Detailed Description

Specialisation of the SceneManager class to deal with indoor scenes based on a BSP tree.

This class refines the behaviour of the default SceneManager to manage a scene whose bulk of geometry is made up of an indoor environment which is organised by a Binary Space Partition (BSP) tree. A BSP tree progressively subdivides the space using planes which are the nodes of the tree. At some point we stop subdividing and everything in the remaining space is part of a 'leaf' which contains a number of polygons. Typically we traverse the tree to locate the leaf in which a point in space is (say the camera origin) and work from there. A second structure, the Potentially Visible Set, tells us which other leaves can been seen from this leaf, and we test their bounding boxes against the camera frustum to see which we need to draw. Leaves are also a good place to start for collision detection since they divide the level into discrete areas for testing. This BSP and PVS technique has been made famous by engines such as Quake and Unreal. Ogre provides support for loading Quake3 level files to populate your world through this class, by calling the BspSceneManager::setWorldGeometry. Note that this interface is made available at the top level of the SceneManager class so you don't have to write your code specifically for this class - just call Root::getSceneManager passing a SceneType of ST_INTERIOR and in the current implementation you will get a BspSceneManager silently disguised as a standard SceneManager.

createRayQuery()

virtual RaySceneQuery* Ogre::BspSceneManager::createRayQuery ( const Ray &  ray, uint32  mask = 0xFFFFFFFF  )

virtual

Creates a RaySceneQuery for this scene manager.

Remarks

This method creates a new instance of a query object for this scene manager, looking for objects which fall along a ray. See SceneQuery and RaySceneQuery for full details.

The instance returned from this method must be destroyed by calling SceneManager::destroyQuery when it is no longer required.

Parameters

ray	Details of the ray which describes the region for this query.
mask	The query mask to apply to this query; can be used to filter out certain objects; see SceneQuery for details.

Reimplemented from Ogre::SceneManager.

virtual IntersectionSceneQuery* Ogre::BspSceneManager::createIntersectionQuery ( uint32  mask = 0xFFFFFFFF )

virtual

Creates an IntersectionSceneQuery for this scene manager.

Remarks

This method creates a new instance of a query object for locating intersecting objects. See SceneQuery and IntersectionSceneQuery for full details.
