G3D is a commercial-grade 3D Engine available as Open Source (BSD License). It is used in games, tech demos, research papers, military simulators, and university courses. It can support real-time rendering, off-line rendering, back-end game server management of 3D worlds, and use of graphics hardware for general purpose computing.

Supported Features


  • Object-Oriented Design 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 gives you a rock-solid, highly optimized base from which to build your application.
  • Fixed-function
  • Render-to-Texture

  • Environment Mapping
  • Lens Flares
  • Billboarding
  • Particle System
  • Sky
  • Water
  • Fire
  • Explosion
  • Fog
  • Mirror The rendering contains both fixed function and pixel shader 2.0 pipelines. The PS2.0 pipeline contains parallax mapping, bloom, specular mapping, reflections, correct transparency, soft shadows, and other rendering effects.


  • Volumetric


  • Shadow Mapping
  • Projected planar
  • Shadow Volume

Great graphics engine

It is a very good cross platform graphics engine.

The best aspect about G3D is that it is quick and easy to compile without any bugs. Unfortunately, there is little documentation, at least currently. However, the developers provided a lot of help. I am using G3D instead of other engines because it doesn't take away control of the underlying rendering in OpenGL (or Direct3D). Instead, it provides classes and functions that assist you in such things as rotations, loading models, etc. that you wouldn't want to waste time writing yourself.

If you want to do other game engine functions, such as GUI or physics, than you will have to download utility libraries. G3D does provide cross platform networking though. Whether you want one game engine that provides everything, or want to mix and match libraries demends on your personal choice.

Having tried many other game and graphics engines, I strongly recommend G3D.
