Regrading Course Information � to request assignment or exam regrade � course web page is main resource � must submit detailed written explanation of � http://www.ugrad.cs.ubc.ca/~cs314/Vmay2005 why you think the grader was incorrect for the � updated often, reload frequently particular problem that you are disputing � newsgroup is ubc.courses.cpsc.414 � I may regrade entire assignment � note old course number still used � thus even if I agree with your original request, � readable on or off campus your score may end up higher or lower � (no WebCT) � � Labs Teaching Staff � attend two labs per week, 3 sessions each � instructor: Dr. Munzner � Tue/Thu 11-12, 3-4, 4-5 � tmm@cs.ubc.ca � Thursday afternoon better than Thu morning � office hrs in CICSR 011 � Tuesdays: example problems in spirit of � Mon 4:30-5:30 written assignments and exams � TAs: Warren Cheung, Greg Kempe � Thursdays: help with programming projects � wcheung@cs.ubc.ca � no deliverables � kempe@cs.ubc.ca � strongly recommend that you attend � use newsgroup not email for all questions that other students might care about � �� Required Reading Learning OpenGL � this is a graphics course using OpenGL � not a course *on* OpenGL � Fundamentals of Computer Graphics � upper-level class: learning APIs mostly on � Peter Shirley, AK Peters your own � only minimal lecture coverage � OpenGL Programming Guide, v 1.4 � basics, some of the tricky bits � OpenGL Architecture Review Board � OpenGL Red Book � v 1.1 available for free online � many tutorial sites on the web � nehe.gamedev.net � readings posted on schedule page �� �� Page 2 2

Plagiarism and Cheating Citation � don’t cheat, I will prosecute � cite all sources of information � insult to your fellow students and to me � web sites, study group members, books � programming and assignment writeups must be � README for programming projects individual work � end of writeup for written assignments � exception: project 3 can be team of two � http://www.ugrad.cs.ubc.ca/~cs314/Vmay2005/policies.html#plag � can discuss ideas, browse Web � but cannot just copy code or answers � you must be able to explain algorithms during face-to- face demo � or no credit for that part of assignment, possible prosecution �� �� What is Computer Graphics?
