This is a development idea for discussion and experimentation at the May, 2010 Hackfest

1. Possible vtkXIPActor (or vtkOpenInventorActor) 1. Proof of Concept
   • A link between vtk and xip could be done by following the example of the vtkOpenGLScriptedActor. In this example: ** vtk sets up the rendering context as it normally does during a call to the Render() method on a vtkOpenGLRenderWindow ** the actor’s Render() method is responsible for calling the OpenGL API (in this case using PyOpenGL.
   • It should be possible to encapsulate OpenInventor scene graphs inside a similar structure.

1. Open issues - Mapping vtk events into OpenInventor events so that it is possible to interact with the XIP scene - Mapping xip inputs (like volume data) generically to a "Set*" methods on the vtk object.

1. Possible Usage  vtkXIPActor *xipActor = vtkXIPActor::New();  xipActor-SetSceneGraph("XIPSampleScene.iv");  renderer-AddActor(xipActor);  renderWindow-Render();
