Question

如何用python使用VTK

Answer 1

新建一个testVTK.py文件：
import vtk

cone_a=vtk.vtkConeSource()

coneMapper = vtk.vtkPolyDataMapper()
coneMapper.SetInputConnection(cone_a.GetOutputPort())

coneActor = vtk.vtkActor()
coneActor.SetMapper(coneMapper)

ren1= vtk.vtkRenderer()
ren1.AddActor( coneActor )
ren1.SetBackground( 0.1, 0.2, 0.4 )

renWin = vtk.vtkRenderWindow()
renWin.AddRenderer( ren1 )
renWin.SetSize( 300, 300 )
renWin.Render()

iren=vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)

iren.Initialize()
iren.Start()
