Course Text • Published last year! • 4th ed. is full colour • I will assign readings - not sequentially though • Not 100% necessary to pass this course, but do buy it!
Caltech Cornell Stanford UBC UC Berkeley
These slides are not lecture notes!
Grading • 50% - Assignments • 20% - Midterm (in class Tuesday, October 30th) • 30% - Final Exam • A double-sided, letter-sized, hand-written page will be allowed as reference for each exam
Assignments • Total of five assignments to be completed in pairs: 1. Line and polygon geometry 2. Image effects 3. Curves and splines 4. Ray tracing 5. Real-time rendering
Completing the Assignments • Each assignment has written and programming parts • Written component is due ahead of program • Programming component can be completed on any platform, but up to you to ensure your TA can run it! • Your TAs will help you with the practicalities of coding • First tutorial is on Monday, September 10th!
Working With a Partner • You may work with a partner for each assignment • Ideally learn more, learn faster, and more fun • Two’s company, but three’s a crowd! • You must pick a different partner for each assignment • See others’ approach to problems and programming • Experience up to five different styles this semester!
Tips for Working With a Partner • Choose a partner with a similar skill level • Work on all aspects of the assignment together • Schedule time to get together in person • Practice “pair programming” • Resist the temptation to “divide and conquer” the work • You’ll likely both end up worse off
Assignments & Late Days • You’ll be allowed five grace “late days” to use as needed • Late day is 24 hour period • Cannot be used for written component • Both partners must have and use the requisite number of late days to submit the assignment late! • Don’t ask me for extensions!
Bonus Opportunities • All assignments will have bonus opportunity • Binary designation (you get it or you don’t) • No point credit value! • Possibly your ticket to an A+ in this course: • A grade some bonuses = A+ • A- grade and lots of bonuses = A+
