* @class vtkSliceCubes
|
|
* @brief generate isosurface(s) from volume four slices at a time
|
|
*
|
|
* vtkSliceCubes is a special version of the marching cubes filter. Instead
|
|
* of ingesting an entire volume at once it processes only four slices at
|
|
* a time. This way, it can generate isosurfaces from huge volumes. Also, the
|
|
* output of this object is written to a marching cubes triangle file. That
|
|
* way, output triangles do not need to be held in memory.
|
|
*
|
|
* To use vtkSliceCubes you must specify an instance of vtkVolumeReader to
|
|
* read the data. Set this object up with the proper file prefix, image range,
|
|
* data origin, data dimensions, header size, data mask, and swap bytes flag.
|
|
* The vtkSliceCubes object will then take over and read slices as necessary.
|
|
* You also will need to specify the name of an output marching cubes triangle
|
|
* file.
|
|
*
|
|
* @warning
|
|
* This process object is both a source and mapper (i.e., it reads and writes
|
|
* data to a file). This is different than the other marching cubes objects
|
|
* (and most process objects in the system). It's specialized to handle very
|
|
* large data.
|
|
*
|
|
* @warning
|
|
* This object only extracts a single isosurface. This compares with the other
|
|
* contouring objects in vtk that generate multiple surfaces.
|
|
*
|
|
* @warning
|
|
* To read the output file use vtkMCubesReader.
