Detailed Description

BSP specialisation of RaySceneQuery.

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

◆ clearResults()

virtual void Ogre::RaySceneQuery::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.

◆ execute() [1/2]

bool Ogre::DefaultRaySceneQuery::execute	(	ObjectData	objData,
		size_t	numNodes,
		RaySceneQueryListener *	listener
	)

inherited

◆ execute() [2/2]

void Ogre::BspRaySceneQuery::execute ( RaySceneQueryListener * listener )

virtual

See RaySceneQuery.

Reimplemented from Ogre::DefaultRaySceneQuery.

◆ getLastResults()

virtual RaySceneQueryResult& Ogre::RaySceneQuery::getLastResults ( void )

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.

◆ getMaxResults()

virtual ushort Ogre::RaySceneQuery::getMaxResults ( void ) const

virtualinherited

Gets the maximum number of results returned from the query (only relevant if results are being sorted)

◆ getQueryMask()

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

virtualinherited

Returns the current mask for this query.

◆ getRay()

virtual const Ray& Ogre::RaySceneQuery::getRay ( void ) const

virtualinherited

Gets the ray which is to be used for this query.

◆ getSortByDistance()

virtual bool Ogre::RaySceneQuery::getSortByDistance ( void ) const

virtualinherited

Gets whether the results are sorted by distance.

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

inlinevirtualinherited

Returns the types of world fragments this query supports.

◆ getWorldFragmentType()

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

virtualinherited

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

◆ queryResult() [1/2]

bool Ogre::RaySceneQuery::queryResult	(	MovableObject *	obj,
		Real	distance
	)

virtualinherited

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

Implements Ogre::RaySceneQueryListener.

◆ queryResult() [2/2]

bool Ogre::RaySceneQuery::queryResult	(	SceneQuery::WorldFragment *	fragment,
		Real	distance
	)

virtualinherited

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

Implements Ogre::RaySceneQueryListener.

◆ 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. The default initial query mask of a SceneQuery is SceneManager::QUERY_ENTITY_DEFAULT_MASK

Note: By default, Ogre uses @SceneManager::QUERY_ENTITY_DEFAULT_MASK and Co. to set each type of MovableObject's default query mask. This behavior can be overriden though, just set the masks you don't need to 0 before creating those objects.

◆ setRay()

virtual void Ogre::RaySceneQuery::setRay ( const Ray & ray )

virtualinherited

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

◆ setSortByDistance()

virtual void Ogre::RaySceneQuery::setSortByDistance	(	bool	sort,
		ushort	maxresults = `0`
	)

virtualinherited

Sets whether the results of this query will be sorted by distance along the ray.

Remarks: Often you want to know what was the first object a ray intersected with, and this method allows you to ask the query to sort the results so that the nearest results are listed first.

: Note that because the query returns results based on bounding volumes, the ray may not actually intersect the detail of the objects returned from the query, just their bounding volumes. For this reason the caller is advised to use more detailed intersection tests on the results if a more accurate result is required; OGRE uses bounds checking in order to give the most speedy results since not all applications need extreme accuracy.

Parameters

sort	If true, results will be sorted.
maxresults	If sorting is enabled, this value can be used to constrain the maximum number of results that are returned. Please note (as above) that the use of bounding volumes mean that accuracy is not guaranteed; if in doubt, allow more results and filter them in more detail. 0 means unlimited results.

◆ 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.
