TLDR
This survey discusses the state of the art in motion control of complex, articulated figures and the particular problems of human figure and character animation and an architecture for task animation.Abstract:
Computer animation of three-dimensional objects and figures consists of modeling, rendering, and control problems. This survey discusses the state of the art in motion control of complex, articulated figures. The major approaches to animation control are parametric interpolation schemes, kinetics, inverse kinematics, constraints, dynamics, simulation, and Artificial Intelligence techniques. The particular problems of human figure and character animation and an architecture for task animation are presented. Besides computer graphics animation for its own sake, ergonomics, human factors research and extensions to task level control of multiple figures are target applications.read more

Three-dimensional image processing apparatus for jointed objects
TL;DR: In this article, a 3D joint position storing circuit for storing a three-dimensional coordinate position for each of available joints of an object at each frame for a standard action, and a geometric data storing circuit to store geometric data for at least a portion of the object based on unique coordinate systems.

Defining the Semantics of Verbal Modifiers in the Domain of Cooking Tasks
TL;DR: The semantic analysis of verbal modifiers on which the SEAFACT implementation is based is described, which produces a representation of the task which can drive motion synthesis procedures.

Animation modeling with petri nets
TL;DR: The original formulation for Petri Nets is applied in two animation situations, one modeled as a state machine and another exploring interdependent transitions.

Interpolating splines with local tension, continuity, and bias control
TL;DR: This paper presents a new method for using cubic interpolating splines in a key frame animation system which produces a very general class of interpolating cubic splines which includes the cardinal splines as a proper subset.
Image Analysis of Human Motion Using Constraint Propagation
Joseph O'Rourke,Norman I. Badler +1 more
TL;DR: In this paper, a system capable of analyzing image sequences of human motion is described, which is structured as a feedback loop between high and low levels: predictions are made at the semantic level, and verifications are sought at the image level.
