摘要： 针对科学计算产生的矢量场数据可视化需求,利用OpenGL图形库和MFC技术实现了基于几何图形的矢量场可视化技术.在对规则网格和非规则网格单元数据的预处理之后,以彩色箭标及流线的形式表现矢量场的结构和特征等信息.此外,通过对显示图形的变换和渲染等交互操作,获得矢量场不同角度的细节信息.采用C++开发了一套矢量场可视化应用程序.通过与Tecplot软件进行对比分析,表明本系统具有良好的矢量场可视化效果.

关键词: 矢量场, 可视化, OpenGL, 箭标, 流线

Abstract: Given the need for scientific computing visualization of vector field data, the OpenGL library and MFC technology were used to achieve vector field visualization based on geometry graphics. After pre-processing regular and non-regular mesh data, the structures and features of the vector field were exhibited by colored arrows and streamlines. In addition, details of the vector field were acquired through interactive operations such as transformation and graphic rendering. A set of application programs for vector field visualization was developed. By comparing with Tecplot, the system has better effectivity of vector field visualization.
