- ItemOpen AccessConsidering Visual Variables as a Basis for Information Visualisation(2003-01-30) Carpendale, M. S. T.The purpose of this report is to discuss Bertin's concepts about visual variables [Bertin 67/83], which are no longer readily available since they are out of print. Bertin introduced the idea of visual variables as part of his extensive analysis of cartography in the creation of what he terms data graphics as part of his Semiology of Graphics [Bertin 67/83]. In this report these concepts are discussed in terms of computational information visualisation instead of printed cartography. The discussion will centre on how these visual variables can be used in the creation of visual representations for the purpose of informaion visualisation.
- ItemOpen AccessEXPANDING THE EXPRESSIVE PALETTE(2001-05-30) Mason, K.; Carpendale, M. S. T.Current methods in non-photorealistic graphics can place a heavy amount of focus on the algorithm, as opposed to the artist. In this paper, we analyze these trends, and present a conceptual framework for putting control back in the hands of the artist. Combining ideas from non-photorealistic graphics and artificial intelligence, we present new methods of supporting alternative artistic styles. Details of our implementation of this model are described, as well as methods for interaction. Finally, we create a simulation under this framework, and show preliminary results.
