Error Evaluation of Isosurface from Volume Data Sampled on Face-Centered Cubic Lattice

Abstract

In this report, We evaluated errors of isosurfaces from volume data sampled on face-centered cubic(FCC) lattice. We had previously developed a method for FCC based isosurface generation and modified it. To evaluate the error, we generated isosurfaces using the FCC method and the Modified FCC(MFCC) method and commonly used Marching Cubes(MC) method from the same volume data algebraically defined, then we compared the errors from a true surface among the three methods. We also tried to apply the FCC methods to a medical CT data. As a result, It was shown that the MFCC method made the root-mean-square(RMS) error smaller than that obtained when the MC method was used.
