A new algorithm for multiresolution isosurface extraction

Abstract

We put forward a marching cube algorithm based on the extraction and expression of multiresolution isosurfaces. It can solve the problem of too much and too meticulous triangular meshes on a traditional marching cube algorithm with single resolution. At the same time, under the users' requests, it can apply various precision to different regions of the object to get a compromise between rendering time and image precision. Our algorithm firstly, begins with low resolution images, and gradually extracts high precision isosurfaces from high resolution ones to achieve multiresolution rendering; finally, it establishes the corresponding relationship between different resolution isosurfaces and images. Specifically, the algorithms use a new 3D image encoding method: recursive subdivision wavelet encoding which is more suitable for extracting multiresolution isosurfaces.
