Rigs of Rods (“RoR”) is an open source, freeware, multi-simulation game which uses soft-body physics to simulate the motion and deformation of trucks. The game is built using a specific soft-body physics engine called Beam, which simulates a network of interconnected nodes (forming the chassis and the wheels) and gives the ability to simulate deformable objects. With this engine, trucks flex and deform as ride the terrain, which can be based on real terrain elevation data. Crashing into walls or terrain can permanently deform a vehicle.
- [advt]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
