Free ezorb capsules software for linux

OPAL is a high-level interface for low-level physics engines used in games, robotics simulations, and other 3D applications.
Features a simple C++ API, intuitive objects (e.g. Solids, Joints, Motors, Sensors), and XML-based file storage for complex objects.
Main features:
- Open Source
- Cross-platform
- Tested on Linux, Irix, Windows, and Mac OS X
- XML file loading
- OPAL XML exporter for 3ds Max
- Breakable joints
- Linear and angular motion damping
- Per-shape material settings
- Contact groups (define which objects can interact physically)
- Collision detection primitive shapes
- Boxes
- Spheres
- Capsules (i.e. capped cylinders)
- Planes
- User-defined triangular mesh collision detection (best for terrains)
- Joints
- Hinge joints (one rotational degree of freedom)
- Universal joints (two rotational degrees of freedom)
- Ball joints (three rotational degrees of freedom)
- Wheel joints (two rotational degrees of freedom)
- Slider joints (i.e. prismatic joints; one translational degree of freedom)
- Fixed joints (zero degrees of freedom)
- Motors
- Attractor motors (provide gravitational attraction between two objects)
- Geared motors (simplified automobile engines)
- Servo motors (use limited torque to achieve a desired angle or velocity; similar to PD/PID controllers)
- Spring motors (simple damped springs; pull objects to a desired position and/or orientation)
- Thruster motors (provide a constant force on an object)
- Sensors
- Acceleration sensors
- Incline sensors
- Raycast sensors
- Volume sensors
- Event handlers
- Collision event handler (notified when objects collide)
- Joint break event handler (notified when a joint breaks)
- Post-step event handler (notified at the end of each time step)
Enhancements:
- Many bugfixes, unit tests, and enhancements.
- New features: handling a large number of object updates, a new motor, better joint damage monitoring, and enhanced event handling.
- The project has been migrated to Subversion.

Tunnel project is a simple game involving a ball going down a tunnel.

Tunnel is a game in which you control a capsule going down a tunnel, shooting other balls in the way. In the process you should pick up power-ups and avoid collisions with enemy balls coming your way.

During the game, you can fire at other balls. They break into fragments which can damage your capsule, so beware.

If the game is too slow on your computer, try using a lower resolution, either using command line options or by modifying the options files.

Tunnel is free software released under the GPL.

GNU Robbo project is a game ported from the Atari XE/XL.

The player has to rescue Robbo the robot from an unfriendly planet and help him collect all the parts of a capsule so he can go to another level.
