Scene graph perspective projection
I know that qml engine creates orthogonal projection matrix for openGL to draw the 2d scene. What I want is to define perspective projection matrix multiplied by some camera control matrices that will be used for scene graph. Does anyone know what I should subclass to do that? Qt3D is not an option for me because I want to be able to use usual 2d items like Text and Anchors but make them 3d.
