《计算机图形学》算法可视化教学研究与实现

Research and realization of algorithm visualization instruction on Computer Graphics

在研究国内外关于可视化理论的基础上,深入探讨了当前引入可视化教学的意义,针对目前计算机图形学教学内容,确定了可视化教学内容及目标,开展了计算机图形学算法可视化教学的研究和实践。利用可视化编程工具VB 6.0对基本图元的生成、多边形填充、直线段裁剪、曲线生成及分形算法进行可视化设计与实现。同时给出了实现过程中发现的问题及解决方法。通过分析,认为采用可视化教学法,对于改变教师的教授方式,帮助学生理解计算机图形学算法有着积极的作用和影响。

Based on the study on the theory of visualization, this paper discusses the significance of visualization instruction. Concerned with the content of computer graphics curriculum, the paper establishes the content and target for visualization instruction and carries out the research and realization on algorithm visualization instruction for computer graphics. This paper carries out visualization design and realization with VB6.0 for computer graphics algorithm. It includes generation of line, circle and curve, polygon filling, line clip and fractals. At the same time the paper gives the problems and solutions in the process of realization. By analysis, the paper believes that adopting the method of visualization instruction will make great help to change the teaching methods and help students understand the algorithm.
