Window aspect ratio and glMatrixMode problem

OpenGL OpenGL: Basic Coding
1

Hello, I have this code:


void Reshape(int width, int height)
{
	glViewport(0, 0, width, height);
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
	glFrustum(-((float) width/ (float) height), ((float) width/ (float) height), -1.0, 1.0, 1.0, 100.0);
}

void Display()
{
	glEnable(GL_LIGHTING);
	glEnable(GL_LIGHT0);

	GLfloat AmbientLight[] = { 0.2, 0.2, 0.2, 1.0 };
	GLfloat DiffuseLight[] = { 0.8, 0.8, 0.8, 1.0 };
	glLightfv(GL_LIGHT0, GL_AMBIENT, AmbientLight);
	glLightfv(GL_LIGHT0, GL_DIFFUSE, DiffuseLight);
	GLfloat LightPosition[] = { 0.0, 1.0, 0.0, 1.0 };
	glLightfv(GL_LIGHT0, GL_POSITION, LightPosition);


	GLfloat Material[] = { 1.0, 0.0, 0.0, 1.0 };
	glMaterialfv(GL_FRONT, GL_AMBIENT, Material);

	glClear(GL_COLOR_BUFFER_BIT);
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
	

	glPushMatrix();
	if (flaga1 != true){
		testWzorX = 0.0;
		testWzorY = 0.4;
	}
	else {
		testWzorX = -1 + (testX / width* 2);
		testWzorY = 1 - (testY / height* 2);
	}
	glTranslatef(testWzorX, testWzorY, -1);
	glutSolidSphere(0.1, 20, 20);
	glPopMatrix();


	glFlush();
	glutSwapBuffers();
}


And this in main:


	glutInit(&argc, argv);
	glutInitWindowSize(width, height);
	glutCreateWindow("OpenGL");


	glutDisplayFunc(Display);
	glutReshapeFunc(Reshape);

I have a problem with this:
-When I move sphere to the corner. It is deformed like this:

EDIT:

It turned out that I was to close to a camera… heh :wink:
