摘要/Abstract

摘要： 在流场可视化领域,优化算法进行以及提升可视化效果一直是研究者关注的重点。近年来,也有很多评估可视化质量的研究和改进算法被提出,但是,在算法实现和质量评估的过程中往往面临流场方向的二义性以及矢量场方向和大小描述不清的问题。为了解决该问题,尝试将人类视觉感知理论应用于对流场可视化结果质量的评估以及可视化效果的提升上,并在此研究基础上利用模拟旋风数据对二维线积分卷积矢量场可视化算法进行了研究和实现。

Abstract: A great deal of efforts have gone into improving the algorithm and the display of the patterns in field of flow visualization during these years.However,in the process of algorithm implementation and quality assessment,theambiguity of flow field direction and the unclear description of vector field direction and size are often encountered.In order to solve this problem,the theory of human visual perception was used to evaluate the quality of visualization results and improve the patters of flow.To put this design into practice,according to the visual perception,a display using wind vectors with line integral convolution algorithm was presented.

Key words: Flow visualization, LIC, OLIC, Visual perception, Wind field
