1. A system for generating a curvature adapted isosurface based on Delaunay triangulation comprising: an initial mesh generation module for generating an initial mesh by receiving implicit function data; a curvature geometry module for receiving the initial mesh from the initial mesh generation module, calculating a directional curvature of a curved surface, generating a Delaunay vertex set used for Delaunay triangulation, and recalculating an implicit function; a space division module for generating Delaunay triangulation information by performing Delaunay triangulation based on the generated Delaunay Vertex set from the curvature geometry module; and a final mesh extraction module for receiving the generated Delaunay triangulation information from the space division module and the three dimensional implicit function data updated at the curvature geometry module, and extracting a final mesh the received three dimensional implicit function data.
