Sender: wanmy 02MM frere cadet, message area: ANSI Discuss Title: [Group 3] Chapter 4 Assignment by mnwz Sending site: Sun and Moon Guanghua Wednesday, January 31, 2007 19:16:48, site mail The following text is reproduced from wanmy's mailbox Originally published by mnwz Category A 1. Draw a triangle, a quadrilateral and a polygon with lines 3. Talk about some of the problems you encountered while studying these chapters. Answer: Personally, I think there are two main issues. 1. Not familiar with software or something 2 is the difference between theory and practice. For example, the transparency effect mentioned in the first two lessons, code simplification, and copy-paste issues. Theoretically speaking, it is not very difficult. I can understand all the teacher’s lecture notes, but when I started doing it myself, I discovered that there are various kinds of problems. Such questions I believe that with more practice, things will get better. Category B 1. Use color blocks to draw an arbitrary polygon For this question, I wanted to try to draw the zigzag quadrilateral in the handout, but I didn’t feel good after trying it several times. The main reason is that the small squares in ae are rectangular. The left and right are okay, but the gap between the upper and lower rows is quite large. This creates a feeling that the upper and lower sides are not coherent. I don’t know how the teacher solved this problem @.@ irrigation water Source: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 58.34.17.1] Forward: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 58.34.17.1] Reprint: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 58.24.226.230]
