QSGTransformNode

The QSGTransformNode class implements transformations in the scene graph. More…

Synopsis

Functions

• def combinedMatrix ()

• def matrix ()

• def setCombinedMatrix (matrix)

• def setMatrix (matrix)

Detailed Description

Transformations apply the node’s subtree and can be nested. Multiple transform nodes will be accumulated by intersecting all their matrices. The accumulation happens as part of the rendering.

The transform nodes implement a 4x4 matrix which in theory supports full 3D transformations. However, because the renderer optimizes for 2D use-cases rather than 3D use-cases, rendering a scene with full 3D transformations needs to be done with some care.

Note

All classes with QSG prefix should be used solely on the scene graph’s rendering thread. See Scene Graph and Rendering for more information.

class PySide2.QtQuick.QSGTransformNode

Create a new QSGTransformNode with its matrix set to the identity matrix.

PySide2.QtQuick.QSGTransformNode.combinedMatrix()

Return type:

PySide2.QtGui.QMatrix4x4

PySide2.QtQuick.QSGTransformNode.matrix()

Return type:

PySide2.QtGui.QMatrix4x4

Returns this transform node’s matrix.

setMatrix()

PySide2.QtQuick.QSGTransformNode.setCombinedMatrix(matrix)

Parameters:

matrix – PySide2.QtGui.QMatrix4x4

Sets the combined matrix of this matrix to transform .

This function is meant to be called by the node preprocessing prior to rendering the tree, so it will not mark the tree as dirty.

PySide2.QtQuick.QSGTransformNode.setMatrix(matrix)

Parameters:

matrix – PySide2.QtGui.QMatrix4x4

Sets this transform node’s matrix to matrix .
