#include <vtkMarchingCubes.h>
vtkMarchingCubes is a filter that takes as input a volume (e.g., 3D structured point set) and generates on output one or more isosurfaces. One or more contour values must be specified to generate the isosurfaces. Alternatively, you can specify a min/max scalar range and the number of contours to generate a series of evenly spaced contour values.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

void vtkMarchingCubes::SetValue | ( | int | i, | |
double | value | |||

Set a particular contour value at contour number i. The index i ranges between 0<=i<NumberOfContours.

void vtkMarchingCubes::SetNumberOfContours | ( | int | number | ) | [inline] |
Set the number of contours to place into the list. You only really need to use this method to reduce list size. The method SetValue() will automatically increase list size as needed.

virtual void vtkMarchingCubes::SetComputeNormals | ( | int | ) | [virtual] |
