Detailed Description
generate isosurface(s) from a Volume using the Marching Cells algorithm
Takes as input a volume (e.g., 3D structured point set) and generates on output one or more isosurfaces. Multiple contour values must be specified to generate the isosurfaces.
This implementation is not optimized for all use cases, it is used by the more general Contour filter which selects the best implementation for all types of DataSet . .
