如何删除vtk中的演员?

how to delete an actor in vtk?

例如, 如果我有一个立方体

(这部分代码来自vtk python例子)

import vtk

# create a rendering window and renderer
ren = vtk.vtkRenderer()
renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(ren)

# create a renderwindowinteractor
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)

# create cube
cube = vtk.vtkCubeSource()

# mapper
cubeMapper = vtk.vtkPolyDataMapper()
cubeMapper.SetInput(cube.GetOutput())

# actor
cubeActor = vtk.vtkActor()
cubeActor.SetMapper(cubeMapper)

# assign actor to the renderer
ren.AddActor(cubeActor)

# enable user interface interactor
iren.Initialize()
renWin.Render()
iren.Start()

如何删除这个立方体演员并添加另一个? (这必须按顺序完成)

你试过了吗

ren.RemoveActor(cubeActor);

?

然后,您只需添加另一个演员

ren.AddActor(anotherActor);
