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" On Sat, Jul 10, 2010 at 10:13 AM, Madhura Phadke <[email protected]> wrote: > Paraview Version: 3.8.0 > Plugin: pointSprite plugin > OS: Windows 7, 32 bit. > I recently started using paraview, and whenever I try to use PointSprite > plugin with Sphere mode [I use a point source with 500 points, and change > point sprite mode to 'Sphere'] , I get the error "In > ..\..\..\src\VTK\Rendering\vtkShaderProgram2.cxx, line 450 vtkShaderProgram2 > (0BF67D38): a shader failed to compile". > The error log that got generated can be viewed > from http://cid-bf4825315fd31e46.skydrive.live.com/redir.aspx?resid=BF4825315FD31E46!151&Bpub=SDX.Docs&Bsrc=GetSharingLink. > I found a similar issue in the September 2009 mailing list archive > [http://www.paraview.org/pipermail/paraview/2009-September/013883.html].
