[vtkusers] WebGL 3D Viewer Demo

[Sebastien Jourdain]

Hi Sathish,

Nice work !

I was wondering if you took a chance to try ParaViewWeb with its WebGL
renderer ? I know that the technology underneath is slightly different
but I'd be really interested to get some feed back from you about your
experience and especially if your data is precomputed or if they are
generated at runtime ?

If you are interested, you can give a look at some of our "WebGL
static export" done inside a ParaViewWeb sample application here:

Thanks,

Seb
