EE 4702-1 - What's New

Grading Update 6: Grades posted to Workday Student. I'm not going to post these on the Web. Not because they're bad, just to save time. Thank you for your effort in GPU programming! Have a good winter break!

Grading Update 5: I haven't yet decided on the course grades. I'll need to consult the pillow again. If it's any consolation, the longer I think the more lenient I get. The next grading update should be posted about 18:00 tomorrow.

Grading Update 4: Final Exam Grades Ready The median grade is better than the 2024 final exam, and some did well. One person aced the exam! But, many did poorly. The median is 41 and the range is [7,100]. Many could have done much better on Problem 1, the geometry shader. When AGI takes over there will be no need to think, but we are not there yet ... AFAIK. To find out your grade or just to see the aliases click here. Course grades may be posted tomorrow or Monday. The next grading update should be posted about 18:00 tomorrow.

Grading Update 3: Problems 1-5 graded, Problem 6 partially graded. Final exam grades will be posted later tonight, perhaps in an hour. So, the next grading update will be posted at about 19:00, maybe a bit later.

Grading Update 2: Problem 1 graded, Problem 2 partially graded. Final exam grades should be available tomorrow. Maybe course grades too, but I might need to consult with the pillow. The next grading update should be posted tomorrow by about approximately 18:00.

Grading Update 1: Linked the Final Exam to the previous work page. Grading will start tomorrow afternoon, or perhaps earlier. Final exam grades may be available Saturday. The next grading update will be posted tomorrow by approximately 18:00.

I'd like to thank everyone for responding to my request for a sign of life (course participation). Everyone that was on the registration list responded in some way, and so no one was marked not attending.

Linked recent material to the lecture slides page.

During class today some students brought up the possibility that the distortion equation described in the Homework 1 handout does not correspond to the distortion shown in the screenshot in the handout. I've double-checked the solution, which was used to generate the screenshots in the handout, and it does appear to match the equation in the handout. Though the equation shown is correct, the handout will be has been updated with more screenshots.

If your code exits with an abort error it may be because the index used for fb_dup is out of range. To check whether that is the case, and if so, to look at how the index is computed run hw01-debug under gdb and when it prints the error message first type where to get a call stack (back trace). Then locate the frame where your code is (look for "hw01.cc:LINE" at the end of a frame entry). Then type frame X where X is the frame where your code executed. Use up and down to move up and down. You can print variable values and expressions using the command p, for example, p x or p y*win_width. To get the size of fb_dup type p fb_dup.size().

The deadline for Homework 1 changed to Tuesday evening. In Problem 2 be careful about keeping the index to fb_dup in the correct range (see the end of the homework handout). If an out-of-range index is use execution will exit with an error.

Homework 1 assigned, due Monday, 8 Tuesday, 9 September 2025.
