Abstract - Based on the summary of the teaching experience on
“Computer Graphics”, this paper discusses the significance of
visualization instruction and carries out the design and
realization on visualization instruction of computer graphics
algorithm. It includes generation of basic primitives, geometric
transformations of these geometric objects, area filling, line
clip and so on. At the same time the paper gives the problems
and solutions that in the process of realization. By analysis, the
paper believes that adopting the method of visualization
instruction will greatly improve teaching effect and help
students more deeply understand the algorithm.
