摘要
在深入研究计算机图形学三维变换算法原理的基础上,分析了算法可视化的实质,建立了三维坐标系,并实现了坐标的投影变换,运用动态演示的方法,结合交互控制技术,实现了三维变换算法可视化教学演示系统CAI。学习者可以更快、更准确地理解计算机图形学三维变换的算法实质,有效地提高了教学质量。
On the basis of researching the arithmetic theory of three-dimensional transform in computer graphics, analyzing the essentials of the arithmetic visualization, creating the 3-D coordinate systems, the 3-D coordinate projection transform is realized. With the dynamic display and interactive function, a computer-aided instruction system (CAI) for arithmetic visualization is carried out. By using this CAI the students can better understand the arithmetic theory quickly, and the teaching quality also can be improved effectively.
