I have a fairly complex GUI for the manipulation of 3D models which have experimental data interpolated onto their surfaces from a discrete set of experimental data. I need to label the locations at which the experimental data is measured. I do this by doing a plot3(...) of the data point locations, and then a text(...) of the label of interest at each point.
My problem however is that the text does not render correctly on top of the 3D geometry. It is almost good, except that the text is half clipped or fully clipped by the 3D geometry depending on camera angle. I haven't found a solution to this online. People suggest uistack and other methods but none of those work in this case. Moving the data points above the patch geometry is also not an option, because the geometry is highly complex and this cannot be generalised.
Does anybody know of some kind of low level OpenGL tweak I can use in Matlab to force the text to be rendered closer to the front of the screen than any patch object that it is deemed to coincide with? I do not particularly want to use annotate() since it uses figure coordinates which will cause a lot of headaches downstream in the GUI.
Thanks
