CS3388 ASSIGNMENT 3
Weight: 10% of final mark
The purpose of this assignment is to complete a 3D graphics program capable of
displaying parametric objects as polygonal surfaces. For this purpose, you are required
Complete the methods in class lightSource. The methods needing completion are the
setter and getter methods.
Complete the constructor and the helper methods in class tessel. This class tessels
the objects of the graphical scence into convex polygons, and computes the color
shade to fill the polygons with. In order to program this properly, refer to the notes
on lighting models (particularly the Section on A Practical Lighting Model), and
the comments included with the provided code tessel.py
If you are starting the assignment before Sunday Feb. 16th at 11:00pm, you will
have to rely on the classes that you have programmed for assignment 2 until its
solution becomes available, which is shortly after its late deadline. It is advised that
you use the solution code of assignment 2 when it comes available.
