VR Flight Simulator with real world scenery and new aircraft
Cosmosair Flight Simulator (Cosmosair FS) is the next generation virtual reality (VR) flight simulator aimed mainly at x64bit computer systems (MacOSX, Windows, Linux) that integrates a 360º Degrees VR Engine. It comes packed with first-class Up-to-Date World Scenery and State-of-the-Art 3D Aircraft Models. It allows you to fly into Space and back to the Earth seamlessly. You can fly to Mars within it's atmosphere and explore it's landscape... or even fly and land on the Moon. You can perform orbital space flights near our earth or in far planets. With Cosmosair FS you can become a better pilot flying commercial airliners or military aircraft. You can do pre-established missions, set your own missions or discover the solar Sytem planet by planet with NASA's Shuttle or SciFi Spacecraft. Cosmosair FS comes packed with top-notch features that sets it apart from it's counterpart flight simulators. CosmosairFS is under active development and will be soon unveiled.
Simone (or Simulation One) is a simulation platform for global markets and the enterprise. Suitable for training, education, and gaming, it provides a central networked simulation that is both complete and extensible.
The Objective-C Interactive Simulation Abstraction Layer
SimKit(because GameKit was taken) is designed to allow quick and easy cross platform abstraction away from platform dependant drawing and physics libraries. The APIs provide a generic way to make common calls for drawing, animating, and otherwise manipulating 3D entities, as well as shading and texture information.
This is the project I created to support the iPhone version of Box2D. It uses Cocos2D to do the drawing. Only rectangles, circles, and distance joints are supported. Instructions are in the readme.
