OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible 3D engine written in C++ designed to make it easier and more intuitive for developers to produce applications utilizing hardware-accelerated 3D graphics.

Ogre3D / OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible, multi-platform, open-source 3D rendering engine (as opposed to a game engine) written in C++. It is designed to make it easier and intuitive for developers to produce applications utilizing hardware-accelerated 3D graphics. The class library abstracts the details of using the underlying graphic libraries Direct3D and OpenGL and provides an interface based on world objects and other high level classes.

OGRE is distributed under the MIT license. OGRE SDKs are currently available for Windows, Mac OS X / iOS, Linux, Android and Windows Phone.

Additionally, OGRE has a very active community, and was SourceForge's project of the month in March 2005 and project of the week in April 2013. It has been used in several commercial games such as Ankh, Venetica, Torchlight I + II, Garshasp, Salvation Prophecy as well as in various training and simulation applications.

Threejs: can I show object boundingbox

I'm come from Ogre and C++, and now I'm developing with Threejs. In ogre, for debug, I often use method: Ogre::SceneNode* n = ... n->showBoundingBox(true); Just for debug and test. Is there a similar method in Threejs? I'm using Sprite object.
