Hints for CS543 Project 4 Try to create an object (or set of objects) that isn't too trivial. Many students in the past have just used a couple cubes, which is kind of boring and often doesn't test the hidden surface removal algorithm very well. Try to use a couple of the primitives we discussed in class (e.g., cylinders, prisms, wedges) to make something a bit more interesting. Make sure that from at least one view at least one surface is partially (not totally) blocked from view.
