irrlicht

Open source high performance realtime 3D engine written in C++

The Irrlicht Engine is an open source high performance realtime 3D engine written in C++. It is completely cross-platform, using D3D, OpenGL and its own software renderer, and has all of the state-of-the-art features which can be found in commercial 3d engines. We've got a huge active community, and there are lots of games in development that use the engine. You can find enhancements for Irrlicht all over the web, like alternative terrain renderers, portal renderers, world layers, tutorials, editors, bindings for perl, ruby, python, and so on. And best of all: It's completely free.
