Detailed Description

sample an implicit function over an hyperoctree

vtkHyperOctreeSampleFunction is a source object that evaluates an implicit function to drive the subdivision process. The user can specify the threshold over which a subdivision occurs, the maximum and minimum level of subdivisions and the dimension of the hyperoctree.

Reimplemented from vtkHyperOctreeAlgorithm.

virtual int vtkHyperOctreeSampleFunction::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkHyperOctreeAlgorithm.
