常见的3D引擎有：Unreal,Quake,Lithtech,OGRE,Nebula,Irrlicht,Truevision3D...等，其中开源免费的有：orge,irrlicht,fly3d, NeoEngine, revolution3d, Nebula2，Genesis3d等。OGRE 在免费、开源的引擎中评价最高，一个原因是作为一个图形渲染引擎，它支持的图形特性最多，所以渲染质量也不错；另一个原因是设计模式的清晰；另外，速度也不错。OGRE 将专注于向一个纯粹的、然而富于协作和扩展性的图形引擎发展，这得益于它的庞大的社群支持，使得很多事情可以通过外挂一些更专业的引擎来实现，物理引擎使用 ODE 、 Tokamak 、 NovodeX ，网络引擎使用 openTNL 、 RakNet 、 eNet ，声音引擎使用 FMod 、 OpenAL ，以及界面引擎使用 CEGUI 。

|
Materials |
· Powerful material declaration language · Multiple material · Material LOD · Multi-texture and multi-pass blending · Projective texturing · Textures can be provided and updated in real-time by plugins |
· Provide common built in materials based on fixed function pipeline or programmable pipeline · add new materials to Irrlicht at runtime, without the need of modifying/recompiling the engine |
