Public Methods

 DefaultIntersectionSceneQuery (SceneManager *creator)
 ~DefaultIntersectionSceneQuery ()
void execute (IntersectionSceneQueryListener *listener)
 See IntersectionSceneQuery.

virtual IntersectionSceneQueryResultexecute (void)
 Executes the query, returning the results back in one list.

virtual IntersectionSceneQueryResultgetLastResults (void) const
 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.

virtual void clearResults (void)
 Clears the results of the last query execution.

bool queryResult (MovableObject *first, MovableObject *second)
 Self-callback in order to deal with execute which returns collection.

bool queryResult (MovableObject *movable, SceneQuery::WorldFragment *fragment)
 Self-callback in order to deal with execute which returns collection.

virtual void setQueryMask (unsigned long mask)
 Sets the mask for results of this query.

virtual unsigned long getQueryMask (void) const
 Returns the current mask for this query.

virtual void setWorldFragmentType (enum WorldFragmentType wft)
 Tells the query what kind of world geometry to return from queries; often the full renderable geometry is not what is needed.

virtual WorldFragmentType getWorldFragmentType (void) const
 Gets the current world fragment types to be returned from the query.

virtual const std::set< WorldFragmentType > * getSupportedWorldFragmentTypes (void) const
 Returns the types of world fragments this query supports.

Detailed Description

Default implementation of IntersectionSceneQuery.

Member Enumeration Documentation

enum Ogre::SceneQuery::WorldFragmentType [inherited]
 

This type can be used by collaborating applications & SceneManagers to agree on the type of world geometry to be returned from queries.

Not all these types will be supported by all SceneManagers; once the application has decided which SceneManager specialisation to use, it is expected that it will know which type of world geometry abstraction is available to it.

Enumeration values:
WFT_NONE  Return no world geometry hits at all.
WFT_PLANE_BOUNDED_REGION  Return pointers to convex plane-bounded regions.
WFT_SINGLE_INTERSECTION  Return a single intersection point (typically RaySceneQuery only).
WFT_CUSTOM_GEOMETRY  Custom geometry as defined by the SceneManager.
WFT_RENDER_OPERATION  General RenderOperation structure.

Member Function Documentation

void Ogre::IntersectionSceneQuery::clearResults void    [virtual, inherited]
 

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.

Definition at line 292 of file OgreSceneQuery.cpp.

Referenced by Ogre::IntersectionSceneQuery::execute(), and Ogre::IntersectionSceneQuery::~IntersectionSceneQuery().

IntersectionSceneQueryResult & Ogre::IntersectionSceneQuery::execute void    [virtual, inherited]
 

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.

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.

unsigned long Ogre::SceneQuery::getQueryMask void    const [virtual, inherited]

SceneQuery::WorldFragmentType Ogre::SceneQuery::getWorldFragmentType void    const [virtual, inherited]
 

Gets the current world fragment types to be returned from the query.

void Ogre::SceneQuery::setQueryMask unsigned long    mask [virtual, inherited]
 

Sets the mask for results of this query.

Remarks:
This method allows you to set a 'mask' to limit the results of this query to certain types of result. The actual meaning of this value is up to the application; basically MovableObject instances will only be returned from this query if a bitwise AND operation between this mask value and the MovableObject::getQueryFlags value is non-zero. The application will have to decide what each of the bits means.

void Ogre::SceneQuery::setWorldFragmentType enum WorldFragmentType    wft [virtual, inherited]
 

Tells the query what kind of world geometry to return from queries; often the full renderable geometry is not what is needed.

Remarks:
The application receiving the world geometry is expected to know what to do with it; inevitably this means that the application must have knowledge of at least some of the structures used by the custom SceneManager.

The default setting is WFT_NONE.
