map3d History and Concepts Rob MacLeod Bryan Worthen

map3d History 1990: First SGI, first GL, first map3d 1992/3: First papers: Visualization in Biomedical Computing 1992 IEEE Visualization Conference 1992 Visualizing Bioelectric Fields (Comp. Graphics and Appl.m 1993 IEEE EMBS Conference, 1993 1999: Started conversion to OpenGL 2000: First OpenGL release: Version 5.0 2003: March 2003, Version 5.4

Why map3d? Mapping: the driving application Graphics hardware and GL Spatiotemporal signals Electrophysiology of the heart Graphics hardware and GL Interactivity is essential GL is (was) simple

Goals of map3d Read Render Provide Surface based geometries Multichannel time signals Render Color coded maps of scalars Plots of time signals Provide Interactive control Interrogation of data Presentation graphics output

What Does map3d Need? Geometry Data Computer Surface or pseudo-surface Connectivity and facets Data Time signal for each point in geometry Computer SGI, Windows, Linux Mac/OSX coming soon
