<p>Dear all, </p>
<p>I am running a volume rendering script on Amazon EC2 and got the following error message.
</p>
<p>Commend:<br>
</p>
<p>pvbatch --use-offscreen-rendering test_parallel.py </p>
<p><br>
</p>
<p>Error message:<br>
</p>
<p>ERROR: In /root/ParaView-v4.1.0/VTK/Rendering/VolumeOpenGL/vtkOpenGLProjectedTetrahedraMapper.cxx, line 183<br>
vtkOpenGLProjectedTetrahedraMapper (0x438c880): The required extensions are not supported.<br>
<br>
Warning: In /root/ParaView-v4.1.0/VTK/Rendering/OpenGL/vtkOpenGLExtensionManager.cxx, line 750<br>
vtkOpenGLExtensionManager (0x46ff4a0): Attempting to load GL_VERSION_1_3, which is not supported.<br>
<br>
</p>
<p>I guess there is something missing for the OpenGL. I have installed and set up MESA when compiling the Paraview and ran the simple example successfully.
</p>
<p><br>
</p>
<p>The OS is Red Hat Enterprise Linux Server release 6.5 (Santiago). The version of Mesa is 9.2.

<p>Thanks, </p>
