Multiple transform nodes will be accumulated by intersecting all their matrices. The accumulation happens as part of the rendering.</p> <p>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.</p> <p><b>Note: </b>All classes with QSG prefix should be used solely on the scene graph's rendering thread.
