- Our scene was constructed from 2 spheres and a background box.

- We used texture mapping for all the pieces.

- We used one directional light source, that’s shining in the direction of (0.6, 0, 0.5)

- Since our background image (stars) was made of bunch of dots, we would lose a lot of stars if 
  we would render the scene with Antialiasing enabled. Of course that was due to the averaging 
  part of our algorithm. Therefore we decided not to use Antialiasing.
