ABSTRACT This paper introduces an immersive styling environment, which aims at closing the gap between 2D drawing and 3D modeling in the design process. The main goal of the styling system is to provide the user an easy to use interface hiding the inherent mathematic nature of CAD. Creating rough 3D sketches should literally be as intuitive as 2D sketching with pen and paper. To achieve this, the tools developed in our system benefit from the stylists' skills, acquired through training over time. This paper focuses on the stroke-input methods of our styling system. We present different techniques for creating and modifying 3D curves: stroke splitting, oversketching and taping. In addition we report on the viability of using input constraints in immersive environments to overcome inherent weaknesses.

    ABSTRACT: The renovation of the process represents a must for an industrial company involved in the design field. The process is moving from an entirely manual to a digital workflow, so much that sometimes users find many difficulties in the approach to the new tools. In particular, analyzing the methodologies of work it is easy to find out a big gap be-tween the styling phase and the creation of the 3D model. One question to investigate is how much the style of a model starts to be influenced by the technological tools designed to construct it. Starting from an accurate study of the Italdesign-Giugiaro process we present the efforts made to overcome the is-sues and define a more designer-oriented workflow, with the aim of the European Research Project SmartSketches. Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Computer Graphics]: Line and Curve Gen-eration).

    ABSTRACT: In the early stages of automotive design, designers produce a rich set of concept sketches to develop and communicate their ideas. These sketches convey useful information regarding the desired shape and style. However, creating a 3D digital model consistent with the sketch is a laborious process with existing CAD tools. This shortcoming limits most conceptual explorations to 2D, leaving the designer with little or no means to realize their ideas in 3D. To address this challenge, this work presents a new method that helps car designers transform their 2D concept sketches into 3D geometry using simple, interactive techniques. At the heart of our approach is an optimization-based shape deformation algorithm that takes as input a set of fiducial points marked by the user on the sketch. The proposed algorithm first aligns, and then deforms, an underlying template model until its fiducial nodes match those marked in the sketch. Next, the designer refines the template model by tracing the car’s key character lines on the sketch. Finally, using the newly shaped template model as a substrate, the designer can explore different styling ideas by sketching and modifying 3D curves directly on the template. We demonstrate the effectiveness of our approach on several examples.

    ABSTRACT: VR systems are well accepted in the product development process today. However this technology does not have a broad penetration and high number of installations in comparison to desktop systems, due to the high investments in VR technology especially hardware. On the user interface side many VR systems took over ideas from traditional WIMP interfaces (windows, icons, menus, pointers) without maintaining a smooth transition for the users from desktop environments to immersive environments and vice versa. In addition a great bunch of multi modal interaction techniques have been developed to render VR interaction more intuitively. This paper discusses various user interface concepts of VR systems and their use along the product development process. We give examples for solutions and projects developed in collaboration with different companies, such as BMW, Italdesign, FIAT, Airbus.
