[vtkusers] [Paraview] GPU based volume rendering in ParaView

[Aashish Chaudhary]

Eric,

Yes you do need to have certain extensions. Now the mapper I have not
written myself and hence I am forwarding this email to vtk users list. I
hope that the original author would respond to it.

I will see if we can produce a better message which could list the missing
extensions.

Thanks for testing it out.

~Regards,
Aashish
