摘要
提出了基于min-max Octree快速分类Shear-warp的交互式海量数据场体绘制算法。主要包括根据海量数据的特征,快速读入数据以及设计适当的不透明度传递函数;建立Summed-Area表与min-max Octree数据结构,并对体数据进行快速分类,然后,利用分类的结果进行快速体绘制。实验证明该方法不仅效率高,而且显示效果好。
An interactive volume rendering method formass date sets based on shear-warp algorithm after fast classification with min-max Octree is proposed in this paper. First, themass data sets are inputted fast. Then, the better opacity transfer function is presented. Finally, the shear-warp algorithm after fast classification with min-max Octree is used to render the volume fast. Experiments demonstrate the good performance of the proposed method.
