DiscMc: An Interactive System for Fast Fitting Isosurfaces on Volume Data
This paper describes the architecture of DiscMC, an interactive system which supports isosurfacing on regular volume datasets. DiscMC adopts a discretized fitting algorithm that considerably reduces the number of polygons generated by a Marching Cubes-like scheme while presenting shorter running times. The extracted surfaces are composed of polygons lying within a finite number of incidences, thus allowing simple merging of the output facets into large coplanar triangular facets. A pyramidal representation of the volume dataset has been adopted to speed-up isosurface fitting, by avoiding empty volume traversal, and to support multiple level of resolution fitting. The system has been implemented in a Unix environment, using a de facto standard graphics library. The functionalities and the user interface of the system are described in detail.
