---------------------------------------------
-1 point: There was only one additional scene - the assignment required two. Also, there was no README file.


ID #421 (8/30)
---------------------------------------------
-22 points: There are fairly significant problems with most parts of the assignment. Sphere intersection seems to work OK, but ray generation, plane intersection, and lambertian shading all have issues, and there's only one scene in the submitted assignment (which does not render properly due to the above issues).
In addition: Please submit *all* necessary files (in a .zip or .tar archive). You apparently made some changes to parts of the raytracing framework, which is fine, but you didn't submit the changed parts, and your code does not compile as-is.


ID #465 (33/30)
---------------------------------------------
-2 points: The default scene isn't rendered quite right - it appears a bit more "zoomed in" than expected. Ray generation is probably a bit off.
+5 points: extra credit


ID #515 (25/30)
---------------------------------------------
-5 points: A few problems: I couldn't find any way to render the required additional scenes (and there was only one additional scene image posted on your webpage). Also, there was no README file.


ID #712 (21/30)
---------------------------------------------
-10 points: Your code wasn't running because of problems with your Camera class. With that fixed, spheres showed up properly but not planes (there's a problem with InfinitePlane::Intersect). Also, only the required scene was there - neither of the two others were available.

+3 points: texturing sort of works, but has a lot of problems
