We propose a methodology for animating complexmodels based on simplexmesh represen tation and deformation A simplex mesh is characterized by a connectivity between vertices of three and can be obtained by duality from a triangulation In addition to their generality of representation simplex meshes have a compact and unambiguous shape description related to the notion of mean curvature We devise...

This paper shows the interest of basing a mechanical mesh upon an efficient topological model in order to give any simulation the ability to refine this mesh locally and apply topological modifications such as cutting, tear and matter destruction. Refinement and modifications can indeed be combined in order to get a more precise result. The powerful combinatorial map model provides the mathemat...

This paper discusses the use of computer interactive media in a traditional shadow play lesson for elementary students. The researchers digitalized traditional shadow play rules, photos, and other related information by applying twodimensional animation techniques. The instructional material was used to assist the instructor’s teaching, as well as to help the students to understand the major th...

The breakthrough of pipelined microprocessors has brought about a need to teach instruction pipelining in electrical and computer engineering curricula at the undergraduate level to a considerable depth. Although the idea of pipelining is conceptually simple, students often find pipelining difficult to visualize. Only the most talented students assimilate the ideas of how hazard issues are elim...

WPSD (Weighted Pose Space Deformation) is an example based skinning method for articulated body animation. The per-vertex computation required in WPSD can be parallelized in a SIMD (Single Instruction Multiple Data) manner and implemented on a GPU. While such vertex-parallel computation is often done on the GPU vertex processors, further parallelism can potentially be obtained by using the frag...

P. J. Crossno, et. al. * Accepted for presentation at ASME Fluids Engineering Conference, June 20-24, 1993 Washington, D.C. ABSTRACT Scientific visualization is playing an increasingly important role in the analysis and interpretation of massively parallel CFD simulations due to the enormous volume of data that can be generated on these machines. In this paper we will describe the development o...

In this position paper, we describe a novel approach for creating visual stimuli for research on gesture in instruction. The approach is based on a system of computer animation instructor avatars whose gesture is controlled with a script. Compared to video recording instructor actors, the approach has the advantage of efficiency—once the script is written, it is executed automatically by the av...

from applied linguistic point of view, the fundamental question facing the language teachers, methodologists and course designers is which procedure is more effective in fl/sl: learning to use or using to learn? definitely, in order to be a competent language user, knowledge of language system is necessary, but it is not sufficient to be a successful language user. that is why there was a gradu...
