The reading for Friday (that I'd like you to look over, and then read in detail after the class is):
Motion Graphs by Kovar, Gleicher and Pighin (see also the Motion Graphs web page)

Another paper to look at is:
Snap Together Motion by Gleicher, Shin, Kovar, and Jepsen (see also the STM web page). With this paper, try to understand why it is different than the original Motion Graphs.

There are two other papers that are very similar to Motion Graphs, that appeared at the same time as motion graphs. I'm going to suggest that you read them over break. (I don't have copies to put online right now)

Hopefully, today's reading has piqued your interest in Kalman Filters. There is a ton of information about them at Greg Welch and Gary Bishop's web site about them.

i highly recommend their introductory paper, as well as the chapter by maybeck that they provide.

We'll "meet" today in B240. The idea will be to use the web to have a little bit of a scavenger hunt for information on motion capture systems. Its an experiment.

I had a mistake on the web page (that I think I've fixed). The reading for wednesday is: 16-Gleicher-MoCapProc.pdf.

The reading for Monday (intro chapter of a book I haven't written) is very light, and is mainly there to give you an idea of why mocap is hard. A lot of the stuff I would want you to read about would be the middle of the book, but since that hasn't been written, we're kindof stuck.

The reading for Wednesday is about one type of motion capture marker processor. The discussion will be more general (about motion capture processing).

Friday's reading is a paper about computer puppetry. This paper may be a bit hard without more background. I suggest you read through it once to get the basic idea, and we'll discuss the details in class. You might want to revisit it after the lecture.

There is a link to P1 on the left side of the web page.

A large number of BVH files can be found in /p/graphics/public/Data/Motion.

The calendar page has been updated (click the link). While Monday is a "free" day (we'll watch films and talk about projects), there is a lot of reading for later in the week. I am not sure where class will be on Monday.

For the Tolani et. al. paper, you only need to read up to and including section 2.

The readings for rotations are:

• Practical Parameterization of Rotations Using the Exponential Map. F. Sebastian Grassia. Published in the Journal of Graphics Tools. (required)
• Animating Rotation with Quaternion Curves. Ken Shoemake. SIGGRAPH '85 (note: this version is corrected from the original). (required)
• Rotating Objects Using Quaternions Nick Bobick. Game Developer Magazine.
  This is easier to read than the others, so you may find it useful.
• General Construction of Time Domain Filters for Orientation Curves. Jehee Lee and Sung Yong Shin. IEEE TVCG. There is one page (121) that has one of the best (if not the best) explanation of what the exponential map is. The rest of the paper is really good too.

The directory /p/course/cs777-gleicher/public/html/ArtAssign should be writable by everyone in the class. Please place your video (as an AVI file), a picture or 2 (as a JPEG), and a ".txt" file describing it (title, names, 1 or two sentence description).

Class on Monday will be in B240.

Later in the semester, you will need to read a book on film. Some suggestions are here.

My suggestion is to read the Pittsburgh Filmmakers shot by shot, since its such a quick read. There are many copies around (ask someone who took the class in the past).

If several of you want your own copies, there's a 20% discount if you buy more than one, so order together.

The lamp ad that Liz mentioned in class on Wednesday is at http://www.cs.wisc.edu/graphics/Courses/cs777-2004/Movies/lamp.mpeg.

If you watch it, make sure to have the sound turned on. Its important.

Later in the semester, you will have to watch it and analyze it. For now, just enjoy it.

Info about the art assignment has been posted. Click the assignments button on the left hand side.

For Monday, the reading is John Lasseter's Principles of Traditional Animation paper.

There will be no readings for Wednesday, January 28.

For Friday, January 30, please read Ed Catmull's original 3D animation system and Leffler et al. paper about MENV.

Also, please find a partner and start learning about MAYA!

The Walter and Eliza Hall Institute of Medical Research, creators of the DNA animation seen in class, have additional 3D animation sequences available on the web. They can be seen at WEHI-TV Movies.

In honor of the snow day, we will meet in the graphics lab (1347 CS) and watch cartoons. Bring your own hot chocolate and popcorn.
