我必须将照明放在OpenGL图片中,但我不知道如何放置正确的点光照明,如下图所示:

现在我尝试了不同的照明模式,但结果如下:(

我附上了我用于结果的代码.怎么了？

    float specref[] = { 1.0f, 1.0f, 1.0f, 1.0f };
    // Light values and coordinates
    float ambientLight[] = { 0.3f, 0.3f, 0.3f, 1.0f };
    float diffuseLight[] = { 0.7f, 0.7f, 0.7f, 1.0f };
    float specular[] = { 1.0f, 1.0f, 1.0f, 1.0f};
    float lightPos[] = { 0.0f, -150.0f, -150.0f, 1.0f };

    glEnable ( GL_LIGHTING ) ;

    glLightfv(GL_LIGHT0,GL_AMBIENT, ambientLight);
    glLightfv(GL_LIGHT0,GL_DIFFUSE,diffuseLight);
    glLightfv(GL_LIGHT0,GL_SPECULAR,specular);
    glLightfv(GL_LIGHT0,GL_POSITION,lightPos);
    glEnable(GL_LIGHT0);
    glColorMaterial(GL_FRONT, GL_AMBIENT_AND_DIFFUSE);
    glMaterialfv(GL_FRONT_AND_BACK, GL_SPECULAR,specref);
    glMateriali(GL_FRONT_AND_BACK,GL_SHININESS,128);
    glEnable ( GL_COLOR_MATERIAL ) ;

    glClearColor (1.0, 1.0, 1.0, 1.0);
    glColor3f(0.0,0.0,0.0);
