Part assembly and scene layout are basic tasks in 3D design in Desktop Virtual Environment (DVE) systems as well as Computer Aided Design (CAD) systems. 2D input devices such as a mouse or a stylus are still the most common input devices for such systems. With such devices, a notably difficult problem is to provide an efficient and predictable object motion(More)
Conceptual design dominates the early stages of most creative design processes. During these stages, the designer makes important decisions about the parameters of a model that are aimed at satisfying a set of design criteria. To do this, the designer produces many sketches of various possible solutions. Meanwhile, computer-aided design (CAD) systems are(More)
Neutrophil apoptosis is a constitutive process that can be enhanced or delayed by signals triggered by various stimuli. In this work, we investigated the action mechanism of phospholipase D (PLD) and its expression in the inhibition of spontaneous and Fas-mediated apoptosis. Anti-Fas antibody-stimulated apoptosis of neutrophils was significantly blocked by(More)
Object selection and manipulation (e.g. moving, rotating) are the most basic tasks in 3D scene construction. While most research on selection and manipulation techniques targets single objects, we examine the concept of group selection in this paper. Group selection is often given lesser importance than single object selection, yet is vital in providing(More)
Many important decisions in the design process are made during fairly early on, after designers have presented initial concepts. In many domains, these concepts are already realized as 3D digital models. Then, in a meeting, the stakeholders for the project get together and evaluate these potential solutions. Frequently, the participants in this meeting want(More)
In the early stages of design, several concepts are usually generated to explore the possibilities. This paper investigates how well a computer-based system can support design thinking. SESAME is a novel 3D design system that aims to support creativity during the explorative phase of the design process. We report an evaluation comparing SESAME to paper(More)
