     a front tracking method based on a marching cubes isosurface extractor, which is related filter generating isosurfaces from a structured point set, is provided to achieve sharp resolution for the simulation of non-diffusive interfacial flow. compared with the traditional topology processing procedure, the current front tracking method is easier to be implemented and presents high performance in terms of computational resources. the numerical tests for 2-d highly-shearing flows and 3-d bubbles merging process are conducted to numerically examine the performance of the current methodology for tracking interfaces between two immiscible fluids. the rayleigh-taylor (rt) and richtmyer-meshkov (rm) instability problems are successfully investigated with the present marching cubes based front tracking method.
