X-Plane is a flight simulator that reads in the geometric shape of any aircraft and then figures out how that aircraft will fly. It does this via an engineering process called "blade element theory", which involves breaking the aircraft down into many small elements and then finding the forces on each little element many times per second. These forces are then converted into accelerations, which are then integrated to velocities and positions. This gives X-Plane the most realistic flight model available for personal computers.
Simulum deals with different simulations of star movements and their visualizations. At first it looks at the projection and accumulation of star brightness. In actually doing this it distributes stars among a three dimensional figure. To get a nice effect it combines the photographic image production with a moving view point. So the outcome is the visual impression of flying through a star field. Secondly it studies different algorithms of particle movements and clustering. The primary approach uses a combination of Newton's gravitational law, energy, and impulse conservation. At all these stages an highly dynamic view of the processes is able to be produced.
Motorsport is a project with a clear goal: to create the most realistic vehicle simulation possible. This includes cars and trucks, which can be driven using common input devices such as keyboards and steering wheels. It limits realism to what the hardware, and is intended for hardcore driving simulator fans. This means that it will try to have realistic physics, but not necessarily 'playable', 'easy', or 'fun' physics - these characteristics will depend on which vehicle is driven and on what a person is trying to drive it.
Pizza Game is a 3D, real-time game in which you manage a pizza restaurant. As manager, you must build a restaurant, buy the various objects and furniture that the restaurant requires, hire/fire/manage your employees, buy advertising, buy ingredients, set prices, and make sure your restaurant keeps your customers happy.
"The Game" is a project designed to simplify the process of producing any high-quality cross-platform 2D or 3D graphical computer game. The hope is that any game can be produced simply by changing a few settings and pressing a "compile" button. The project has three "deliverables": a game engine library to abstract across the set of all possible computer games (applying object-oriented design methods to the general problem in such a way as to be usable in specific instances); a graphical interface for easy game design (an exercise in human interface design); and a gaming package with a lot of shiny games to play.
