cloth simulation

Play around with clothing properties. Design anything from super-elastic to stiff clothings. See the difference between Verlet and Euler integration.
For more information about physics of cloth simulation see the modeling part (springs).
Download cloth example, additionally download nativeG.

bouncing things

See the physics of colliding balls. Start the application with hundreds of balls and watch them interact or start it as a billard demo. Switch on/off gravity and friction.
Information about rigid body collision and physics is provided in the modeling section.
Download bouncing things, additionally download nativeG.

car lab

A simple car physics lab. Springs, damping, alteration of load. Change the mass of the car, the damping and stiffness of the springs and speed up or break.
Information about car physics is provided in the modeling section.
Download car lab, additionally download nativeG.

terrain rendering

A simple terrain renderer based on geo-mipmapping. Since there exists very well documented sites on geo mipmapping and roaming in refer you to google for 'roaming' or 'geomipmapping', or have a look at Geo-Mipmaps at flipcode for more information.
