[vtkusers] stl mesh problems

[stefano scarparo alves]

Hi, I'm writing a program to convert a CT DICOM file into an STL file
suitable for stereolitography but allways have problems with generated mesh;
probably first and last slice remain open and not closed as it should be for
stereolitography. Has anybody an idea? Thanks in advance.

Here is a peace of tcl code as example:

package require vtk
package require vtkinteraction
package require vtktesting

vtkPolyDataReader pdreader
    pdreader SetFileName "inputfile.vtk"

vtkTriangleFilter tf
    tf SetInput [pdreader GetOutput]

vtkPolyDataNormals normals
    normals SetInput [tf GetOutput]

vtkSTLWriter stlBinary
stlBinary SetInputConnection [tf GetOutputPort]
stlBinary SetFileName "outfile.stl"
stlBinary SetFileType 2
stlBinary Write
