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.

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 ...
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 ...
LOU, Ruding; GIANNINI, Franca; FALCIDIENO, Bianca; PERNOT, Jean-Philippe; VERON, Philippe; MIKCHEVITCH, Alexei; MARC, Raphael (World Scientific Publishing Company, 2010)Behaviour analysis loop is largely performed on virtual product model before its physical manufacturing. The last avoids high expenses in terms of money and time spent on intermediate manufacturing. It is gainful from the ...
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 ...
LOU, Ruding; PERNOT, Jean-Philippe; VERON, Philippe; GIANNINI, Franca; FALCIDIENO, Bianca; MIKCHEVITCH, Alexei; MARC, Raphael (IEEE Computer Society, 2010)Advances in modeling of discrete models have allowed the development of approaches for direct mesh modeling and modification. These tools mainly focus on modeling the visual appearance of the shape which is a key criterion ...
