An accelerated direct rendering algorith of isosurface for 3d data sets is presented. the problem for calculating the intersections of the ray and the bounding cells pierced by the isosurface can be viewed as the problem of sampling alonga 3d discreteray. it is shown that the algorithm is better on memory requirement and speed than traditional algorithm through its realization on pc
提出等值面直接顯示演算法，充分利用數據空間的相關性，把體素分為邊界體素和內部體素，並採用體數據邊界表示法，降低了內存.繪制等值面時，將視線與邊界體素的求交運算轉化為對離散視線上點的掃描，避開對整個體數據空間的遍歷，從而減少了計算量。 -
In the area of isosurface rendering, mc ( marching cubes ) is the classical algorithm
在等值面提取法中最經典的演算法是mc （ marchingcubes ）演算法。 -
Secondly, in this dissertation also introduces a new concept of " connected surface projection region ", and proposes a new algorithm for surface reconstruction based on projection. the zero isosurface is extracted using mt ( marching tetrahedras ) algorithm. in accordance with the intersection feature between isosurface and voxel, this dissertation made improvement in mt algorithm
然後在分析輪廓投影關系特性的基礎上，給出「連接表面投影區域」的概念以及一種基於投影的體數據轉化表面重建方法，選擇marchingtetrahedras （ mt ）演算法進行基於體素的等值面重建，並根據重建的要求對mt演算法進行改進。 -
Mc is a method of accurately defining voxel and isosurface, and becomes a member of pop algorithms of 3d reconstruction now, so it is applied to most merchant software
Mc演算法是一種精確地定義體素及其內等值面的方法，如今已經成為最流行的三維重建演算法之一，在許多商業軟體中也有應用。 -
The visual display of the result data includes structural deforming graph, animation simulation, three dimension image, contour, isosurface and cloud map etc. in this paper, a volume rendering algorithms is discussed
