as well as vertex cache performance. This can provide significant performance improvements in pixel limited situations, with no penalty in vertex-limited scenarios, and no runtime cost.

- Support for Windows Vista 64 bits and Linux 32 bits.
- Support for a software only version library (without Direct3D dependency).
- Integrated a new fast optimization algorithm from SIGGRAPH 2007.
- Added new utility functions (TootleOptimize and TootleFastOptimize) to perform the entire Tootle optimization using a single function call.
- Updated old entries with the ability to choose a specific code path for the algorithm (e.g. you can specify using either the DIRECT3D or TIPSY path to optimize vertex cache).
- Updated Tootle Samples with several examples of using the different code paths of the library.
- Updated the documentation. Please read the documentation before using the new Tootle library.
- Fixed several bugs in the old library.
