Hi Seb,
There is really not much in my pipeline at the
moment. I will do offline rendering using vtk,
save the vtp file, and load it on paraviewweb.
At the moment I play with sphere and cone
objects.
I uploaded the application here with the state files
http://vision.lbl.gov/People/bilgin/PWShuttle.tar.gz
Thank you,
Cagatay
