Currently supported platforms are Windows, MacOS X and Linux. Using OpenMesh a variety of file formats are supported ( off, obj, ply, ... ). Additionally OpenFlipper provides a highly flexible interface for creating and testing own geometry processing algorithms. A powerfull scripting language can be used to access all parts of OpenFlipper and modify geometry or the user interface at runtime.
