文正学院图形学-实验四报告

苏州大学文正学院计算机图形学实验报告实验名称 马的设计 姓名 _许志杰_ 学号 _ 专业班级 _信计_实验日期 _2011_年_12_月_16_日 上课教师 _王平_实验成绩 _一、 实验的目的掌握VC+程序开发环境下，控制台框架下OpenGL基本程序结构；编程实现平面图形的平移、旋转和放缩变换。二、 实验的内容与步骤（可提供屏幕抓图）a. VC+ 6.0控制台程序框架下的OpenGL绘图环境的设置b. VC+ 6.0控制台对于实现马的程序的运行的操作c. 调用实验一中自己中文姓名，从而获取字符的坐标信息，利用这些坐标基于OpenGL中的线段或者多边形绘制自己的姓名于马的下方，并设计上学号。程序设计程序修改程序调试三、 实验结果与分析（可提供屏幕抓图）中文名字的调用上有待提高，试了很多次还是只能放在左脚下，对于马的运行上面的调用还是要细心。其他结果正常，无明显偏差。四、 实验的使用说明和测试的数据无五、 实验中的问题总结与心得体会1、中文名字的调用还不是很熟悉，对于名字位置的导入对于我来说还是有点难度的，还没能掌握；2、在学号的设计上，显得有点繁琐，虽然最后是出来了，但是可以看出写了很多的程序，显得十分累赘；3、调试测试方面有待提高，对于错误的把握方面不能做到一看就知道。六、 源代码清单：#include stdafx.h#include #include #include #include #include #include point.h#include trans.h#define PI 3.14159#define D 4float alpha=0;using namespace std;vector vertices;vectorvector triangles;vector _trans;int v_num,tri_num;void unify_data(void);void read_data(const string &filename);void myinit(void);void normal_key(unsigned char key, int x, int y);void special_key(int key, int x, int y);void reshape(int w, int h);void transformation();void read_data(const string &filename)ifstream fp;fp.open(filename.c_str();POINT tmp;int i0,i1,i2;vector ind;vertices.clear();triangles.clear();int i;fpv_numtri_num;for(i=0;itmp.xtmp.ytmp.z;vertices.push_back(tmp);unify_data();/couttri_numendl;for(i=0;ii0i1i2;ind.push_back(i0);
