G3D is a commercial-grade C++ 3D engine available as Open Source (BSD License). It is used in commercial games, research papers, military simulators, and university courses. G3D supports real-time rendering, off-line rendering like ray tracing, and general purpose computation on GPUs.

G3D provides a set of routines and structures so common that they are needed in almost every graphics program. It makes low-level libraries like OpenGL and sockets easier to use without limiting functionality or performance. G3D is a rock-solid, highly optimized base on which to build your 3D application.

Major features include:

• 3DS, IFS, MD2, BSP, and custom models
• JPG, PNG, BMP, PPM, PCX, TGA, DDS, and ICO images
• Runtime debugging tools
• Skinnable GUI
• Font rendering
• Shaders
• Shadow maps and shadow volumes
• Optional automatic memory management
• TCP and UDP-based networking
• Optimized n x m matrix, including inverse and SVD
• Windows, OS X, Linux, and FreeBSD supported
• Visual C++, XCode, and gcc compatible
• Configuration file read/write
• Java file and network classes
• Tools: Model viewer, GPU benchmark, and build utilities

The development team spans the graphics industry. It includes professional game developers, military and contractors, PhDs, students, and professors.
