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 usecases rather than 3D usecases, 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
QSGTransformNode
¶ Create a new
QSGTransformNode
with its matrix set to the identity matrix.

combinedMatrix
()¶  Return type
QMatrix4x4
Set during rendering to the combination of all parent matrices for that rendering pass.

PySide2.QtQuick.QSGTransformNode.
matrix
()¶  Return type
QMatrix4x4
Returns this transform node’s matrix.

setCombinedMatrix
(matrix)¶  Parameters
matrix –
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.
