基于纹理的流场动态可视化平台开发
Development of texture-based flow visualization platform
摘要
Abstract
Texture-based flow visualization is a new visualization method of flow field that is based on blending of a warped version of the previous image with a number of background images,a method of high performance using standard features of graphics hardware and no special interpolation.This paper discusses the principles of this new method and develops a visualization platform using Visual C＋ ＋and OpenGL.In the method,several key techniques are adopted,flow field data coordinate conversion,flow field grid modification and drawing background image mapping,generation and integration of noise image,color rendering scalar field,etc.On the platform developed,the river reach between Three Gorges dam and Gezhouba dam is visualized.The platform has advantages of less calculation,more detailed flow field and higher adaptability to data format in comparison to a particles-based system.The platform is useful for dynamic visualization of flow field.关键词
