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 PySide6.Qt3DRender.Qt3DRender.QSortPolicy([parent=None])
Parameters

parent – PySide6.Qt3DCore.Qt3DCore.QNode

Constructs QSortPolicy with given parent.

PySide6.Qt3DRender.Qt3DRender.QSortPolicy.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 .

Qt3DRender.QSortPolicy.Texture

sort the objects to minimize texture changes.

Qt3DRender.QSortPolicy.Uniform

sort the objects to minimize uniform changes.
