Kinematic Motion Retargeting for Contact-Rich Anthropomorphic Manipulations
Arjun S. Lakshmipathy, Jessica K. Hodgins, Nancy S. Pollard
Hand motion capture data is now relatively easy to obtain, even for complicated grasps; however this data is of limited use without the ability to retarget it onto the hands of a s…
Simulation and Retargeting of Complex Multi-Character Interactions
Yunbo Zhang, Deepak Gopinath, Yuting Ye +3
We present a method for reproducing complex multi-character interactions for physically simulated humanoid characters using deep reinforcement learning. Our method learns control p…
Animating Fracture
James F. O'Brien, Jessica K. Hodgins
We have developed a simulation technique that uses non-linear finite element analysis and elastic fracture mechanics to compute physically plausible motion for three-dimensional, s…
Combining Active and Passive Simulations for Secondary Motion
James F. O'Brien, Victor B. Zordan, Jessica K. Hodgins
Objects that move in response to the actions of a main character often make an important contribution to the visual richness of an animated scene. We use the term "secondary motion…
Animating Explosions
Gary D. Yngve, James F. O'Brien, Jessica K. Hodgins
In this paper, we introduce techniques for animating explosions and their effects. The primary effect of an explosion is a disturbance that causes a shock wave to propagate through…
Automatic Joint Parameter Estimation from Magnetic Motion Capture Data
James F. O'Brien, Robert E. Bodenheimer, Gabriel J. Brostow +1
This paper describes a technique for using magnetic motion capture data to determine the joint parameters of an articulated hierarchy. This technique makes it possible to determine…
Graphical Modeling and Animation of Brittle Fracture
James F. O'Brien, Jessica K. Hodgins
In this paper, we augment existing techniques for simulating flexible objects to include models for crack initiation and propagation in three-dimensional volumes. By analyzing the…
Animating Sand, Mud, and Snow
Robert W. Sumner, James F. O'Brien, Jessica K. Hodgins
Computer animations often lack the subtle environmental changes that should occur due to the actions of the characters. Squealing car tires usually leave no skid marks, airplanes r…
Perception of Human Motion with Different Geometric Models
Jessica K. Hodgins, James F. O'Brien, Jack Tumblin
Human figures have been animated using a variety of geometric models including stick figures, polygonal models, and NURBS-based models with muscles, flexible skin, or clothing. Thi…
Animating Human Athletics
Jessica K. Hodgins, Wayne L. Wooten, David C. Brogan +1
This paper describes algorithms for the animation of men and women performing three dynamic athletic behaviors: running, bicycling, and vaulting. We animate these behaviors using c…
Dynamic Simulation of Splashing Fluids
James F. O'Brien, Jessica K. Hodgins
In this paper we describe a method for modeling the dynamic behavior of splashing fluids. The model simulates the behavior of a fluid when objects impact or float on its surface. T…
