This paper gives a general methodology for symbolic programming of complex 3D scenes and animations. It also introduces a minimal set of animation primitives for the functional geometric language PLaSM. The symbolic approach to animation design and implementation given in this paper goes beyond the traditional two-steps approach to animation, where a modeler is coupled, more or less loosely, wi...

In this paper we describe methods for the generation of real-time facial animation for various virtual actor using high level-actions. These high-level actions allow the user to forget the technical side of the animation, and focus only on the more abstract, more natural, and intuitive part of the facial animation. The mechanisms developed to generate interactive high-level real-time animation ...

To support our research on ASL animation synthesis, we have adopted and enhanced a new virtual human animation platform that provides us with greater fine-grained control of facial movements than our previous platform. To determine whether this new platform is sufficiently expressive to generate understandable ASL animations, we analyzed responses collected from deaf participants who evaluated ...

Creating complex animations of human characters with simple high-level commands has been a design goal of animation software for a long time. Procedural animation is an effective approach in this direction aiming to create animation with algorithmic description of how a motion is generated. Nevertheless, creating coordinated motion between animated characters has always been a great challenge b...

This paper presents a new approach to create 3D visualization from discrete simulation results. This approach connects discrete event simulation directly to 3D animation with its novel methods that analyze and convert discrete simulation results into animation events to trigger 3D animation. In addition, it constructs a 3D animation framework for the visualization of discrete simulation results...

ÐIn this paper, we consider accelerated rendering of high quality walkthrough animation sequences along predefined paths. To improve rendering performance, we use a combination of a hybrid ray tracing and Image-Based Rendering (IBR) technique and a novel perception-based antialiasing technique. In our rendering solution, we derive as many pixels as possible using inexpensive IBR techniques with...
