-2 points: There's some speckling on your objects: due to numerical precision, some pixels are being "shadowed" when they shouldn't be.


ID #183 (22/30)
---------------------------------------------
-3 points: Triangles don't draw properly.
-5 points: There's no complex rendered object or even an image of one, and no webpage, so no credit can be given for this section.


ID #329 (23/30)
---------------------------------------------
-2 points: Triangle intersection code isn't quite correct (probably a typo in there somewhere)
-5 points: There is no complex object reading or rendering implemented.


ID #353 (28/30)
---------------------------------------------
-2 points: There's some speckling on your objects: due to numerical precision, some pixels are being "shadowed" when they shouldn't be (or refracted incorrectly).


ID #359(20/30)
---------------------------------------------
-5 points: Refraction has some problems, including some pretty severe speckling problems.
-5 points: There's no complex rendered object or even an image of one, and no webpage, so no credit can be given for this section.

ID #429 (0/30)
---------------------------------------------
-30 points: The program did compile (although you didn't include all the code necessary for it to do so!) but even when I subsituted a working Camera class (which was not included) I didn't get anything approaching a correct result. Given that there was no webpage for this assignment to demonstrate correct functionality, no credit can be given for this assignment.
