常见的3D引擎有:Unreal、Quake、Lithtech、OGRE、Nebula、Irrlicht、Truevision3D... 其中开源免费的有:OGRE、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 。 Standard OGRE IrrLicht Truevision3D General Type Only rendering engine Game engine IncludeTV3DEngine,TV3DMedia,TV3DNet…… Languages Written in pure C++, totally object orientated.
