Course web for the Spring 2019 Computer Graphics Class

Month: March 2019

The Week in Vis: April 1 – April 5

We’re back to normal schedule. Workbooks, lectures.

Week 10 ( Mon, Apr 1 – Fri, Apr 5): Fancier Texturing and Lighting

Mon, Apr 1: Workbook 08: Meshes and Textures assigned
Tue, Apr 2: Lecture: More Meshes and Textures
Thu, Apr 4: Lecture: Lighting Models
Fri, Apr 5: Workbook 08: Meshes and Textures due

The big thing this week is that the workbook is becoming more about preparation for the Graphics Town project. We’re still taking small steps to emphasize learning the concepts. But soon, you’ll have a whole world in your web browser…

The Week in CS559: Break and Post-Break Edition (March 25-29)

The week before break was an unusual week, with the Exam, and the re-scheduled Workbook 6. The week after break, things will return to our normal schedule.

Week 9 ( Mon, Mar 25 – Fri, Mar 29): Local lighting and texturing

Mon, Mar 25: Workbook 07: 3D Hierarchical Models assigned
Tue, Mar 26: Lecture: Kinematics and Inverse Kinematics
Thu, Mar 28: Lecture: Meshes and Textures
Fri, Mar 29: Workbook 07: 3D Hierarchical Models due

Workbook 7 should be available during break so you can get a head start if you like.

Note that during break. responses to Piazza by the course staff may be slower than usual. The TAs will not hold their usual office hours.  Also note that Prof. Gleicher will not have his office hours the week after break.

Graphics Beyond 559 (summer and next year)

Short version: If you think you like Computer Graphics (the subject and/or the class), please come talk to me. (This is an occassion where sending email is OK).

There are many opportunities to be involved in graphics things beyond the class:

  • Summer opportunities – we have opportunities for students work on projects of all kinds. There are opportunities to work for pay or for credit.
  • CS559 Peer Mentors – we would like to have peer mentors for CS559 next year (fall and spring). These are paid positions. You can ask Jay about the experience.
  • Fall project opportunities – there are opportunities to work on projects for credit or pay during the academic year.

If you think you may be interested in any of these things, please contact me: send me email, come to office hours, or even say hello after class one day.

The Curve for the Midterm

As you would expect in a graphics class, the curve is a piecewise polynomial!

The curve is a continuous function – we map to numbers in the range 0-4, but we don’t round. We’ll do rounding when we compute the final grades. We consider boundary cases carefully when we determine grades at the end of the semester.

The Median for the exam was 26. If you scored the median or above you got better than a B.

If your score is below 25, your grade is: 3 * (score-10)/15 (no one scored less than 10)

If your score is above 25-34, your grade is 3 + (score-25)/10

If your score is 35 or above, your grade is 4.


Exam grades

We have the “raw” exam scores.

However, I am not going to release them until I can tell you what the curve is.

The median score is about 25/26 of of 39.

I expect to post an answer key this evening, and grades on or before Friday.

Lecture 14 Materials

Don’t worry if you don’t get the rotations stuff the first time through. It is challenging, and usually takes looking at it multiple times and working with it a bit.
