THE ROTATING CUBE

It's time for some "real" 3D!
Now that you know how to translate, rotate you can create the famous spinning cube.. We do this by drawing 6 quads in the shape of a cube.. We can give each quad a different color to make it a bit cooler looking..

int DrawGLScene(GLvoid)		// Here's Where We Do All The Drawing
{
    // Clear Screen And Depth Buffer
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    // Reset The Current Modelview Matrix
    glLoadIdentity();

//NEW//////////////////NEW//////////////////NEW//////////////////NEW/////////////

  glTranslatef(0.0f, 0.0f,-7.0f);	// Translate Into The Screen 7.0 Units
  glRotatef(rotqube,0.0f,1.0f,0.0f);	// Rotate The cube around the Y axis
  glRotatef(rotqube,1.0f,1.0f,1.0f);
  glBegin(GL_QUADS);		// Draw The Cube Using quads
    glColor3f(0.0f,1.0f,0.0f);	// Color Blue
    glVertex3f( 1.0f, 1.0f,-1.0f);	// Top Right Of The Quad (Top)
    glVertex3f(-1.0f, 1.0f,-1.0f);	// Top Left Of The Quad (Top)
    glVertex3f(-1.0f, 1.0f, 1.0f);	// Bottom Left Of The Quad (Top)
    glVertex3f( 1.0f, 1.0f, 1.0f);	// Bottom Right Of The Quad (Top)
    glColor3f(1.0f,0.5f,0.0f);	// Color Orange
    glVertex3f( 1.0f,-1.0f, 1.0f);	// Top Right Of The Quad (Bottom)
    glVertex3f(-1.0f,-1.0f, 1.0f);	// Top Left Of The Quad (Bottom)
    glVertex3f(-1.0f,-1.0f,-1.0f);	// Bottom Left Of The Quad (Bottom)
    glVertex3f( 1.0f,-1.0f,-1.0f);	// Bottom Right Of The Quad (Bottom)
    glColor3f(1.0f,0.0f,0.0f);	// Color Red	
    glVertex3f( 1.0f, 1.0f, 1.0f);	// Top Right Of The Quad (Front)
    glVertex3f(-1.0f, 1.0f, 1.0f);	// Top Left Of The Quad (Front)
    glVertex3f(-1.0f,-1.0f, 1.0f);	// Bottom Left Of The Quad (Front)
    glVertex3f( 1.0f,-1.0f, 1.0f);	// Bottom Right Of The Quad (Front)
    glColor3f(1.0f,1.0f,0.0f);	// Color Yellow
    glVertex3f( 1.0f,-1.0f,-1.0f);	// Top Right Of The Quad (Back)
    glVertex3f(-1.0f,-1.0f,-1.0f);	// Top Left Of The Quad (Back)
    glVertex3f(-1.0f, 1.0f,-1.0f);	// Bottom Left Of The Quad (Back)
    glVertex3f( 1.0f, 1.0f,-1.0f);	// Bottom Right Of The Quad (Back)
    glColor3f(0.0f,0.0f,1.0f);	// Color Blue
    glVertex3f(-1.0f, 1.0f, 1.0f);	// Top Right Of The Quad (Left)
    glVertex3f(-1.0f, 1.0f,-1.0f);	// Top Left Of The Quad (Left)
    glVertex3f(-1.0f,-1.0f,-1.0f);	// Bottom Left Of The Quad (Left)
    glVertex3f(-1.0f,-1.0f, 1.0f);	// Bottom Right Of The Quad (Left)
    glColor3f(1.0f,0.0f,1.0f);	// Color Violet
    glVertex3f( 1.0f, 1.0f,-1.0f);	// Top Right Of The Quad (Right)
    glVertex3f( 1.0f, 1.0f, 1.0f);	// Top Left Of The Quad (Right)
    glVertex3f( 1.0f,-1.0f, 1.0f);	// Bottom Left Of The Quad (Right)
    glVertex3f( 1.0f,-1.0f,-1.0f);	// Bottom Right Of The Quad (Right)
  glEnd();			// End Drawing The Cube

  rotqube +=0.9f;			// Increase Angle

//NEW//////////////////NEW//////////////////NEW//////////////////NEW/////////////

    return TRUE;			// Keep Going
}

Try setting up the cube by yourself with GL_QUADS but also by using GL_TRIANGLES. It will take a while but you will get there.. And when you do you have lerned a lot about drawing in 3D :) When you know how to draw a cube manually you can always move on to loading geometry from a file..
