makVrv::DtHeightMapSuperManager Class Reference

A class to manage multiple DtHeightMapManager(s) (one per camera)

In order for heightmaps to be enabled and used, users of this manager should register using addUser(). If there are no active users, then height maps will not be updated. When a user no longer needs height map data, the user should un-register from this manager using removeUser(). See DtTritonDrawable and DtWeatherAreaBlowingSnow for examples of how to register and unregister. Currently, this is a simple reference count.

virtual makVrv::DtHeightMapSuperManager::~DtHeightMapSuperManager ( )

virtual

Destructor.

makVrv::DtHeightMapSuperManager::DtHeightMapSuperManager ( DtDe &  de )

protected

Constructor.

Assignment Operator Not implemented – Assignment Not Allowed.

static DtHeightMapSuperManager& makVrv::DtHeightMapSuperManager::instance ( DtDe &  de )

static

virtual int makVrv::DtHeightMapSuperManager::numHeightMapManagers ( ) const

virtual

returns how many height map managers are owned by this supter manager

virtual osg::View* makVrv::DtHeightMapSuperManager::getCurrentView ( osg::RenderInfo &  renderInfo )

virtual

Extracts the current view from the given RenderInfo that should be associated with a heightmap.

virtual osg::Camera* makVrv::DtHeightMapSuperManager::getViewMainCamera ( osg::View *  view )

virtual

returns the main camera associated with the given RenderInfo view

virtual DtHeightMapManager* makVrv::DtHeightMapSuperManager::findHeightMapCamera ( osg::RenderInfo &  renderInfo )

virtual

find the height map manager based on the current camera for this renderInfo

virtual const DtUniqueID makVrv::DtHeightMapSuperManager::addUser ( const char *  userName )

virtual

Adds a user to this manager. While users are active, the manager will generate/process heightmaps for cameras. A handle id > 0 is returned from this method and the user should unregister using removeUser(handle) when no longer needed. param userName - a name used when reporting errors, useful for debugging returns a handle that should be freed with removeUser when no longer needed.

virtual void makVrv::DtHeightMapSuperManager::removeUser ( const DtUniqueID  handle )

virtual

Removes a user from this manager that was previously added with addUser(). param handle - the handle returned from the call to addUser()

virtual void makVrv::DtHeightMapSuperManager::enableHeightMapManagers ( bool  enable )

protectedvirtual

Ensures that all height map managers are enabled/disabled from the scene graph.

virtual void makVrv::DtHeightMapSuperManager::slot_channelCreated ( DtChannelManager *  channelManager, DtChannel *  channel  )

protectedvirtual

creates height map camera for the channel (scene camera) just created

virtual void makVrv::DtHeightMapSuperManager::slot_channelToBeDestroyed ( DtChannelManager *  channelManager, DtChannel *  channel  )

protectedvirtual

destroys height map camera for the channel (scene camera) to be deleted

virtual void makVrv::DtHeightMapSuperManager::notifyOfReleasedObjects ( )

protectedvirtual

Called from slot_channelToBeDestroyed to notify remaining DtHeightMapManagers that objects have been released.
