<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qsgtransformnode.html">QSGTransformNode</a> class implements transformations in the scene graph.</p>
<p>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.</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. See <a href="qtquick-visualcanvas-scenegraph.html#scene-graph-and-rendering">Scene Graph and Rendering</a> for more information.</p></div>
