摘要

Volume drawing technology was usually used for the visualization of riddled volume data. The size of the body unit would be varied, if the hierarchy octree structure was used, It got the balance between the number of body unit and the expressed three-dimensional volume accuracy. In this letter, we firstly construct the octree for riddled volume data set and implement the algorithm from riddled nodes to B-spline surface by the least square method. Then we got the cutted-polygon by using the cutting-point between B-spline surface and octree,.At the same time curved-surface reconstruction is achieved rapidly through the rule of optimal triangle-parted.
