用程式畫圓球

#include <GL/glut.h>

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glColor3f(1,1,0);

    glutSolidSphere(0.5,30,30);

    glutSwapBuffers();

}

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

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("Week03-circle");

    glutDisplayFunc(display);

    glutMainLoop();

}
