✨Timer設置
🔼畫出圓球
🧷程式
#include <GL/glut.h>
void display()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glutSolidSphere(0.3,30,30);//實心的圓球 半徑 縱切 橫切
///glutWireSphere(0.3,30,30); 圓的線條 半徑 縱切 橫切
glutSwapBuffers();
}
int main(int argc,char ** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14 timer");
glutDisplayFunc(display);
glutMainLoop();
}

🔼計時器&改顏色
🧷程式
#include <GL/glut.h>
void display()
{

glutSolidSphere(0.3,30,30);
glutSwapBuffers();
}
void timer(int t)
{
glClearColor(1,0,0,0);///背景設為紅色
}
int main(int argc,char ** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14 timer");
glutDisplayFunc(display);
glutTimerFunc(4000,timer,0);///等待時間 執行誰 參數
glutMainLoop();
}

🔼計時旋轉方塊
🧷程式

glPopMatrix();///方塊旋轉
glutSwapBuffers();
}
void timer(int t)
{
glutTimerFunc(30,timer,t+1);///設定下一個timer 下次計時的時間
angle++;
display();
}
int main(int argc,char ** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week14 timer");
glutDisplayFunc(display);
glutTimerFunc(4000,timer,0);///第一個計時器
glutMainLoop();
