【摘要】 科学计算可视化的核心是三维数据场的可视化,当前三维可视化的研究热点是体绘制技术。文中介绍了三维非规则数据场体绘制技术的研究现状。在此基础上,通过对已有非规则数据场体绘制技术和算法的分析比较,预测非规则数据场体绘制技术今后的发展趋势以及将来应该重视的研究方向。除了改进已有算法、将各种算法结合起来外,还应该在硬件及系统加速技术方面做研究,同时结合漫游技术研究和开发高效的三维空间非规则数据场的可视化技术和并行算法。更多还原

【Abstract】 The key of visualization in scientific computing(ViSC) is 3-D visualization. Volume rendering is the hotspot now. Based on the summarizations of the current status about the volume rendering of 3-D irregular data set, this paper analyzes the existed algorithms. It discusses the main direction the volume rendering of 3-D irregular data set develops and some fields we should pay attention to. There is a conclusion that is important to improve old algorithms and to band them together. And the study on hardware and system acceleration technology is important too. Finally, must attach importance to the virtual reality and parallel algorithms.更多还原
