[python][VTK]vtk安装后测试代码

测试vtk版本为9.2.5

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(1.0, 1.0, 1.0)  
 ren1.SetBackground2(0.1, 0.2, 0.4)
 ren1.SetGradientBackground(1)renWin = vtk.vtkRenderWindow()
 renWin.AddRenderer(ren1)
 renWin.SetSize(300, 300)
 renWin.Render()iren = vtk.vtkRenderWindowInteractor()
 iren.SetRenderWindow(renWin)iren.Initialize()
 iren.Start()

运行结果：
