Inheritance diagram for Ogre::SceneQuery:
Public Types | |
enum | WorldFragmentType { WFT_NONE, WFT_PLANE_BOUNDED_REGION, WFT_SINGLE_INTERSECTION, WFT_CUSTOM_GEOMETRY, WFT_RENDER_OPERATION } |
This type can be used by collaborating applications & SceneManagers to agree on the type of world geometry to be returned from queries. More... | |
Public Methods | |
SceneQuery (SceneManager *mgr) | |
Standard constructor, should be called by SceneManager. | |
virtual | ~SceneQuery () |
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. | |
Protected Attributes | |
SceneManager * | mParentSceneMgr |
unsigned long | mQueryMask |
std::set< WorldFragmentType > | mSupportedWorldFragments |
WorldFragmentType | mWorldFragmentType |
Different SceneManagers will implement these queries in different ways to exploit their particular scene organisation, and thus will provide their own concrete subclasses. In fact, these subclasses will be derived from subclasses of this class rather than directly because there will be region-type classes in between.
These queries could have just been implemented as methods on the SceneManager, however, they are wrapped up as objects to allow 'compilation' of queries if deemed appropriate by the implementation; i.e. each concrete subclass may precalculate information (such as fixed scene partitions involved in the query) to speed up the repeated use of the query.
You should never try to create a SceneQuery object yourself, they should be created using the SceneManager interfaces for the type of query required, e.g. SceneManager::createSphereSceneQuery.

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.
