From the Editors: Collaborative Computing Community--Leveraging Single-User Applications for Multiuser Distributed Collaboration Haifeng Shen, Nanyang Technological University, Singapore Chengzheng Sun, Nanyang Technological University, Singapore Single-user interactive computer applications are pervasive in our work and daily lives. Commonly used single-user interactive applications include te...

Generation of animated human figures especially in crowd scenes has many applications in such domains as the special effects industry, computer games or for the simulation of the evacuation from crowded areas. Currently such scenes have to be created by human animators using dedicated software packages. This is both expensive and time-consuming. Our “FreeWill” prototype proposes and implements ...

We present the methods that were used in capturing a library of human movements for use in computer-animated displays of human movement. The library is an attempt to systematically tap into and represent the wide range of personal properties, such as identity, gender, and emotion, that are available in a person's movements. The movements from a total of 30 nonprofessional actors (15 of them fem...

The Michelangelo project at the University of Glasgow has developed an experimental three-dimensional television studio. This uses 24 video cameras and parallel computers to capture moving three-dimensional models of human actors. This allows the capture in real time of the appearance and three-dimensional positions of a human actor. It does this using stereo imaging techniques that have been u...

We de ne a true 3D lm as a lm that can be viewed from any point in space. In order to generate true 3D lms, the 3D-MATIC Research Laboratory of the University of Glasgow has been developing a capture 3D studio based on photogrammetry technology. The idea is simply to generate 25 photo-realistic 3D models of a scene per second of lm. After the presentation of the state of the art in the domain, ...

Although techniques of computer graphics have evolved a lot during the last years, there are still genres of computer games that rely on 2D graphics, especially point-and-click adventures. Still, 3D elements can significantly improve appearance and development of 2D adventures. This work focuses on the integration of 3D characters into 2D environments as well as techniques of computer graphics ...

Recently, Virtual Environments (VE) are increasingly used as settings for design and research. Using VE to visualize ideas from the initial steps of design, the architect is challenged to deal with perception of space, solid and void, without translations to and from a two dimensional media. The goal of our studies was to identify how designers use and communicate early design ideas by using im...

Peyer's patches (PPs) are typical gut-associated lymphoid tissues that are located along the wall of the small intestine and that serve as the major sites for generation of immunity to intestinal antigens. Their unique micro-organization is crucial for the generation of the immune response. Although many studies have been reported on the functional anatomy of PP, most investigations have relied...

At 3DV Systems Ltd. we developed and built a true 3D video camera (Zcam), capable of producing RGB and D signals where D stands for distance or depth to each pixel. The new RGBD camera makes it possible to do away with color based background substitution known as chroma-key as well as creating a whole gallery of new effects and applications such as multilayer foreground as well as background su...
