vtkXMLPolyData Writer/Reader 不可逆
vtkXMLPolyData Writer/Reader not reversible
我有一个 vtkPolyData
对象 c
,我正在尝试使用 vtkXMLPolyDataWriter
:
通过 XML 序列化它
import vtk
print(c.GetNumberOfCells(), c.GetNumberOfPoints())
writer = vtk.vtkXMLPolyDataWriter()
writer.SetInputData(c)
writer.WriteToOutputStringOn()
writer.Update()
s = writer.GetOutputString()
reader = vtk.vtkXMLPolyDataReader()
reader.SetInputString(s)
reader.Update()
c2 = reader.GetOutput()
print(c2.GetNumberOfCells(), c2.GetNumberOfPoints())
打印:
8 6
0 0
有没有办法让这个过程完全可逆?
看来,我在阅读过程中忘记了这行:
reader.ReadFromInputStringOn()
我也把vtkXMLPolyDataReader
改成了vtkPolyDataReader
(和Writer一样)。
