我无法使用C++中的OpenGL库函数glutSolidSphere()创建一个简单的3D球体.

这是我试过的:

#include<GL/glu.h> 
void display() 
{ 
    glClear(GL_COLOR_BUFFER_BIT); 
    glColor3f(1.0,0.0,0.0); 
    glLoadIdentity(); 
    glutSolidSphere( 5.0, 20.0, 20.0); 
    glFlush(); 
} 

void myInit() 
{
    glClearColor(1.0,1.0,1.0,1.0); 
    glColor3f(1.0,0.0,0.0); 
    glMatrixMode(GL_PROJECTION); 
    glLoadIdentity(); 
    gluOrtho2D(0.0,499.0,0.0,499.0); 
    glMatrixMode(GL_MODELVIEW); 
} 

void main(int argc,char **argv) 
{ 
    qobj = gluNewQuadric(); 
    glutInit(&argc,argv); 
    glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB); 
    glutInitWindowSize(500,500); 
    glutCreateWindow("pendulum");         
    glutDisplayFunc(display); 
    myInit(); 
    glutMainLoop(); 
}
