Detailed Description¶
A
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. WhenQSortPolicy
is present in the FrameGraph, the sorting mechanism is determined by thesortTypes
list. Multiple sort types can be used simultaneously. IfQSortPolicy
is not present in the FrameGraph, entities are drawn in the order they appear in the entity hierarchy.

Description
Qt3DRender.QSortPolicy.StateChangeCost
