[Paraview-developers] How to add multiple inputs to a plugin (writer)

[Cory Quammen]

Yes, look at File -> Export Scene.

You can export to WebGL, VRML, X3D, etc. One of these options should be a
good example for you to follow. The XML for the WebGL exporter proxy is in

ParaView/ParaViewCore/ServerManager/SMApplication/Resources/utilities.xml

and the exporter proxy is described here:
