Inheritance diagram for Ogre::OctreeCamera:

Ogre::Camera Ogre::Frustum Ogre::MovableObject Ogre::Renderable Ogre::ShadowCaster Ogre::AnimableObject

List of all members.

Detailed Description

Specialized viewpoint from which an Octree can be rendered.
This class contains several specializations of the Ogre::Camera class. It implements the getRenderOperation method in order to return displayable geometry for debugging purposes. It also implements a visibility function that is more granular than the default.
