NDLI: An Octree Isosurface Codification Based on Discrete Planes

Content Provider	ACM Digital Library
Author	Boada, Imma Navazo, Isabel
Abstract	Abstract: The purpose of this work is to describe a method to code a decimated model of an isosurface on an octree representation while maintaining volume data if it is needed. The proposed technique is based on grouping the Marching Cubes (MC) patterns in five configurations according the topology and the number of planes of the surface contained into the cell. Moreover, a discrete number of planes, where the surface lain on, is fixed. Starting from a complete volume octree with the isosurface codified at terminal nodes according to the new configurations, a bottom-up strategy is taken in merging cells. Such strategy allows to implicitly represent coplanar faces in upper octree levels without introducing error. At the end of this merging process, when is required, a reconstruction strategy is applied to generate the surface contained in the octree intersected leaves. Some examples with medical data demonstrate that reduction up to 50 percent on the number of polygons could be achieved.
