Oriented Particles: A Tool for Shape Memory Objects Modelling
نویسندگان
چکیده
Originally introduced to render probabilistic objects, particle systems are now used in a wide range of applications. Oriented particle systems were designed as a dynamic modelling tool for describing 3D free-form objects. We propose a new method using oriented particle systems to dynamically simulate 3D deformable objects that may either come back to their initial shape or break during animations. This method can be used in a physically based animation system. We also propose a new more robust expression for the attraction/repulsion interaction between particles. Resume Introduits en informatique graphique pour pallier aux lacunes de la geometrie c1assique, les systemes de particules sont maintenant utilises dans de nombreux types d ' applications. Les systemes de particules orientees ont ete crees pour modeliser des surfaces tri-dimensionnelles de forme libre. Nous proposons une nouvelle methode utilsant des systemes de particules orientees pour simuler dynamiquement des objets deformables . Cette methode peut etre utilisee pour I'animation par ordinateur avec des modeles physiques. Nous presentons aussi une nouvelle expression pour les interactions d'attraction/repulsion utile pour tous les systemes de particules (orientees ou non) .

Titanium Oxide (TiO2) Coatings on NiTi Shape Memory Substrate Using Electrophoretic Deposition Process
The aim of the present research is to convert bioinert surface of NiTi to bioactive and biocompatible surface. In order to develop a bioactive and corrosion resistant film on NiTi, electrophoretic deposition process was done and TiO2 particles were deposited on the NiTi surface. Suspensions including TiO2 particles were prepared using a mixture of acetone and n-butanol (0%, 30%, 60%, 80% and 10...
متن کامل3D Modelling of Under Ground Burried Objects Based on Ground Penetration Radar
There is a growing demand for mapping and 3D modelling of buried objects such as pipelines, agricultural hetitage, landmines and other buried objects. Usually, large scale and high resolution maps from these objects are needed. Manually map generation and modeling of these objects are cost and time consuming and is dependent on lots of resources. Therefore, automating the subsurface mapping and...
متن کاملObjects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques
Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...

متن کاملModeling and Evaluation of Stochastic Discrete-Event Systems with RayLang Formalism
In recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. In the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. In this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (OOPLs) us...
