[Paraview] VTK warning during volume rendering of vtkStructuredGrid on Windows with Nvidia graphics card.

[Weiguang guan]

I run into the same problem on linux.

Warning: In 
/home/kitware/dashboards/buildbot/paraview-debian6dash-linux-shared-release_opengl2_qt4_superbuild/source-paraview/VTK/Rendering/VolumeOpenGL2/vtkOpenGLProjectedTetrahedraMapper.cxx, 
line 251
vtkOpenGLProjectedTetrahedraMapper (0x630b310): Missing FBO support. The 
algorithm may produce visual artifacts.

I'm running Paraview 5.0.0.
