Processing free form objects within a Product Development Process framework
TypeChapitres d'ouvrages scientifiques
The purpose of the chapter is then to review: (1) the stages of a product development pro- cess (PDP) where free-form shapes appear and are subjected to aesthetic and functional require- ments; (2) the modeling, sketching, and modification activities illustrating how free-form surfaces can be processed and what are the corresponding difficulties faced during these tasks; (3) the con- tributions of our community to solve some of these issues, and the problems which are still open.

Incorporating free-form features in aesthetic and engineering product design: State-of-the-art report PERNOT, Jean-Philippe; FALCIDIENO, Bianca; GIANNINI, Franca; LEON, Jean-Claude (Elsevier, 2008)The use of free-form shapes has become mainstream to design complex products that have to fulfil engineering requirements as well as aesthetic criteria. Even if today’s CAD systems can easily represent free-form shapes by ...
CHEUTET, Vincent; CATALANO, Chiara Eva; PERNOT, Jean-Philippe; FALCIDIENO, Bianca; GIANNINI, Franca; LEON, Jean-Claude (Elsevier, 2005)This paper addresses the designers’ activity and in particular the way designers express an object shape in 2D sketches through character lines and how these lines form a basis for sketching shapes in 3D. The tools currently ...
LOU, Ruding; GIANNINI, Franca; PERNOT, Jean-Philippe; MIKCHEVITECH, Alexei; VERON, Philippe; FALCIDIENO, Bianca; MARC, Raphael (Tools and Methods for Competitive Engineering (TMCE'10), 2010)Nowadays, the mainstream methodology for product behavior analysis and improvement relies on the fol-lowing steps: 1) conceptual solution proposal and CAD prototyping, 2) mesh model creation for Finite Element (FE) analysis, ...
LOU, Ruding; PERNOT, Jean-Philippe; GIANNINI, Franca; VERON, Philippe; FALCIDIENO, Bianca (Emerald, 2015)Purpose – The purpose of this paper is to set up a new framework to enable direct modifications of volume meshes enriched with semantic information associated to multiple partitions. An instance of filleting operator is ...
LI, Zongcheng; GIANNINI, Franca; PERNOT, Jean-Philippe; VERON, Philippe; FALCIDIENO, Bianca (Springer, 2016)Today, digital data such as 2D images, 3D meshes and 3D point clouds are widely used to design virtual environments (VE). Most of the time, only one type of those multimodal data is used to describe and specify the shapes ...
