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.

| 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;
