* @brief write binary marching cubes file
|
||
|
|
*
|
||
|
|
* vtkMCubesWriter is a polydata writer that writes binary marching cubes
|
||
|
|
* files. (Marching cubes is an isosurfacing technique that generates many
|
||
|
|
* triangles.) The binary format is supported by W. Lorensen's marching cubes
|
||
|
|
* program (and the vtkSliceCubes object). Each triangle is represented by
|
||
|
|
* three records, with each record consisting of six single precision
|
||
|
|
* floating point numbers representing the a triangle vertex coordinate and
|
||
|
|
* vertex normal.
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* Binary files are written in sun/hp/sgi (i.e., Big Endian) form.
