Crack-Free Isosurface of Volumetric Scattered Data
Isosurface extraction is the method of visualizing multivariate data in three-dimensional space. It is an important process to observe geometrical distribution of iso-value by isosurface extraction. Data obtained by PIC (Particle In Cell) simulation have a characteristic of irregularly distributed volumetric scattered data. Unlike curved surfaces of implicit function, PIC simulation data cannot be represented by continuous function, and each points have no relationship. In such case, isosurface extraction algorithms do not guarantee crack-free surfaces on their results. This paper describes how we get smooth approximation of volumetric scattered data by using a natural neighbor interpolation, and extract a crack-free isosurface on interpolated data.
