Higher Level Architecture 3D Simulation Viewer is able to join an HLA simulation. The viewer itself is a HLA federate and is therefore able to join the HLA Run Time Infrastructure to display all objects joined in the federation execution. It features 6 camera fields of view, object selection for information querying, camera attachement to any object in any wanted orientation, ability to handle 3DS and MD2 model files and compressed/uncompressed .bmp and .pcx images, ability to parse specific scene information, and efficient resource handling.
RayTraccio uses a fully object-oriented design to achieve readability and ease of adding features. It already supports many shapes (planes, quadrics, and generic polygons up to the fourth degree) and some meta-shapes to do Constructive Solid Geometry (unin, intersection, and difference), many types of textures (with a bunch of meta-textures to mix textures at will), and reflection.
FastVox is an API for volume visualization that can be embedded into OpenGL displays. It features a multi-threaded realtime volume rendering engine which is based on a set of plugins that range from high-speed software-based renderers to hardware-accelerated renderers designed for current generation graphics hardware.
Raydium is a game engine. It provides a set of functions which allows quick and flexible game creation. It features 3D captures, data repositories, in-game live video capture and playback, a themable GUI, networked physics, full Python bindings, and many other things. The main idea is to keep all this as simple as possible.
