Detailed Description

PCZ implementation of IntersectionSceneQuery.

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::IntersectionSceneQuery::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]

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

See IntersectionSceneQuery.

Reimplemented from Ogre::DefaultIntersectionSceneQuery.

◆ execute() [2/2]

virtual IntersectionSceneQueryResult& Ogre::IntersectionSceneQuery::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.

◆ getLastResults()

virtual IntersectionSceneQueryResult& Ogre::IntersectionSceneQuery::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.

◆ getQueryMask()

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

Returns the current mask for this query.

◆ getSupportedWorldFragmentTypes()

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.

◆ operator delete() [1/3]

void Ogre::AllocatedObject< Alloc >::operator delete ( void *  ptr)

◆ operator delete() [2/3]

const char *   
)

◆ operator delete() [3/3]

template<class Alloc >
void Ogre::AllocatedObject< Alloc >::operator delete ( void *  ptr,
void *   
)
inlineinherited

◆ operator delete[]() [1/2]

template<class Alloc >
void Ogre::AllocatedObject< Alloc >::operator delete[] ( void *  ptr)
inlineinherited

◆ operator delete[]() [2/2]

template<class Alloc >
void Ogre::AllocatedObject< Alloc >::operator delete[] ( void *  ptr,
const char *  ,
int  ,

)

◆ operator new() [2/3]

template<class Alloc >
void* Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz,
const char *  file,
int  line,
const char *  func 
)
inlineinherited

operator new, with debug line info

◆ operator new() [3/3]

template<class Alloc >
void* Ogre::AllocatedObject< Alloc >::operator new ( size_t  sz,
void *  ptr 
)
inlineinherited

placement operator new

◆ operator new[]() [1/2]

template<class Alloc >
void* Ogre::AllocatedObject< Alloc >::operator new[] ( size_t  sz)
inlineinherited

◆ operator new[]() [2/2]

template<class Alloc >
void* Ogre::AllocatedObject< Alloc >::operator new[] ( size_t  sz,
const char *  file,
int  line,
const char *  func 
)
inlineinherited

array operator new, with debug line info

◆ queryResult() [1/2]

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

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 
)
virtualinherited

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

Implements Ogre::IntersectionSceneQueryListener.

◆ 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.

◆ 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.
