Questions tagged [irrlicht]

Irrlicht is a free open-source cross-platform real-time 3D engine written in C++. The engine is free for open source and commercial use under the zlib/libpng license.

Irrlicht, like others 3D engines (Ogre, Unity, CrystalSpace, …), enables you to create 3D games and programs without having to deal with low level details.

In a few lines of code, you can load a complex mesh created in a 3D modeling software like Blender, apply a texture to it, add some lighting, fog and other visual effects, render it and even animate it.

For a complete description of the features of the engine, checkout the list of features.
