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. When QSortPolicy is present in the FrameGraph, the sorting mechanism is determined by the sortTypes list. Multiple sort types can be used simultaneously. If QSortPolicy is not present in the FrameGraph, entities are drawn in the order they appear in the entity hierarchy.

class SortType

This enum type describes the available sort types.

Constant	Description
Qt3DRender.QSortPolicy.StateChangeCost	sort the objects so as to minimize the cost of changing from the currently rendered state
Qt3DRender.QSortPolicy.BackToFront	sort the objects from back to front based on inverted z order. More accurately, the sorting key is the z component of the projection of the camera-to-object-center vector onto the camera’s view vector.
Qt3DRender.QSortPolicy.Material	sort the objects based on their material (shader) value.
Qt3DRender.QSortPolicy.FrontToBack	sort the objects from front to back. The opposite of BackToFront.
Qt3DRender.QSortPolicy.Texture	sort the objects to minimize texture changes.
Qt3DRender.QSortPolicy.Uniform	sort the objects to minimize uniform changes.
