有沒有一種方法使用vtk從一個剖切面（可以是傾斜的）的3D坐标和相關資料中獲得2D圖像嗎？在
以下是我讀取結構化網格并設定剖切面的代碼片段：self._reader = vtk.vtkXMLStructuredGridReader()
self._reader.SetFileName(filename)
self._reader.Update()
self._reader.GetOutput().GetPointData().SetActiveScalars("Intensity")
plane = vtk.vtkPlane()
plane.SetOrigin(self._reader.GetOutput().GetCenter())
plane.SetNormal(0, 0, 1)
planeCut = vtk.vtkCutter()
planeCut.SetInput(self._reader.GetOutput())
planeCut.SetCutFunction(plane)
# THIS GIVES THE 3D COORDINATES OF THE POINTS OF THE CUT PLANE
print planeCut.GetOutput().GetPoints()
# THIS GIVES THE DATA ASSOCIATED WITH EACH OF THE POINTS
planeCut.GetOutput().GetPointData().GetAttribute(0)
cutMapper = vtk.vtkPolyDataMapper()
cutMapper.SetInputConnection(planeCut.GetOutputPort())
cutMapper.SetLookupTable(table)
cutMapper.SetScalarRange(0,100)
cutActor = vtk.vtkActor()
cutActor.SetMapper(cutMapper)
self._renderer.AddActor(cutActor)
self._iren.Render()
非常感謝你的幫助
