Detailed Description

Separate SceneQuery class to query for pairs of objects which are possibly intersecting one another.

Remarks

This SceneQuery subclass considers the whole world and returns pairs of objects which are close enough to each other that they may be intersecting. Because of this slightly different focus, the return types and listener interface are different for this class.

Member Function Documentation

execute() [1/2]

virtual IntersectionSceneQueryResult& Ogre::IntersectionSceneQuery::execute ( void  )

virtual

Executes the query, returning the results back in one list.

Remarks

This method executes the scene query as configured, gathers the results into one structure and returns a reference to that structure. These results will also persist in this query object until the next query is executed, or clearResults() is called. An more lightweight version of this method that returns results through a listener is also available.

execute() [2/2]

virtual void Ogre::IntersectionSceneQuery::execute ( IntersectionSceneQueryListener *  listener )

pure virtual

Executes the query and returns each match through a listener interface.

Remarks

Note that this method does not store the results of the query internally so does not update the 'last result' value. This means that this version of execute is more lightweight and therefore more efficient than the version which returns the results as a collection.

Implemented in Ogre::DefaultIntersectionSceneQuery, Ogre::OctreeIntersectionSceneQuery, Ogre::BspIntersectionSceneQuery, and Ogre::PCZIntersectionSceneQuery.

getLastResults()

virtual IntersectionSceneQueryResult& Ogre::IntersectionSceneQuery::getLastResults ( void  ) const

virtual

Gets the results of the last query that was run using this object, provided the query was executed using the collection-returning version of execute.

clearResults()

virtual void Ogre::IntersectionSceneQuery::clearResults ( void  )

virtual

Clears the results of the last query execution.

Remarks

You only need to call this if you specifically want to free up the memory used by this object to hold the last query results. This object clears the results itself when executing and when destroying itself.

queryResult() [1/2]

bool Ogre::IntersectionSceneQuery::queryResult ( MovableObject *  first, MovableObject *  second  )

virtual

Self-callback in order to deal with execute which returns collection.

Implements Ogre::IntersectionSceneQueryListener.

queryResult() [2/2]

bool Ogre::IntersectionSceneQuery::queryResult ( MovableObject *  movable, SceneQuery::WorldFragment *  fragment  )

virtual

Self-callback in order to deal with execute which returns collection.

Implements Ogre::IntersectionSceneQueryListener.
