// .NAME vtkSTLWriter - write stereo lithography files
// .SECTION Description
// vtkSTLWriter writes stereo lithography (.stl) files in either ASCII or
// binary form. Stereo lithography files only contain triangles. If polygons
// with more than 3 vertices are present, only the first 3 vertices are
// written. Use vtkTriangleFilter to convert polygons to triangles.
// .SECTION Caveats
// Binary files written on one system may not be readable on other systems.
// vtkSTLWriter uses VAX or PC byte ordering and swaps bytes on other systems.
