|
|
* @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.
