[vtkusers] Exporting to STL

[Stewart Dickson]

The STL file format requires that the cone's cap be composed strictly of 
a triangular mesh -- not an n-gon approximating a circle.   
http://www.ennex.com/~fabbers/StL.asp     You need an algorithm to 
generate a triangular mesh which fills-in the circular base of the 
cone.   vtkTriangleFilte 
<http://www.vtk.org/doc/nightly/html/classvtkTriangleFilter.html>r()?

Here's a pipeline I use to successfully generate STL files from the 
vtkContourFilter():

vtkImageReader 
<http://www.vtk.org/doc/nightly/html/classvtkImageReader.html> [raw 
UnsignedChar; DataSpacing 0.00585938 -- Data size: 52,428,800 BYTES] -> 
vtkContourFilter 
<http://www.vtk.org/doc/nightly/html/classvtkContourFilter.html> [Value 
0 16; ComputeScalarsOn] -> vtkCleanPolyData 
<http://www.vtk.org/doc/nightly/html/classvtkCleanPolyData.html> -> 
vtkTriangleFilter 
<http://www.vtk.org/doc/nightly/html/classvtkTriangleFilter.html> -> 
vtkSTLWriter 
<http://www.vtk.org/doc/nightly/html/classvtkSTLWriter.html> [FileType 
2/Binary]
