Irrlicht引擎是一个用C++书写的高性能实时的3D引擎，可以应用于C++程序或者.NET语言中。通过使用Direct3D（Windows平台），OpenGL 1.2或它自己的软件着色程序，可以实现该引擎的完全跨平台。尽管是开源的，该Irrlicht库提供了可以在商业级的3D引擎上具有的艺术特性，例如动态的阴影，粒子系统，角色动画，室内和室外技术以及碰撞检测等。-Irrlicht engine is written in C++, a high-performance real-time 3D engine, can be applied to C++ program or. NET language. Through the use of Direct3D (Windows platform), OpenGL 1.2 shader or its own software program, you can realize the full cross-platform engine. Despite being open source, the Irrlicht library offers available in commercial-grade 3D engine that has the art features such as dynamic shadows, particle systems, character animation, indoor and outdoor technology, and collision detection.
