通过研究并行等值面提取与绘制的各项关键技术要点,面向三维标量场的特点,在sort-last并行绘制模式的基础上提出一个三维标量场并行等值面提取与绘制框架.该框架在任务分配时采用静态分配的模式,在等值面提取时采用Marching Tetrahedra等值面提取算法,在并行绘制与场景合成时采用预先构建绘制节点控制模型的混合场景并行绘制合成算法.实验结果表明,该框架能够有效地提高大规模时变三维标量场的等值面提取与绘制效率,满足实际应用的需要.

英文摘要：

By studying the problems of parallel isosurface extraction and rendering,a novel framework is proposed according to the characters of 3D scalar fields.This framework adopts the static task distribution method to keep balance and Marching Tetrahedra algorithm to extract isosurface,and proposes a mixed parallel rendering and combining method based on rendering node control model,which is prearranged for parallel rendering and scene integration.An effective improvement on the capability of parallel isosurface extraction and rendering of large-scale 3D scalar fields is given by the experiments.
