[Paraview] Paraview [3.8.0] goes into infinite loop on using pointSprite with Sphere

[Francois Bertel]

Hi Madhura,

A quick review of the file
ParaView/Plugins/PointSprite/Rendering/Resources/Shaders/Quadrics_vs.glsl
shows it is missing a statement #version 120 at the beginning as
transpose() is defined for GLSL>=1.20.

It does not mean it will fix your issue because your card has to
support GLSL>=1.20. What is your card? what version of GLSL does it
support?

To answer this question, as your are on Windows, download, install and
run glview (latest is 3.22):
http://www.vtk.org/Wiki/VTK_FAQ#Windows

In the main panel, you will see something like:

OpenGL version 3.2  see details

Click on "see details"

You will see a second panel, the second part is called "Report"
One of the first few lines of this report will be about the GLSL
version, for example:

"Shading Language version: 1.50"
