[vtkusers] Filling contour with edge visibility on

[Jothy]

Here is it!

*# A simple script to demonstrate the vtkCutter function
import vtk


#Create a cube
cube=vtk.vtkSphereSource()
cube.SetRadius(50)
cube.SetThetaResolution(200)
cube.SetPhiResolution(200)
cubeMapper=vtk.vtkPolyDataMapper()
cubeMapper.SetInputConnection(cube.GetOutputPort())

#create a plane to cut,here it cuts in the XZ direction (xz
normal=(1,0,0);XY =(0,0,1),YZ =(0,1,0)
plane=vtk.vtkPlane()
plane.SetOrigin(10,0,0)
plane.SetNormal(1,0,0)

#create cutter
cutter=vtk.vtkCutter()
cutter.SetCutFunction(plane)
cutter.SetInput(cubeMapper.GetInput())
cutter.Update()

FeatureEdges=vtk.vtkFeatureEdges()
FeatureEdges.SetInputConnection(cutter.GetOutputPort())
FeatureEdges.BoundaryEdgesOn()
FeatureEdges.FeatureEdgesOff()
FeatureEdges.NonManifoldEdgesOff()
FeatureEdges.ManifoldEdgesOff()
FeatureEdges.Update()




cutMapper=vtk.vtkPolyDataMapper()
cutMapper.SetInput(FeatureEdges.GetOutput())
cutActor=vtk.vtkActor()
cutActor.GetProperty().SetColor(1,1,0)
cutActor.GetProperty().SetEdgeColor(1,0.5,0)
cutActor.GetProperty().SetLineWidth(2)
cutActor.GetProperty().EdgeVisibilityOn()
cutActor.GetProperty().SetOpacity(0.7)
cutActor.SetMapper(cutMapper)


#create renderers and add actors of plane and cube
ren = vtk.vtkRenderer()
ren.AddActor(cutActor)


#Add renderer to renderwindow and render
renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(ren)
renWin.SetSize(600, 600)
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)
ren.SetBackground(0,0,0)
renWin.Render()*
