/**
* @class vtkMCubesWriter
* @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.
