from file .ply to stl file

[katia]

Hello! I create a plane with this python code:

sourcer = vtk.vtkPlaneSource()

sourcer.SetXResolution(100);

    sourcer.SetYResolution(100);

    transformr = vtk.vtkTransform()

    transformr.Translate(-30, 0, -100)

    transFr = vtk.vtkTransformPolyDataFilter()

    transFr.SetInputConnection(sourcer.GetOutputPort())

    transFr.SetTransform(transformr)

    w = vtk.vtkPLYWriter()

    w.SetInputConnection(transFr.GetOutputPort())

    w.SetFileName('piano10cm')

    w.SetFileTypeToBinary()

    w.SetDataByteOrderToLittleEndian()

    w.SetColorModeToUniformCellColor()

    w.SetColor(255, 0, 0)

    w.Write()

It is possible to convert this plane in a stl format?

I have tried with:

w = vtk.vtkSTLWriter() instead of w = vtk.vtkPLYWriter()

but the vtk exception is that stl support only triangular mesh and the mesh output is quadratic.

Thanks,

Katia

Dear Katia,

the vtk exception has already solved your issue. 

You need to triangulate the mesh before exporting to STL.

You can learn how to use VTK and VTK filters here:

Best regards
