Abstract:
This paper presents a novel general purpose visualisation environment SP OD (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. SP OD 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 surfaces 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. SP OD is ideally suited to ‘scoping’ experiment data and results, for visually debugging complex processing algorithms, or simply providing visual insight into complex data sets.
