【摘要】 本文对传统WC算法作了改进,直接根据体元顶点函数值的分布情况,进行等值面的绘制,避免了在预定义的连接方式中查找,提高了算法的效率。同时提出一种基于剖分的方法来消除二义性问题。实验结果表明,本算法大大加速了传统的移动立方体(Marching cubes)算法,显示效果差别不大。更多还原

【Abstract】 An improved algorithm on traditional Marching Cubes is presented in this paper. In this method the isosurface can be protracted based on the function value distributing of the cube vertices directly. The process to look up the configuration style in the predefined table is avoided. The efficiency of the algorithm is enhanced. Meanwhile a dissection method to solve the ambiguity problem is developed. The experiment results show that this algorithm accelerates the speed of Marching Cubes algorithm and the difference of the display performance is little.更多还原
