[Paraview] Interfacing to ParaView/VTK

[Berk Geveci]

Hi Hamilton,

I don't think that you can use the ParaView binary distribution for this.
You can't simply load the DLLs and call them. You need some sort of API that
can be accessed through the dynamic API. Python is an obvious choice but can
you call Python from within Matlab?

You may want to take a look at these:
