when building a rather complex Qt3D-Scene I needed some 2D-Text that has
a 3D position, is always facing the camera, and fixed in size,
independent of the camera settings.
While looking over the components provided by Qt3D I stumbled across
Text2DEntity and thought about how it can be tweaked ot fulfill my
As all my requirements can be done inside a shader I thought about
whether the QText2DMaterial that is used inside the class can be
replaced by a custom material. But unfortunately the material is not
accessible from outside.
Text2DEntity can be embedded in another class that applies the camera
information to it, but is there an easier solution to this problem?
