<p>Hi Aashish,</p>
<p> </p>
<p>This machine is running Windows 7. I built Paraview v5.0.0-RC2 with Visual Studio 2015.
</p>
<p> </p>
<p>GLview does list GL_ARB_framebuffer_object as supported. Are there any other specific features in the report that I should check? </p>
<p> </p>
<p>Best,</p>
<p>Steven</p>

<div dir="ltr">Hi Steven,
<div><br>
</div>
<div>Also, can you install and run glview (<a href="http://www.realtech-vr.com/glview/download.php">http://www.realtech-vr.com/glview/download.php</a>) on your system to see if FBO support exists? </div>
<div><br>

<div>Thanks,</div>

I tried viewing the volume representation of a small vtkStructuredGrid<br>
file with ParaView v5.0.0-RC2 built with the OpenGL2 rendering backend and<br>
get this warning:<br>
<br>
Warning: In<br>
C:\Sources\ParaView-v5.0.0-RC1-source\VTK\Rendering\VolumeOpenGL2\vtkOpenGL<br>
ProjectedTetrahedraMapper.cxx, line 251<br>
vtkOpenGLProjectedTetrahedraMapper (00000000061B0AD0): Missing FBO<br>
support. The algorithm may produce visual artifacts.<br>
<br>
Updating the video card (Nvidia Quadro K6000) driver to the latest version<br>
(354.56) had no effect. Volume rendering with a different vtkImageData<br>
file generated no warnings.<br>

<div>They are using different mappers. I am surprised that you are reported missing fbo support. Which windows Platform is this? </div>
