TOWARDS VISUAL-BANDWIDTH: GETTING CLOSE TO ONE’S EXPERIMENT DATA
Mark R. Titchener · 2006
Abstract: This paper presents a novel general purpose visualisation environment SPOD (Space Odyssey), that has evolved in relation to our research needs involving analysis and measurement of chaos and complexity in time-series data. More specifically our attention has turned to deriving sleep state information from EEG/EOG. SPOD operates largely as an interpreter of formated data files, to display surfaces, static and/or animated line and point graphs, individually or simultaneously in a virtual 3-D viewing space. It comfortably handles sur-faces of more than 100,000 vertexes, and combinations of more than 15,000 static and/or animated graphs. User controls allow dynamic changes to viewing angle, lighting and display parameters. SPOD is ideally suited to ‘scoping ’ experiment data and results, for visually debugging complex processing algorithms, or simply providing visual insight into complex data sets. 1
