/**
* @class vtkSTLWriter
* @brief write stereo lithography files
*
* vtkSTLWriter writes stereo lithography (.stl) files in either ASCII or
* binary form. Stereo lithography files contain only triangles. Since VTK 8.1,
* this writer converts non-triangle polygons into triangles, so there is no
* longer a need to use vtkTriangleFilter prior to using this writer if the
* input contains polygons with more than three vertices.
*
* @warning
* 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.
