Simplex Based Animation

چکیده
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 devised a physically based metamorphism algorithm that rests on the intrinsic shape representation of these meshes This algorithm handles transformations between objects of di erent topology or boundary conditions Various simplex mesh shapes were extracted from range images or some triangulated data and then metamorphosed by applying generalized mesh transformations

The Study of Education Based on Animation in Patient’s Performance under Hemodialysis in Emergency Evacuation Selected Hospitals of Aja
Introduction: A disaster evacuation program is one of the most important parts of hospital crisis management. The following study was carried out to determine the effects of animation-based teaching on hemodialysis patients’ performance in an emergency evacuation. Material and Method: In this quasi-experimental study, two out of four AJA Hospitals in Tehran that had hemodialysis wards, were sel...
متن کاملDeveloping EFL Learners' Oral Proficiency through Animation-based Instruction of English Formulaic Sequences
The current pretest-posttest quasi-experimental study attempts, firstly, to probe the effects of teaching formulaic sequences (FSs) on the second or foreign language (L2) learners' oral proficiency improvement and secondly, to examine whether teaching FSs through different resources (i.e. animation vs. text-based readings) have any differentially influential effects in augmenting L2 l...
متن کاملTracking facial features in video sequences using a deformable model-based approach
This paper addresses the issue of computer vision-based face motion capture as an alternative to physical sensor-based technologies. The proposed method combines deformable template-based tracking of mouth and eyes in arbitrary video sequences with a single speaking person with a global 3D head pose estimation procedure yielding robust initializations. Mathematical principles underlying deforma...
متن کاملTeaching Note - An Animated Demonstration of the Uncapacitated Network Simplex Algorithm
O Research (OR) instructors use visualizations to help teach graph algorithms and data structures. Algorithm visualization is an illustration of abstract concepts included in computer algorithms, making use of either static or dynamic (animated) computer graphics. In this paper we present new software that includes an animated demonstration of the uncapacitated primal network simplex algorithm....
متن کاملHyperbolic Pascal simplex
In this article we introduce a new geometric object called hyperbolic Pascal simplex. This new object is presented by the regular hypercube mosaic in the 4-dimensional hyperbolic space. The definition of the hyperbolic Pascal simplex, whose hyperfaces are hyperbolic Pascal pyramids and faces are hyperbolic Pascals triangles, is a natural generalization of the definition of the hyperbolic Pascal...
