Clearer Instructions for Assignment 1

by Mike Gleicher January 23, 2011 News

Since it might not be so clear: For assignment 1, you are supposed to enter each of your papers as a posting, not as a comment on the assignment. (The assignment itself is a posting). This is all a bit of a wordpress-ism. Sorry if it wasn’t clear. This whole setup can be made to […]

Bidirectional Search for Interactive Motion Synthesis

by xlzhang January 23, 2011 Assignment 1

1.     This paper “presents an approach to improve the search efficiency for near-optimal motion synthesis using motion graphs.” (Abstract) 2.     Many successful techniques for realistic motion synthesis are based on motion graphs, but the search complexity for even a near-optimal solution increases exponentially as the length of the desired sequence increases. 3.     Apply bi-directional A* […]

Point Cloud Glue: Constraining simulations using the Procrustes transform

by xlzhang January 23, 2011 Assignment 1

1.     The paper presents a new method of defining constraints between deformable objects in physical simulation, called “Point Cloud Glue”. 2.     Existing methods of defining constraints that use Barycentric coordinates are simple, but limited, and unstable unless weights are all non-negative. 3.     Point Cloud Glue works by computing the nearest-fit rigid transform (the orthogonal Procrustes […]

Face/Off: Live Facial Puppetry

by xlzhang January 23, 2011 Assignment 1

1.     This paper presents a complete integrated system for live facial puppetry that enables high resolution real-time facial expression tracking with transfer to another person’s face. (Abstract) 2.     The current methods for facial performance capture are complex, rely heavily on manual assistance, and are often accompanied by long turn-around times. 3.     A low-cost […]

Animating Non-Humanoid Characters with Human Motion Data

by xlzhang January 23, 2011 Assignment 1

1.   This paper presents a method for generating whole-body skeletal animations of non-humanoid characters from human motion capture data. (Intro, paragraph 1) 2.    Often, characters that are inspired by animals or inanimate objects are expected to be anthropomorphic, but most data-driven techniques for animation, such as keyframing, do not work for these characters due […]

Programmable Motion Effects

by Aaron Bartholomew January 23, 2011 Assignment 1

Sentence: Stylize the motion of an object in order to elicit an aesthetic response   Problem: Production renderers are hard-wired to deliver realistic motion blur, which limits the stylistic effects possible for representing motion (cannot create ‘comic-book’ effects such as speed lines, stroboscopic copies, streaking,…).   Key: Use a surface shader with global information to […]

2.5D Cartoons

by Aaron Bartholomew January 23, 2011 Assignment 1

1.  Sentence: This paper seeks to bring 2D vector art drawings into 3D by simulating rotations with plausible renderings from any viewpoint. 2.  Problem: In order to have cartoons in a 3D environment, up to now, a 3D model needed to be constructed and rendered in an NPR-fashion.  This requirement limits stylistic (aesthetic and animated) […]

Video-Based Reconstruction of Animatable Human Characters

by Aaron Bartholomew January 23, 2011 Assignment 1

Sentence: This paper presents a performance capture approach that uses multi-view video recordings and incorporates physically-based cloth to reconstruct a rigged, fully-animatable virtual double of a real person in loose apparel.   Problem: There is a significant difference in visual quality of virtual human characters in off-line and real-time renderings; this is due to the […]

Assignment 1 (Papers) assignments

by Mike Gleicher January 21, 2011 Assignments

With any luck, you have each gotten an email with 2 papers assigned for Assignment 1. I either used the “official” email address in the CS roster, or some email address that my mailer remembers for you. If you didn’t get the email, I have put initials next to papers on the list. With one […]

What’s happening in 777 (1/21-1/31)

by Mike Gleicher January 20, 2011 News

A lot of posts all over the place, but here’s the story for the next week (with what you should be doing): Friday, 1/21 – Assignment 0 is due. We’ll start talking about rotations and transforms. Monday 1/24 – Assignment 1 is due. We’ll talk about the results (what kinds of things go into animation […]
