// .NAME vtkSTLReader - read ASCII or binary stereo lithography files
|
|
// .SECTION Description
|
|
// vtkSTLReader is a source object that reads ASCII or binary stereo
|
|
// lithography files (.stl files). The FileName must be specified to
|
|
// vtkSTLReader. The object automatically detects whether the file is
|
|
// ASCII or binary.
|
|
//
|
|
// .stl files are quite inefficient since they duplicate vertex
|
|
// definitions. By setting the Merging boolean you can control whether the
|
|
// point data is merged after reading. Merging is performed by default,
|
|
// however, merging requires a large amount of temporary storage since a
|
|
// 3D hash table must be constructed.
|
|
|
|
// .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.
