Detailed Description

PCZ implementation of SphereSceneQuery.

Member Enumeration Documentation

WorldFragmentType

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.

Enumerator
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

execute() [1/2]

void Ogre::PCZSphereSceneQuery::execute ( SceneQueryListener *  listener )

virtual

See SceneQuery.

Reimplemented from Ogre::DefaultSphereSceneQuery.

setStartZone()

void Ogre::PCZSphereSceneQuery::setStartZone ( PCZone *  startZone )

inline

set the zone to start the scene query

setExcludeNode()

void Ogre::PCZSphereSceneQuery::setExcludeNode ( SceneNode *  excludeNode )

inline

set node to exclude from query

execute() [2/2]

virtual SceneQueryResult& Ogre::RegionSceneQuery::execute ( void  )

virtualinherited

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.

setSphere()

void Ogre::SphereSceneQuery::setSphere ( const Sphere &  sphere )

inherited

Sets the sphere which is to be used for this query.

getSphere()

const Sphere& Ogre::SphereSceneQuery::getSphere ( ) const

inherited

Gets the sphere which is being used for this query.

getLastResults()

virtual SceneQueryResult& Ogre::RegionSceneQuery::getLastResults ( void  ) const

virtualinherited

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::RegionSceneQuery::clearResults ( void  )

virtualinherited

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::RegionSceneQuery::queryResult ( MovableObject *  first )

virtualinherited

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

Implements Ogre::SceneQueryListener.

queryResult() [2/2]

bool Ogre::RegionSceneQuery::queryResult ( SceneQuery::WorldFragment *  fragment )

virtualinherited

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

Implements Ogre::SceneQueryListener.

setQueryMask()

virtual void Ogre::SceneQuery::setQueryMask ( uint32  mask )

virtualinherited

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.

getQueryMask()

virtual uint32 Ogre::SceneQuery::getQueryMask ( void  ) const

virtualinherited

Returns the current mask for this query.

setQueryTypeMask()

virtual void Ogre::SceneQuery::setQueryTypeMask ( uint32  mask )

virtualinherited

Sets the type mask for results of this query.

Remarks

This method allows you to set a 'type mask' to limit the results of this query to certain types of objects. Whilst setQueryMask deals with flags set per instance of object, this method deals with setting a mask on flags set per type of object. Both may exclude an object from query results.

getQueryTypeMask()

virtual uint32 Ogre::SceneQuery::getQueryTypeMask ( void  ) const

virtualinherited

Returns the current mask for this query.

setWorldFragmentType()

virtual void Ogre::SceneQuery::setWorldFragmentType ( enum WorldFragmentType  wft )

virtualinherited

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.

getWorldFragmentType()

virtual WorldFragmentType Ogre::SceneQuery::getWorldFragmentType ( void  ) const

virtualinherited

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

getSupportedWorldFragmentTypes()

virtual const std::set<WorldFragmentType>* Ogre::SceneQuery::getSupportedWorldFragmentTypes ( void  ) const

inlinevirtualinherited

Returns the types of world fragments this query supports.
