#include <CGAL/Isosurfacing_3/edge_intersection_oracles_3.h>

Definition

The class Linear_interpolation_edge_intersection uses linear interpolation to find the intersection point between an edge and the isosurface.

This class is for example suitable when interpolated discrete values are being used.
