Rigs of Rods is a complex 3D simulator game where you can drive, fly and sail various vehicles using an accurate and unique soft-body physics engine.
Rigs of Rods (also known as RoR), is a truck, car, airplane and boat simulator. You can drive, fly or sail in total freedom in an open environment.
What makes RoR different to most simulators is its unique soft-body physics: vehicles chassis and wheels are simulated in real-time as flexible objects, giving the simulation an extremely accurate behavior, while allowing the vehicles to be simply specified by their structural composition, as a network of interconnected nodes (forming the chassis and the wheels).
Crashing into walls or terrain can permanently deform a vehicle in a realistic manner.
In addition to its unique soft-body physics, RoR also features an advanced flight model based on blade element theory, allowing the accurate simulation of any airplane, base on their physical dimensions and wing airfoils.
RoR also features an accurate buoyancy model based on elemental pressure gradients, enabling boats with complex hulls to move realistically in the swell.

Enhancements
- Fixed redistribuables Fixed SSE incompatibilities Fixed many contents problems

Cocoa 3D Tutorial will provide a Cocoa framework to interface the OpenGL library in a more OO-fashioned style. It is not meant to be the fastest code possible, nor to leverage all the power of OpenGL, but to give developers a easy way to start working in 3D.
NOTE: Cocoa 3D Tutorial is licensed and distributed under the terms of the Artistic License.

Main features:
- A scene tree, with cameras (one for each view) that can be easily positioned and oriented, and lights.
- Object picking, that allows an interactive manipulation of the scene.
- Factory classes for common objects (cube, sphere, cylinder, ...), groups and transformations.
- Basic OpenGL optimizations (e.g. display lists)
- Full support for OpenGL colors and materials.
- Static textures (read from a graphic file or generated from a styled text), animated textures (read from movies), procedural fixed and animated textures (using configurable Perlin 2 & 3D noise).
- Full support for ARB_vertex_program extension, seen as a special type of texture.
- An animator class, that allows to easily add dynamic components to a scene.

Enhancements
- Added StringTexture class
- Added AnimatedProcTexture class
- Added PlainSurface class
- Added InteractiveView class
- Corrected and updated some class behavior
- Updated Tutorials to use new classes
