We present a system for sketching in 3D, which strives to preserve the degree of expression, imagination, and simplicity of use achieved by 2D drawing. Our system directly uses user-drawn strokes to infer the sketches representing the same scene from different viewpoints, rather than attempting to reconstruct a 3D model. This is achieved by interpreting strokes as indications of a local surface...

The Shape Calculus is a bio-inspired calculus for describing 3Dshapes moving in a space. A shape forms a 3D process when combinedwith a behaviour. Behaviours are specified with a timed CCS-like pro-cess algebra using a notion of channel that models naturally bindingsites on the surface of shapes. Processes can represent molecules orother mobile objects and can be part of net...

Motivated by the need for fast, accurate, and high-resolution approach to document heritage and archaeological sites before they are removed or destroyed, the goal of this paper is to develop and demonstrate advanced image-based techniques to capture the fine 3D geometric details of such sites. The size of the site can be large and of any arbitrary shape which presents a challenge to all existi...

Based on the .NET Framework 2.0, the new generation of the windows software development framework .NET Framework 3.0 has four new components, in which the most attractive one is WPF(Windows Presentation Foundation). WPF is a new GUI engine that can provide uniform descriptions and methods for user interface, 2D/3D graphic, document and media. In WPF, the commonly used rotation transformation me...

Mobile devices displaying 2D map representations are already commonly used for the exploration of urban surroundings on the move. Even though mobile detailed 3D visualizations promise to be an attractive way to cope with the increasing amount of georeferenced information, their widespread use is hampered by the fragmentation of today’s mobile device landscape. In this paper, we tackle this real...

Modern Land Mobile Radio has the potential for large growth in the near future. Current regulations have set the stage for a required transition to more spectrally efficient technologies. While several organizations are working to ease this transition, there still remain many details and feature sets which the end user must decide amongst and often there is no clear dividing line between these ...

With the advent of new game controllers, traditional input mechanisms for games have changed to include gestural interfaces and camera recognition techniques, which are being further explored with the likes of Sony’s PlayStation Move and Microsoft’s Kinect. Soon these techniques will include affective input to control game interaction and mechanics. Thus, it is important to explore which game d...
