SMRT Reading Group

Friday 1:30PM, Room: ICCS304

This is the web page of the reading group SMRT (SensoriMotor Reading and Thinking).
To remember the acronym, think of Homer Simpson singing, "I am so smart, I am so smart, S-M-R-T."

The topic for the SMRT reading group is currently "Physically-Based Animation". Each week someone presents a paper/tutorial, followed by discussion. The focus will be on simulation: How to derive animations for various materials relating to the human body and fabrics. Ideally we will focus on more recent (ex. SIGGRAPH 2019) papers but there will be room for relevant, older papers. Textbook chapters are also welcome, so long as they are relevant and accessible to everyone.

If you want to be informed about upcoming papers, please subscribe to the mailing list by sending a message to, with the body "subscribe smrt-l". Or just click here.

A schedule of upcoming papers can be found below under the heading Upcoming Papers. Under the heading Finished Papers is a log of earlier topics. A list of papers to potentially discuss in the future are listed under Suggested Papers. If you want more information, have further suggestions for papers to discuss, or want to be added to the schedule, please contact Seung Heon Sheen.

We will structure each session around answering the following questions:
What problem are the authors addressing?
How does it relate to simulation?
How does it work?
How does it compare to existing methods?
What are the benefits; what were the drawbacks?
