Detailed Description

A DtSpeedTreeModelInstance is a type of model instance that can get created for a DtTreeModel.

A DtSpeedTreeModelInstance exists to return a a null rootNode() and therefore let a DtSpeedTreeForest know to create a SpeedTree instead of a normal tree. DtTreeModels produce "normal" trees which are added to a DtOsgForest however, if the SpeedTree plugin is loaded, then a DtTreeModel creates a DtSpeedTreeModelInstance when a tree is added to a DtSpeedTreeForest. When the model instance is created a DtModelInstanceOwner emits a signal saying so.

Member Function Documentation

virtual bool makVrv::DtSpeedTreeModelInstance::realize ( DtModelDefinition &  definition )

virtual

Attempt to realize a definition.

If the model instance can't realize the definition it should return false. This will return false if the definition doesn't contain a "speedTreeFilename" parameter;

Reimplemented from makVrv::DtModelInstance.

virtual osg::Node* makVrv::DtSpeedTreeModelInstance::rootNode ( )

virtual

Get the model instance's root node. This will always return null.

Reimplemented from makVrv::DtOsgModelInstance.

virtual void makVrv::DtSpeedTreeModelInstance::setVisible ( bool  isVisible )

no-op

Implements makVrv::DtModelInstance.
