This paper describes methods and procedures for real-time rendering of high-resolution 3D stereoscopic graphics using an improved 3D OpenGL accelerator on PC platform. The hardware architecture and software development of the stereoscopic accelerator are first analyzed, followed by in deta...

The locomotion device is an input interface, which can sense the walking pace and direction of the user, for the virtual reality system. This paper presents a new type of locomotion device called Omni-direction Ballbearing Disc Platform(OBDP), which allows the user to walk&#...

Fractal image coding is a novel and attractive technique for still image compression. By utilizing the characteristic of self-similarity, an iterated function system can automatically converts an image into a set of affine transformation coefficients. However, the conventional block-based segmentation...

In the Mixed Reality environment that combines the real world and the virtual world it is important to control the ’place’ that comprises both real and virtual objects. In this paper, we study the overlay of humans and avatars in virtual space in the creation...

Professional educators cannot be isolated in their professions as simply conveyers of information who direct curriculum materials toward their students. The fact is that within our profession teaching very often occupies the smallest portion of our workday. In an effort to ...

The footwear industry’s need for an automatic containment algorithm is becoming increasingly important within the manufacturing process. Irregular containers, such as hides, have many different quality regions and holes that must be taken into account when containment is done because ...

The article offers a new approach towards the construction of recognition features independent of images’ displacement or linear deformation. The distinguishing characteristics of the group of features under study is representing each of them as a sequential composition of three funct...

The most important changes in cartography are associated with the development of computer technology (GIS), and regarding the function and usage of maps, the accent has been given to cartographic visualisation. The paper emphasises the need for closer collaboration of informatic ...

When movement of human is animated, motion information of each body part needs to be synchronized adequately in accordance with the motion type. In this paper, we propose an advanced method with the goal of technology supporting a more natural and intuitive interaction. ...

To support 3D architectural modeling, geometric constraints are introduced. Explicit and implicit geometric relations between building elements can be expressed by the designer and imposed on the 3D geometry of the design. A complete set of constraint types is defined. Constraints...

The most remarkable trends in communication have been the huge popularity of Internet and the growth of digital cellular telephony usage. There is a strong demand to combine these two in the form of mobile Internet access. This paper discusses the service implementation ...

In this paper, an immersive virtual environment is presented which allows the user to virtually explore and experience special relativity, including phenomena such as Lorentz contraction, time dilation, aberration, and finite speed of light. The relativistic-vehicle-control metaphor—a physically...
