Rigs of Rods

Rigs of Rods (RoR) is a 3D vehicle simulator licensed under the GPLv3. 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 behaviour 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.
 * Scripting support using AngelScript.
 * Based on the OGRE Graphics Engine
