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 Member Functions | |
SceneQuery (SceneManager *mgr) | |
Standard constructor, should be called by SceneManager. | |
virtual | ~SceneQuery () |
virtual uint32 | getQueryMask (void) const |
Returns the current mask for this query. | |
virtual uint32 | getQueryTypeMask (void) const |
Returns the current mask for this query. | |
virtual const std::set< WorldFragmentType > * | getSupportedWorldFragmentTypes (void) const |
Returns the types of world fragments this query supports. | |
virtual WorldFragmentType | getWorldFragmentType (void) const |
Gets the current world fragment types to be returned from the query. | |
virtual void | setQueryMask (uint32 mask) |
Sets the mask for results of this query. | |
virtual void | setQueryTypeMask (uint32 mask) |
Sets the type mask for results of 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. | |
A class for performing queries on a scene.
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. |
Ogre::SceneQuery::SceneQuery | ( | SceneManager * | mgr | ) |
