2D semantic sketcher for car aesthetic design

چکیده
RÉSUMÉ. Cet article présent une première étape dans l’élaboration d’un environnement de modélisation sémantique pour les premières étapes de la conception d’une voiture. Jusqu’à présent, la génération et la manipulation de forme en conception esthétique se basent toujours sur des outils géométriques de bas niveau qui proviennent du paradigme classique de la CAO (Conception Assistée par Ordinateur) D’un autre côté, la conception d’un produit est basée principalement sur la créativité des stylistes et sur des contraintes de haut niveau. Par conséquent, un tel environnement se base d’abord sur une structuration de la sémantique présente dans les premières esquisses 2D du produit. Pour manipuler ces esquisses, une grammaire de processus est intégrée pour décrire et manipuler les courbes. Enfin, cette grammaire a été implémentée grâce à un moteur de déformation adapté aux courbes NURBS.

Producing design diagrams from declarative descriptions
The declarative language Ruby provides a coherent framework for representing and developing designs. Sketching diagrams for Ruby programs by hand is, however, time-consuming and error-prone. This paper describes a design sketcher which automates the production of a diagram from a Ruby description.
متن کاملAcceleration-Based Quality Assessment of Railway Tracks using a 2D simulation model and recorded track data
Car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. Though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. To do so, car body acceleration is determined using a 10 DOF simulat...

متن کاملDrawing Electroacoustic Music
The initial stages of creative design often involve sketching. Electroacoustic composition is no exception to this. Paradoxically, the technologies that enable this form of composition provide little support for the sketching process itself. In this paper we first present evidence for the importance of paper-and-pen sketching in current practice and discuss two strategic representational functi...
