Rigs Of Rods

Rigs of Rods is an open source vehicle simulator based on soft-body physics and licensed under the GNU General Public License version 3.
What makes Rigs of Rods different to most simulators is its unique soft-body physics: vehicles, machines, objects, etc. are simulated in real-time as flexible soft-body objects, giving the simulation an extremely accurate behavior which entirely depends on the physical construction of the vehicles or objects you create.

Features:
- Soft-body physics. Objects according to their weight distribution, construction, and/or suspension (in the case of vehicles).
- Advanced flight model based on blade element theory. It allows the accurate simulation of any airplane, based entirely on its physical dimensions and wing airfoils, similar to X-Plane.
- Accurate buoyancy model based on elemental pressure gradients, enabling boats with complex hulls to move realistically in the swell.
- Basic support for dual-core processing. More multithreading and CUDA support is planned.
- Basic support for scripting using AngelScript.
- Based on the OGRE Graphics Engine
