Hi, everyone,
    I am learning to translate vtk into c++ style, and hit some problems.
    Can someone explain how to translate "eval plane SetOrigin [[pl3d GetOutput] GetCenter]"?
    What does the "eval" mean?
 
piece of the source code:
 
vtkPLOT3DReader pl3d
    pl3d SetXYZFileName "$VTK_DATA/combxyz.bin"
    pl3d SetQFileName "$VTK_DATA/combq.bin"
    pl3d SetScalarFunctionNumber 100
    pl3d SetVectorFunctionNumber 202
    pl3d Update
vtkPlane plane
    eval plane SetOrigin [[pl3d GetOutput] GetCenter]
    plane SetNormal -0.287 0 0.9579
