OpenGL大作业 三维小破房设计(附报告)
资源内容介绍
大一刚上完程序设计基础课的大作业，要求用到图形库，懵逼的我 临时参考网上的程序初步了解了一下。https://blog.csdn.net/GUOXIAOHE0000/article/details/80893549在上链接的代码中进行了修改，删去了一些东西。增加了房屋外部结构、内部家具、草地、树木，月亮和字母。另外增加了方向键等按键调整视角包括源代码以及实验报告仅用于学习及应付作业希望可以帮助你 #include<windows.h>#include<gl/glut.h>#include<stdio.h>#include<math.h>GLuint drawcube,drawsphere,drawteapot;static float a=0.0;static GLdouble eye=1.0;static GLfloat locate=1.0;static int lflag=GL_TRUE,rflag=GL_TRUE;void reshape(int w, int h){ glViewport(0,0,(GLsizei)w,(GLsizei)h);
