先將git指令下載 把專案clone下來
下載葉老師上課用軟體freeglut壓縮 / 將裡面的freeglut檔案複製到桌面
/ 再將裡頭lib的libfreeglut.a複製並貼上 / 將複製的改檔名為libglut32.a
開啟codeblocks / 新增 glut專案 / 取名為 week14-1_timer
第一個程式
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glRotatef(angle,0,0,1);
glutSolidTeapot(0.3);
glPopMatrix();
glutSwapBuffers();
}
void timer(int t)
{
glutTimerFunc(500,timer,t+1);///設定下個鬧鐘
angle+=90;///+90度
glutPostRedisplay();///重新畫畫面
}
int main(int argc,char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14");
glutDisplayFunc(display);
glutTimerFunc(2000,timer,0);///設定timer格式
glutMainLoop();
}
新增 glut專案 / 取名為 week14-2_timer_play
第二個程式(可90度90度旋轉茶壺)
///week14-2_timer_play
#include <GL/glut.h>
float angle=0;
void display()
{
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

glutTimerFunc(0,timer,0);
}
int main(int argc,char** argv)

glutCreateWindow("week14");
glutDisplayFunc(display);
glutKeyboardFunc(keyboard);///用keyboard()
///glutTimerFunc(2000,timer,0);///設定timer格式
glutMainLoop();
}
按下空白鍵的話 會開始旋轉90度
再多按一下空白鍵的話 茶壺會旋轉更快
開啟excel檔 / 撰寫以下數值
