GUI for surfaceFeatureExtract
5 Attachment(s)
Hi,
I am experimenting with a GUI (pyvtk) to get a feeling which "-includedAngle" would make sense.
PHP Code:
#!/usr/bin/env python
import vtk
def callback(obj, event):
global featureedges
sliValue = obj.GetValue()
featureedges.SetFeatureAngle(mathslider.Round(sliValue))
reader = vtk.vtkOBJReader()
#reader.SetFileName("/home/opencfd/pyscript/propellerTip.obj")
reader.SetFileName("/home/opencfd/pyscript/motorBike.obj")
#reader = vtk.vtkSTLReader()
#reader.SetFileName("/home/opencfd/pyscript/bullet.stl")
reader.Update()
mapper1 = vtk.vtkPolyDataMapper()
mapper1.SetInputConnection(reader.GetOutputPort())#just visualizing without FeatureEdges stuff
actor1 = vtk.vtkActor()
actor1.SetMapper(mapper1)
actor1.GetProperty().SetOpacity(0.1)# better slider
featureedges = vtk.vtkFeatureEdges()
featureedges.SetInputConnection(reader.GetOutputPort())
#featureedges.SetFeatureAngle(130) ###slider (default is 30)
featureedges.BoundaryEdgesOff()
featureedges.ManifoldEdgesOff()
featureedges.NonManifoldEdgesOff()
mapper = vtk.vtkPolyDataMapper()
mapper.SetInputConnection(featureedges.GetOutputPort())
actor = vtk.vtkActor()
actor.SetMapper(mapper)
ren = vtk.vtkRenderer()
renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(ren)
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)
mathslider = vtk.vtkMath()#mathslider.Round(sliderRep.GetValue())
#sliderRep
sliderRep = vtk.vtkSliderRepresentation2D()
sliderRep.SetTitleText("FeatureAngle")
sliderRep.GetTitleProperty().SetColor(0,1,0)
sliderRep.GetTitleProperty().ShadowOff()
sliderRep.GetSliderProperty().SetColor(0,0,1)
sliderRep.GetTubeProperty().SetColor(1,0,0)
sliderRep.GetCapProperty().SetColor(1,1,.5)
sliderRep.GetPoint1Coordinate().SetCoordinateSystemToNormalizedDisplay()
sliderRep.GetPoint1Coordinate().SetValue(0.2, 0.1)
sliderRep.GetPoint2Coordinate().SetCoordinateSystemToNormalizedDisplay()
sliderRep.GetPoint2Coordinate().SetValue(0.8, 0.1)
sliderRep.SetLabelFormat("%4.0lf")
#sliderRep.SetMinimumValue(0.5)
sliderRep.SetMaximumValue(180)#155
sliderRep.SetValue(1)
#sliderWidget
sliderWidget = vtk.vtkCenteredSliderWidget()
#sliderWidget = vtk.vtkSliderWidget()
sliderWidget.SetInteractor(iren)
sliderWidget.SetRepresentation(sliderRep) #passt
#sliderWidget.KeyPressActivationOff() #
#sliderWidget.SetAnimationModeToAnimate()#ob das gut ist
sliderWidget.AddObserver("InteractionEvent", callback)
#sliderWidget.On()
#featureedges.SetFeatureAngle(sliderRep.GetValue())#mathslider.Round(sliderRep.GetValue())
ren.AddActor(actor)
ren.AddActor(actor1)
ren.SetBackground(.2, .2, .2)
renWin.SetSize(500, 500)
iren.Initialize()
renWin.Render()
sliderWidget.On()
iren.Start()
you need "python-vtk" to get it run, hope someone finds it useful! I hoped "vtkSliderWidget()" would work for the script, unfortunatly only "vtkCenteredSliderWidget()" works partually |
