“…Free-form CAD surfaces are not necessarily associated with a closed-form mathematical definition and created through artistic/ sculpturing [4,36,73] or reverse engineering measurements [75] of random point clouds. This open framework also allow for morphing [11,18] and direct manipulation of surfaces through a limited number of intuitive parameters.…”

The first version of an anatomy editing/surgical planning tool (SURGEM) targeting anatomical complexity and patient-specific computational fluid dynamics (CFD) analysis is presented. Novel three-dimensional (3D) shape editing concepts and human-shape interaction technologies have been integrated to facilitate interactive surgical morphology alterations, grid generation and CFD analysis. In order to implement "manual hemodynamic optimization" at the surgery planning phase for patients with congenital heart defects, these tools are applied to design and evaluate possible modifications of patient-specific anatomies. In this context, anatomies involve complex geometric topologies and tortuous 3D blood flow pathways with multiple inlets and outlets. These tools make it possible to freely deform the lumen surface and to bend and position baffles through real-time, direct manipulation of the 3D models with both hands, thus eliminating the tedious and time-consuming phase of entering the desired geometry using traditional computer-aided design (CAD) systems. The 3D models of the modified anatomies are seamlessly exported and meshed for patient-specific CFD analysis. Free-formed anatomical modifications are quantified using an in-house skeletization based cross-sectional geometry analysis tool. Hemodynamic performance of the systematically modified anatomies is compared with the original anatomy using CFD. CFD results showed the relative importance of the various surgically created features such as pouch size, vena cave to pulmonary artery (PA) flare and PA stenosis. An interactive surgical-patch size estimator is also introduced. The combined design/analysis cycle time is used for comparing and optimizing surgical plans and improvements are tabulated. The reduced cost of patient-specific shape design and analysis process, made it possible to envision large clinical studies to assess the validity of predictive patient-specific CFD simulations. In this paper, model anatomical design studies are performed on a total of eight different complex patient specific anatomies. Using SURGEM, more than 30 new anatomical designs (or candidate configurations) are created, and the corresponding user times presented. CFD performances for eight of these candidate configurations are also presented.

“…In this kind of software, 3D sketches are produced by manipulating a basic primitive shape into complex ones representing concepts of design (Pernot, Falcidieno, Giannini, & Leon, 2008;Cheutet et al, 2005). Manipulation is provided by different means.…”

Design Studies. 34(2):264-284. doi:10.1016/j.destud.2012.09.001. An Exploratory Study on the Use of Digital Sculpting in Conceptual Product Design AbstractThe product design process involves intensive manipulation of graphical data, from pencil sketches to CAD files. The use of graphic software is common among professionals in this field.Despite this, the conceptual design stage remains intensive in paper and pencil work, as CAD systems are still too rigid to allow a creative production of concepts. In this paper the use of digital sculpting software is proposed as a way of producing 3D sketches in the early stages of the process. An experiment is conducted to determine to which extent 3D sculpt sketches can be considered as a suitable tool for conceptual design. The results show a better performance of 2D drawings, but support the complementary use of digital sculpting.

“…Finally, to achieve a more complete intent-driven design framework that better supports designer in the product shape manipulation, all these new modelling tools should be integrated in a unique feature-based modelling system, starting from the prototype developed in [3] and defining a completely new user interface naturally adhering the stylists way of working.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. ABSTRACTTo better simulate the way designers work, specific tools are needed to handle directly specific shape features meaningful for the design intent, without focusing on the underlying mathematic representation. For this purpose it is fundamental to identify proper higher-level shape descriptors as well as the corresponding manipulation techniques. The paper presents the definition and implementation of semantic operators for curve deformation based on a shape characterization that is specific to the industrial design context. The work grounds on the innovative approach suggested by the FIORES-II project for the intent-driven modeling tools for direct shape modification and on the multi-layered architecture proposed by the Network of Excellence AIM@SHAPE for the definition of semantic-oriented 3D models. In particular the paper proposes the use of meaningful aesthetic features for the evaluation of planar curve signature and for their intent-driven direct modification.
