generate isosurface(s) from volume
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.
