Matali Physics Pro engine introduces an out-of-the-box support for iOS (iPhone, iPad and iPod Touch) via MonoTouch. The Demo for MonoTouch (with full source code) is available only for licensed developers.
Matali Physics Pro engine also introduces support for advanced serialization. All information describing a physics scene elements like objects, contact points, constraints, meshes, materials, lights, cameras and controllers can be serialized to easily parsable XML files (for each of the supported libraries). This serialization allows for easy 'on the fly' save and load physics scenes.
