week14

 印出實心圓球

程式碼：

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidSphere(0.3,30,30);///半徑0.3 縱切30 橫片切30

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week14");

    glutDisplayFunc(display);

    glutMainLoop();

}

＋計時器 等四秒背景轉紅

產生切面

void display ()的glutSolidSphere(0.3,30,30); 

改----->glutWireSphere(0.3,30,30);

讓方塊能順時鐘、逆時鐘旋轉

程式碼：

#include <GL/glut.h>

int angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle,0,0,1);

        glutSolidCube(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void timer(int t)

{

    glutTimerFunc(30,timer,t+1);

    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);///定時

    glutMainLoop();

}
