[vtkusers] Compiling VTK for iOS????

[Joachim Pouderoux]

Sorry there is not suitable example because for now the vtkRenderingVolume
module is not compiled and I could no tell yet if activating it could be
done without any cascading issues... I will try soon and let you know. But
once again, I do not know anything about what you are expecting but
software volume rendering is slow and do not think to get real time
interaction with it on real datasets...

And yes, ParaViewWeb applications works well on iOS browsers!
