[vtk-developers] OpenGL backend - 1.1 vs 2.0

[Vladimir Engelgardt]

Hi,

Problem description: Application uses VTK 7.0 (OpenGL 2 module) for
rendering on Windows platform. But the problem is, that OpenGL 2 has limited
support over Microsoft's Remote Desktop. RDP is a must for our application
(VNC, TeamViewer is not an option). On Win 10 there is an option called 'Use
hardware drivers over RDP' and it works, but for limited set of video
adapters - AMD, Integrated Graphics from Intel and NVIDIA (Tesla, Grid
only).

Is there any workaround for this problem, i.e. detect GL version at runtime
and use 1.1 or 2.0? If no, we are going to switch for OpenGL 1.1.

We concern about OpenGL 1.1 support in future versions of VTK. Is it going
to be supported and how long?

Best Regards,
Vladimir.
