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.
-
Warning:
-
This filter is specialized to volumes. If you are interested in contouring other types of data, use the general vtkContourFilter. If you want to contour an image (i.e., a volume slice), use vtkMarchingSquares.

Fill a supplied list with contour values. There will be GetNumberOfContours() values in the list. Make sure you allocate enough memory to hold the list.

|
|
|
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.
