1. map3d History and Concepts
Rob MacLeod Bryan Worthen

2. 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

3. 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

4. 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

5. 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
