Programmable Motion Effects (assigned)

by Daniel January 23, 2011 Assignment 1

1. Sentence: “In our work, we experiment with motion depiction as a first-class entity within the rendering process.” (abstract) 2. Problem: Unlike motion in 2d drawings and hand drawn animation, computer animation is less flexible in the way that motion is depicted. For computer animation, usually a constant time interval blurring between two positions is […]

Example-Based Wrinkle Synthesis for Clothing Animation

by Nathan Mitchell January 23, 2011 Assignment 1

Assigned Paper: Found on authors website here Sentence:  In this paper, we propose a fast clothing animation system that combines synthesized fine wrinkle details with coarse cloth dynamics. Problem:  Traditional cloth simulation has difficulties working with clothing that is continually in close contact with other objects. Instead simulate the coarse grain aspects of the cloth […]

Movie Reshape: Tracking and Reshaping of Humans in Videos

by Michael Correll January 23, 2011 Assignment 1

1. We therefore propose in this paper on of the first systems in the literature to easily perform holistic manipulation of body attributes of human actors in video. 2. Video editors want to alter body attributes, but this can be computational intensive, and since body attributes are highly mutually correlated doing the edits locally doesn’t […]

BetweenIT: An Interactive Tool for Tight Inbetweening

by Nathan Mitchell January 23, 2011 Assignment 1

Assigned Paper: Found on authors website here Sentence:  We present a novel technique for stroke interpolation from only two keys which combines a stroke motion constructed from logarithmic spiral vertex trajectories with a stroke deformation based on curvature averaging and twisting warps. Problem:  The process of tight inbetweening by hand requires large amounts of time […]

Modeling style and variation in human motion

by Adrian Mayorga January 23, 2011 Assignment 1

Paper 1. Sentence: This paper presents a novel method to simultaneously model both style and variation in human motion (1st sentence, 2nd paragraph) 2. Problem: Individually capturing the motions for all characters in a high density crowd animation is impractical, which leads to the use of distracting motion clones. 3. Key Idea: Model Style and […]

Gesture Controllers

by Adrian Mayorga January 23, 2011 Assignment 1

Paper 1. Sentence: In this paper, we introduce gesture controllers, a new method for automatically generating body language animations from live speech (1st sentence, 2nd paragraph). 2. Problem: Non-verbal communication in virtual environments is either manually controlled or non existent. Automatically generate gestures instead. 3. Key Idea: Separate gesture kinematics from shape and learn each […]

Fixed Readings…

by Mike Gleicher January 23, 2011 News

There were some broken links in the Rotations reading (now fixed – I think). This prompted me to make a new “protected reader” for this class. The web directory https://graphics.cs.wisc.edu/Courses/Readers/Animation11/ will be a place where all of the readings that are only for this class (because of copyright restrictions) will go. Note: this uses the […]

2.5D Cartoon Models (chosen from List)

by Subhadip Ghosh January 23, 2011 Assignment 1

1. Sentence: We show how 2D vector art drawings of a cartoon from different views can be used to generate a novel structure, the 2.5D cartoon model, which can be used to simulate 3D rotations and generate plausible renderings of the cartoon from any view. (2nd sentence, Abstract) 2. Problem: Generating a 3D model is […]

Robust Physics-Based Locomotion Using Low-Dimensional Planning (chosen from List)

by Subhadip Ghosh January 23, 2011 Assignment 1

1. Sentence: This paper introduces a locomotion controller for full-body 3D physics-based characters that plans joint torques by optimizing a low dimensional physical model (1st sentence, 2nd paragraph). 2. Problem: Existing locomotion models are gait specific and do not plan control over multiple foot-steps. 3. Key Idea: At each instant of the simulation an optimized […]

Fast and Efficient Skinning of Animated Meshes (assigned)

by Subhadip Ghosh January 23, 2011 Assignment 1

1. Sentence: We introduce a technique that produces quite accurate skinning decompositions with low bone counts (1st sentence, 5th paragraph Introduction) 2. Problem: Skinning methods typically perform well only for a certain class of input sequences and often require long pre-processing times. 3. Key Idea: Use an algorithm based on iterative coordinate descent optimization which […]
