[vtkusers] how to fix this problem:Extension GL_VERSION_1_2 could not be loaded

[Doug Hoppes]

Hi... This is Doug.  Just wanted to chime in on this.

We have the same issue and we're doing volume rendering.  We also seem to have a number of other issues with the NVidia graphics card (out of memory, lines on the image, etc).

Also,

I need to know if your application is doing volume rendering or geometry rendering. The problem is that the code for checking extensions is not updated and not quite right either.

Same problem here.

VTK 6.0.0
Nividia GeForce GT 630  (with newest driver (version 331.65, released 7/Nov/13) supposedly supporting OpenGL 4.4).

I see. Ok, I think I know where its coming from.

Quick question: How it affects your program? Is it just the message or or a real problem for you?

Its better to provide complete information. What are you trying to accomplish in the code? What is your hardware / software (VTK version)

Thanks,
