Fountain 3D is a little J2ME toy and a technology demo for a custom-made 3D wireframe engine with some benchmarking abilities thrown in. The camera is fully controllable by the user together with the simple particle simulation. The software doesn't require hardware acceleration; all J2ME compliant mobiles are supported.
wiiFrame is a simple GUI frame that has an OpenGL 3D window and a dialog box that connects Nintendo Wii remotes to the application. This is to be used as a basis for anyone who wants to write 3D applications that are controled by a Wii remote. This project uses wxWidgets, so it can be compiled cross platform, but as of now, only a Linux build works.
The Simulus Game Engine is a cross-platform, flexible, and easy-to-use game engine. It is capable of running on Windows and Linux and can support multiple APIs for rendering, audio, etc. It is built to be as flexible as possible to the advanced programmer while still maintaining ease of use for the beginning programmer. File formats are XML-based. It currently supports OpenGL rendering with meshes, lighting, texturing, scenes, cameras, and sprites.
Raja (RAy tracer in JAva) is a complete, object oriented ray tracer written in Java. It fully supports transparency, intersection, union, complement, mirroring, basic anti-aliasing, and exact acne correction. We aim to do a complete, easy to use and distributed renderer to do images or movies over a network of heterogeneous computers.
The Deimos Project is a 3D space combat simulator and modular game library collection. It includes a 3D modeler designed with a programmer's needs in mind. It allows you to construct 3D models by writing Java source code. All you need to design a model is a computer, some graph paper, and a pencil. The modeler's internals function as a simple OpenGL scene graph API, without preventing the use of low-level OpenGL commands. For storing settings and other hierarchically-representable data, the project provides a Hierarchy library that stores data atomically using XML. It also features a timing library, a game object container system, and many other features.
