【摘要】 体绘制技术是科学计算可视化的重要组成部分,具有较大的研究价值和广阔的应用前景。体绘制有两种方法即间接体绘制和直接体绘制,直接体绘制(简称体绘制)以其在体数据处理及特征信息表现方面的优势,已经得到了研究者越来越多的重视。文章对四种典型的体绘制算法进行了描述,并概述了它们的改进之处,同时对它们各自的性能进行了分析和评价。更多还原

【Abstract】 Volume rendering technique is one of important parts for ViSCC(Visualization in Scientific Computing).There are two classes:indirect volume rendering and direct volume rendering(simply called volume rendering).This paper dis-cusses four widely-used volume rendering algorithms :raycasting,splatting,shear-warp and hardware-assisted3D texture-mapping and gives a summarized description to improvements to each algorithm.In the end,it compares the pros and cons of these algorithms in order to promote further research of volume rendering algorithms.更多还原
