C++ + glut + OpenGL + gluSphere doesn't draw anything
I'm using GLUT to work with OpenGL (would work with SDL if I could). And I need to draw sphere. I'm using `gluSphere` but it simply doesn't draw anything.<!-- language-all: lang-cpp -->

Here's my GLUT initialization:

    // Initializes display
	glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
	glutInitWindowSize(600, 600);

	// Window settings
	glutCreateWindow("Collision detect");
	glClearColor(0.0, 0.0, 0.0, 1.0);
	glEnable(GL_DEPTH_TEST);
	glDepthFunc(GL_LEQUAL);
	glEnable(GL_TEXTURE_2D);

Quadratic initialization:

    quadratic = gluNewQuadric();
	if( !quadratic){
		throw new PROGRAM_EXCEPTION( "Cannot initialize quadartic", NULL);
	}
	gluQuadricNormals(quadratic, GLU_SMOOTH);
	//gluQuadricDrawStyle( quadratic, GLU_FILL);
	gluQuadricTexture(quadratic, GL_TRUE); // Tried both GL_TRUE and GL_FALSE

And my draw function:

    glPushMatrix();
    glTranslatef( position.getX(), position.getY(), position.getZ());
    // This commented piece of code draws dot where I want it to,
    // so coordinates and camera position are just fine
    //	glBegin(GL_POINTS);
    //	glVertex3f( 0,0,0);
    //	glEnd();
    gluSphere( quadratic, 20.0f, 32, 32); // Tried r = 0.02f, 0.2f, 2.0f, 20.0f, none works
    glPopMatrix();

**Question:** what am I missing? Is there some trick in glut to enable quadratics to draw? Is it incompatible with some of my settings?

*I've spent several hours trying to sort this out, tried different things... If you need some other piece of code, just say which... I don't want to paste 2000 lines here. And one more thing, I've triple check, I'm not using it inside `glBegin()` and `glEnd()`. I have few triangles enclosing the space and they draw just fine.*
