|
| |
| virtual void | AddZLayer (const Graphic3d_ZLayerId theLayerId)=0 |
| | Add a new top-level z layer with ID <theLayerId> for the view. Z layers allow drawing structures in higher layers in foreground of structures in lower layers. To add a structure to desired layer on display it is necessary to set the layer ID for the structure. More...
|
| |
| virtual void | RemoveZLayer (const Graphic3d_ZLayerId theLayerId)=0 |
| | Removes Z layer. All structures displayed at the moment in layer will be displayed in default layer (the bottom-level z layer). By default, there are always default bottom-level layer that can't be removed. The passed theLayerId should be not less than 0 (reserved for default layers that can not be removed). More...

| |
| Standard_Transient * | This () const |
| | Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. More...
|
