摘要
平面矢量场可视化是科学计算可视化的重要研究内容。矢量场以直观的图形图像显示场的运动,透过抽象数据有效洞察其内涵本质和变化规律,广泛应用于计算流体力学、航空动力学、大气物理和气象分析等领域。对平面矢量场进行可视化的方法有很多种,常见的有点图标法、流线法、线积分卷积法和拓扑分析法等。论文主要研究常见的可视化方法,分析它们的性能,并通过实际的例子,对具体的可视化结果图像进行比较。通过该研究,能够给人们在选择可视化方法时提供依据。
The planar vector field visualization is an important part of visualization in scientific computing.Vector field can display field with an intuitive graphical image,at the same time,it can validly insight into the nature and variation through the abstract data,and it has been used widely in computational fluid dynamics,air dynamics,atmospheric physics and meteorology analysis,etc. The methods of the planar vector field visualization have many,including point icon method,streamline method,line integral convolution and topology analysis method,etc.In this paper,common used visualization methods are introduced,and the properties are analyzed,furthermore,the visualization images are compared through practical examples.Through this study,hope to provide a basis for people in choosing the visualization methods.
