[Paraview] Plugin for rendering vtkGraph in ParaView

[Biddiscombe, John A.]

Sebastien

There used to be an infoviz plugin for paraview (I think). Is this what’s left of it or a different integration you’ve done separately?

Here it is...
But remember, this is just a quick integration that need more works to properly go into ParaView.

Hi, Seb

It's very kind of you to share the code, which will make me understand Paraview much better.

There is little information about cusomizing Paraview, so a workable example will be very useful.

Thanks again.

Hi,

We are currently working in bringing that VTK renderer + representation into ParaView. Although, that work won't be available inside ParaView soon as more effort need to be done toward a proper integration.
Although, if you are willing to go further on that matter, I can share that piece of code that allow rendering within the python context of ParaView.

Hi, all.

I hope to render vtkGraph in ParaView, which is available in VTK. The related classes are vtkGraphLayoutView, vtkRenderedGraphRepresentation. There is also a source class: vtkRandomGraphSource.

My plan is to realize a customized view for vtkGraph. As an experiment, there are at least 3 things to to:
1. a source for vtkGraph, which is the easiest part. Just load a xml file wrapping vtkRandomGraphSource.
2. a view. May be a subclass of vtkPVRenderView, with its RenderView replaced by vtkGraphLayoutView. I have tried that, and the view shows in MainWindow, but I don't know if it really works.
3. a representation. vtkGraphLayoutView uses vtkRenderedGraphRepresentation by default. But I don't know how to use this representation class in ParaView, only find that every representation class in  Paraview is derived from vtkPVDataRepresentation.

I am trying to write a custumized grapg view according to my plan. Before everything is done, I have to figure out how view and representaion work in Paraview.

My questions are:
1. Does my plan works? Is there any aspect I have ignored?
2. How to use a vtk representation class in Paraview?
3. What is the best way to visualize graph in Paraview?

Any advices will be appreciated!
