[vtk-developers] OpenGL2 and Windows 8.1 - how to disable vtkRenderingOpenGL

[Andrew Maclean]

Ken,
   Thank you for your prompt reply.

Before running CMake, I deleted the whole build directory just to be on the
safe side!

The culprit seems to be VTK_GROUP_WEB it forces the enabling of
vtkRenderingOpenGL instead of vtkRenderingOpenGL2.
So I have disabled this for now.

I then get a successful build if I add a missing header <algorithm> to
vtkCompositePolyDataMapper2.cxx so I will submit a topic for your
consideration.

Regards
    Andrew

What you did sounds fine. Something else must be pulling the old OpenGL in.
Try looking at the cmake configure output for vtkRenderingOpenGL and see if
there is a module requiring it. Typically it looks something like



* vtkjpeg, needed by 2 modules:

vtkIOImage

vtktiff



maybe seeing what modules are requiring it will give you an idea on what
needs to be turned off.



Thanks

Ken

vtkRenderingOpenGL



I thought I might try an OpenGL2 build in Windows 8.1 for VTK.



I keep getting this error:

CMake Error at Rendering/OpenGL/CMakeLists.txt:3 (message):
vtkRenderingOpenGL cannot be built with vtkRenderingOpenGL2, please disable
one of them.



How do I disable vtkRenderingOpenGL?

I deleted the cache and set the VTK_RENDERING_BACKEND variable to OpenGL2,
which I thought would have automatically disabled vtkRenderingOpenGL.



Any advice?



Thanks

   Andrew
