[Paraview] VTK embedded models in JSP

[Sebastien Jourdain]

Hi Daniel,

I thought that VTK would contain the WebGL exporter which it doesn't (for
now). So you are stuck with pvpython for now.

Here is a pvpython script

>>> from paraview.simple import *

>>> from paraview.vtk import *

>>> from vtkPVClientServerCoreRenderingPython import *

>>> from vtkPVVTKExtensionsWebGLExporterPython import *


>>> Cone()
>>> Show()
>>> view = Render().GetClientSideObject()

>>> exporter = vtkPVWebGLExporter()

>>> exporter.SetFileName("/tmp/index.html")

>>> exporter.SetRenderWindow(view.GetRenderWindow())

>>> exporter.Update()
