计算机图形学——二维卡通人物交互设计

作者：zhu宝宝meng | 来源：互联网 | 2023-09-23 18:55
根据OpenGL提供的直线，多边形绘制算法（橡皮筋效果），实现基于鼠标交互的卡通人物设计与绘制。使用颜色填充与反走样技术对卡

根据OpenGL提供的直线&＃xff0c;多边形绘制算法&＃xff08;橡皮筋效果&＃xff09;&＃xff0c;实现基于鼠标交互的卡通人物设计与绘制。使用颜色填充与反走样技术对卡通人物外貌以及衣着进行绘制。实现对卡通人物轮廓的交互控制&＃xff0c;点击鼠标左键可以对人物五官位置进行拖拽移动调整。按“↑”按键能够实现卡通人物绕坐标原点&＃xff08;或指定点&＃xff09;进行旋转。
附加要求&＃xff1a;选中其中的一个多边形区域&＃xff0c;点击鼠标右键&＃xff0c;弹出一个菜单&＃xff0c;可以对该区域进行不同颜色的选择。可以设计发型、衣服的模版&＃xff0c;当作文件进行存储&＃xff0c;可以在窗口最右边设计一个模板库&＃xff0c;显示保存的发型与衣服&＃xff0c;拖拽到卡通人物上可以为卡通人物进行发型或者衣服的替换。
