Detailed Description
Provides storage for the sort types to be used
A Qt3DRender::QSortPolicy class stores the sorting type used by the FrameGraph. The sort types determine how drawable entities are sorted before drawing to determine the drawing order. When QSortPolicy is present in the FrameGraph, the sorting mechanism is determined by the SortTypes list. Multiple sort types can be used simultanously. If QSortPolicy is not present in the FrameGraph, entities are drawn in the order they appear in the entity hierarchy.
Member Type Documentation
enum QSortPolicy::SortType
This enum type describes sort types that can be employed
| Constant | Value | Description |
|---|---|---|
Qt3DRender::QSortPolicy::StateChangeCost | ( 1<<0 ) | sort the objects so as to minimize the cost of changing from the currently rendered state |
Qt3DRender::QSortPolicy::BackToFront | ( 1<<1 ) | sort the objects from back to front inverted z order |
Qt3DRender::QSortPolicy::Material | ( 1<<2 ) | sort the objects based on their material value |
