Constructor & Destructor Documentation

◆ Graphic3d_StructureManager()

Graphic3d_StructureManager::Graphic3d_StructureManager ( const Handle< Graphic3d_GraphicDriver > &  theDriver)

Initializes the ViewManager. Currently creating of more than 100 viewer instances is not supported and leads to InitializationError and initialization failure. This limitation might be addressed in some future OCCT releases. Warning: Raises InitialisationError if the initialization of the ViewManager failed.

◆ ~Graphic3d_StructureManager()
