Hi all,
I am writing a QML application making use of Qt3D for the rendering of 3D objects. In my scene I want to display a stream of QImages, therefore I subclassed Qt3DRender::QPaintedTextureImage to paint the QImage on the texture every time the image changes. I added this texture to a PlaneMesh and place it in the scene. So far so good, this works. Now as a next step, the QImage size AND the position of the PlaneMesh are dynamic. So if i update the QImage and the transform of the PlaneMesh simultaneously, the update of the texture gets delayed (because the real update and upload to GPU happens in a background thread some time later) This leads to constant flickering of the texture which is pretty annoying. So my question: Is there a way to either: 1. Update the texture synchronously so I know that it will be updated in the next frame? 2. Get notified as soon as the texture was updated, so that i can update my transform a little later? Thanks for your support David
