ion allows natural language to 'directly' represent abstractions over experience in the AG domain. Such abstractions cannot be represented in analogue graphics. A simple example is that it is impossible to graphically represent colour in general. Because of their inherent specificity, analogue graphics have a limited potential for representing abstractions as compared to the corresponding natur...

Vegan Living is a visually appealing recent publication with creative colour graphics, engaging thought bubbles, and cameo statements that stimulate maintain interest. With extensive factual text including recipes guides it forms simple but vibrant explanation, based on compassion conviction, advocating personally chosen, adapted adopted vegan lifestyle.

A challenge in vector graphics is to define primitives that offer flexible manipulation of colour gradients. We propose a new primitive, called a shading curve, that supports explicit and local gradient control. This is achieved by associating shading profiles to each side of the curve. These shading profiles, which can be manually manipulated, represent the colour gradient out from their assoc...

This article deals with e-learning course of computer graphics that was created for distance, “face to face” and blended learning at the Department of Informatics, Faculty of Natural Sciences, Constantine the Philosopher University in Nitra, Slovak republic. The subject Computer Graphics is the part of bachelor study program of discipline Applied Informatics and is determined for students of ma...

A new test of colour vision using computer graphics has been used to obtain quantitative estimates of colour contrast sensitivity in ophthalmologists before and after they have treated patients by argon laser retinal photocoagulation. The colour vision of all subjects is normal when tested with the 100-hue test and HRR (Hardy, Rittler, Rand) plates, but colour contrast sensitivity measured alon...

Abstract We present recent results from an EPSRC funded project VirTex (Virtual Textile Catalogues). The goal of this project is to develop graphics and image-processing software for the capture, storage, search, retrieval and visualisation of 3D textile samples. The ultimate objective is to develop a webbased application that allows the user to search a database for suitable textiles and to vi...

Colour plays a central role in thematic cartography. Despite this, using colour effectively on maps is surprisingly difŽcult and often exceeds the skill and understanding of novice mapmakers. On the one hand, a ‘good’ colour scheme needs to be attractive. On the other hand, the colour scheme must also support the message of the map and be appropriately matched to the nature of the data. Moreove...

We describe a system for storing, transmitting and presenting digital lms in a computer network. The hardware used in the system is standard hardware, as found in typical workstations today; no special hardware is required. The movies are shown in a window of the X Window System. This allows full integration with the classical components of computer applications such as text, color graphics, me...
