In this paper, we describe a dynamic control algorithm that allows a humanoid character to swim through a fluid. The swimming is physically-based, whereby the character applies simulated muscle forces in order to drive the body through the motions of a breaststroke. The interaction between the moving body parts and a fluid dynamics system results in drag forces that cause the swimmer’s body to ...

Rigging an arbitrary 3D character by creating an animation skeleton is a time-consuming process even for experienced animators. In this paper, we present an algorithm that automatically creates animation rigs for multicomponent 3D models, as they are typically found in online shape databases. Our algorithm takes as input a multi-component model and an input animation skeleton with associated mo...

Physically-based animation techniques enable more realistic and accurate animation to be created. We present a fully physically-based approach for efficiently producing realisticlooking, natural animations of facial movement, including animation of expressive wrinkles. This involves simulation of detailed models using a GPU-based total Lagrangian explicit dynamic finite element (TLED FE) system...

This paper shows how research in Computer Animation leads to virtual actors who will be able to possess their own animation. A high-level approach consists in specifying the animation in terms of tasks. The animator can only specify the broad outlines of a particular movement and the animation system fills in the details. Examples will be shown in grasping and walking. We also show the needs fo...

background and purpose: active learning, combined with computer-assisted instruction, can enhance medical students’ performance and learning. this article is an attempt to introduce a new web-based approach to information technology instruction for medical students. methods: eight topics were selected to be instructed in web-based workshops. phpbb forum was used for web-based collaborative lear...

This article is organised in five main sections. First, the sub-area of task-based instruction is introduced and contextualised. Its origins within communicative language teaching and second language acquisition research are sketched, and the notion of a task in language learning is defined. There is also brief coverage of the different and sometimes contrasting groups who are interested in the...

Interactive simulation is made possible in many applications by simplifying or culling the finer details that would make real-time performance impossible. This paper examines detail simplification in the specific problem of collision handling for rigid body animation. We present an automated method for calculating consistent collision response at different levels of detail. The mechanism works ...

We have been developing an Intelligent Tutoring System to teach students to analyze and debug C++ programs for semantic and run-time errors. In this tutor, we have used Model-Based Reasoning for domain modeling and explanation generation. In addition, we plan to use it for program animation. In this paper, we will present our design of the tutor, and results from evaluating one instance of the ...

Interactive implicit modelling with complex skeletons was recently improved with the introduction of primitives de ned at di erent LODs. These implicit primitives use a subdivision curve as a skeleton. In this paper an extension to this representation is presented, in order to make it suitable for the interactive modelling and animation of soft objects in contact situations. The rst contributio...
