    Advantages of allowing Hexagonal Pixels to be used as a Boundary Description Format
    (The Eurographics Association, 2007) Turner, Martin J.; Ik Soo Lim and David Duce
    This paper considers some algorithmic extensions and some specific advantages when using a hexagonal pixel array as compared with the usual practice of using a rectangular or square pixel raster array. Discussed are some of the algorithmic changes that are required when using pixels arranged within a hexagonal matrix. The use of a boundary hexagonal description format is considered from the point of view of; hexagonal six-connected contour edge encoding as compared with square four-connected and eight-connected descriptors, efficient probability autocorrelation analysis, direct image manipulation and algorithmic simplification. Hardware and software conversion techniques for hexagonal pixels are now being seriously considered especially with the potential emergence of hexagonal CCD censor arrangements for cameras; for example this includes a recent patent with Fuji Photo Film Co.Ltd. (US patent number 6882364 Apr 19 2005) incorporating a bidirectional honeycomb pattern.

    Streaming and Data Enrichment
    (The Eurographics Association, 2007) McDerby, Mary J.; Hewitt, William T.; Turner, Martin J.; Ik Soo Lim and David Duce
    Data is being created at a continuously increasing rate. Scientists are drowning in their data . So much so they cannot visualize the data to see the big picture. This work-in-progress paper describes a data capture and visualization problem, and the steps being undertaken to solve the problem. An overview is given of the various approaches to dealing with these large data sets that have been previously proposed and the application of such methods within a well known scientific visualization tool. The paper then goes on to propose a method that deals with large data visualization by addressing the bottlenecks in the visualization pipeline, and combining some of the approaches described herein with parallel techniques on a high performance visualization system.
