Aviascene is a virtual environment for remote exploration. Users can download actual earth topography and surface data from USGS, then go exploring. If they get lost, they can launch an aircraft to reconnoiter. It features a high- performance adaptive OpenGL terrain renderer, airplane and wheeled vehicle physics models, and the ability to mark waypoints at GPS coordinates. It can be used to plan a backpacking trip or just as a flight simulator.
Ayam is a free 3D modelling environment for the RenderMan interface. It features good RIB export, CSG (all RenderMan primitives supported), and NURBS modelling. Features instancing, arbitrary number of modeling views, object clipboard, independent property clipboard, n-level undo, console, and Tree-View with Drag-and-Drop support.
BALLView is an extensible viewer for bio-molecular structures. It provides all standard models and offers rich functionality for molecular modeling and simulation, including molecular mechanics methods (AMBER, CHARMM, and MMFF94 force fields), continuum electrostatics methods employing a Finite-Difference Poisson Boltzmann solver, secondary structure calculation, molecular editing and docking. Since BALLView is based on BALL (the Biochemical ALgorithms Library), it is easily extensible on the level of C++ code. In addition, it provides a Python interface with Integrated Development Environment features to allow interactive rapid prototyping.
Balazar is a 3D adventure and roleplaying game which is the sequel to Arkanae. In the game's story, although the three Gods that created the world have been safely imprisoned in the magical crystal of Arkanae, new scepters have been reforged, giving birth to new Gods. The player must find the scepters and imprison the Gods in the Arkanae or free them forever by dropping the scepters in the Abyss. You'll have to find your way through the 7 worlds: the Echassian village, the Pompon forest, the great cathedral, the ice desert, the Arkanae citadel, the Abyss swamp and finally the Elven Forge.
