The G3D Innovation Engine 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 hardware accelerated 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:

• Multiple rendering modes
  • Hardware-accelerated OpenGL
  • Ray tracing
  • Remote rendering
  • Both forward and deferred shading
• Developer HUD
  • In-engine video recording
  • Camera bookmarks, tone map controls, and splines
  • On-screen performance stats
• Data import and export
  • OBJ, 3DS, STL, STLA, IFS, MD2, MD3, BSP, PLY, PLY2, OFF, and custom models
  • JPG, PNG, BMP, PPM, TIFF, EXR, HDR, PCX, TGA, DDS, and ICO images
  • MP4, MPG, MOV, AVI, DV, QT, and WMV video input and output
  • 1 GB of ready-to-use assets
• Write once, run everywhere
  • Windows 7, Vista, XP, and OS X
  • Visual C++, XCode, llvm, and gcc compilers
  • Java interoperability for file and network classes
• GLSL shader preprocessor with #include, #for, automatic argument binding, and HLSL compatibility
• Easy to use, skinnable GUI with data-bound controls and text rendering
• Optional automatic memory management
• TCP and UDP-based networking with P2P LAN discovery
• Optimized n x m matrix, including inverse and SVD
• Automatic configuration file read/write
• Spline, kd-tree, frustum and other necessary 3D classes
• Included model viewer and Unix build utilities
• 500 pages of reference and overview documentation, plus 9 sample programs

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