这是一个简易的具有用户交互界面的2D图形绘制系统，系统使用说明请见文件夹中的系统使用说明书（中文），源代码在source文件夹中，项目的设计思路以及核心算法介绍请见项目设计报告（中文）。该项目是学校本专业课程计算机图形学的课程设计。使用愉快！

This is a simple 2D graphics drawing system with GUI. In terms of how to use this system, please check the system manual (written in Chinese). Source code is put in the "source" folder. Please refer to the project design report (written in Chinese) for the designing ideas and instructions for core algorithms. This is the final project for the Computer Graphics course. Have fun!
