    The view that visual reasoning in design is facilitated by external visualisation, specifically sketching, is based on both anecdotal evidence and empirical observations. The purpose of the current research is to investigate the relationship between visual reasoning, via sketches and the development of the early conceptual stages of the design process. Thus, the paper focuses on an analysis of vis... View full abstract»

    This paper presents a technique for representing animal models in terms of a set of axial curves. An object or an animal model is defined as the union of a set of different parts. Each part of the object is represented in an axial space defined by an axial curve-pair-a primary curve and an orientation curve. A hierarchy of axial curve-pairs defines the relative positions and orientations of differ... View full abstract»

    Design process planning is essential for business success. However, it is complex for all but the simplest products. There is therefore a need for effective support for the design process planner to help them visualize and assess alternative design process strategies. The paper describes a new approach to design process planning, known as signposting, which has the potential to assist in the chara... View full abstract»

    In this work, we propose the ZF-buffer algorithm in order to accelerate the intersection test of ray tracing. The ZF-buffer is used in the preprocessing of ray tracing and records the pointer that points to a parent face of a depth value (z value) of an object determined in the Z-buffer. As a result, the face that intersects with the first ray can be determined easily by using the pointer stored i... View full abstract»

    Modeling fur and hair remains one of the hottest subjects in modern computer graphics. Although some promising techniques to model and render furry and hairy objects were developed in the recent past, and several commercial packages are available, the problem still remains very challenging. The article presents a fresh practical technique to model and render fur and hairs, that is applicable for a... View full abstract»

    Muscle simulation should be an important component of human modelling, but to date there have been few attempts to demonstrate muscle structures in an anatomically-correct way. This paper proposes a feature-based approach to muscle modelling which attempts to provide models for human musculature based on the real anatomical structures. These models provide a good visual description and form a soun... View full abstract»

    Synthesis of hair images is one of the most important and challenging computer graphics problems. We propose a new technique for automatically generating realistic human hair texture on 3D models of human characters. The idea is inspired by the similarity between the texture of human hair and the texture generated by the LIC algorithm. The proposed technique generates the texture of human hair usi...

    Traditional searching and browsing functions for bibliographic databases no longer enable researchers to deal efficiently with the rapidly growing number of scientific publications. Our project BibRelEx aggregates expert knowledge on a body of scientific literature and makes it available to researchers who wish to explore the literature. We take a two-pronged approach. First, we collect expert ann... View full abstract»

    This paper introduces an optimal hierarchical adaptive mesh construction algorithm using the face-centered orthorhombic lattice (FCO) sampling which is a natural extension of the quincunx lattice to the 3-dimensional case. A scheme for construction of adaptive meshes is presented. Initially, a highly detailed and densely sampled regular mesh is obtained from geometry scanning or from a nonoptimal ...

    Multi-user VR systems are mostly aimed at social interaction, whereas exploitation of shared virtual environments for educational purposes has been largely ignored. We introduce the notion of tutor-based systems and consider the main differences between a tutor-based multi-user system and a social interaction system. In the proposed approach, one of the users is the tutor while the others represen... View full abstract»

    A rational cubic C2 spline curve is described which has interval and point tension weights for manipulating the shape of the curve. The spline is presented in a local support basis form, and the effect of the weights on these representations is analysed. Subsequently this work has been extended for the modelling of interpolatory curves through B-spline formulation View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (456 KB)

    Based on the analogy of architectural composition as a formal language, a form processor is developed and tested. The proposed processor addresses a universal language of architectural form. It aims to facilitate the manipulation of forms in a manner similar to that in which a word processor manipulates words in natural languages. Based on the ontological assumption of structuralism, epistemologic... View full abstract»

    The necessity of applying image processing techniques to gel electrophoresis images is starting to appear. In particular, registering two gels for comparison purposes has emerged from the increasing popularity of gel databases distributed across the Internet. Current registration techniques are however cumbersome in the sense that they require user intervention for placing landmarks on both gels i... View full abstract»

    Annotating photographs is such a time-consuming, tedious and error-prone data entry task that it discourages most owners of personal photo libraries. By allowing the user to drag labels, such as personal names, from a scrolling list and drop them onto a photo, we believe we can make the task faster, easier and more appealing. Since the names are entered in a database, searching for all photos of a... View full abstract»

    One of the main aspects of the Internet is that it is a distributed, multimedia database offering a fast growing amount of valuable information. Searching this database can be done by posing questions to search machines like Alta Vista. On the other hand, it is possible to browse through the space of connected information objects. When browsing, the problem arises that the user usually has no spec... View full abstract»
