 John Belcher's POSTER from the AAPT Topical Workshop
Teaching General Relativity to Undergraduates
Held at Syracuse University, July 20-21, 2006

John Belcher

 Line integral convolution (LIC) is a technique introduced by Cabral and Leedom (1993) for visualizing the spatial structure of two dimensional vector fields at a resolution close to the resolution of the display.  Sundquist (2003) has developed a way to extend LIC visualization to time dependent vector fields (DLIC).  In particular, he has used the DLIC technique to make movies of electro-magnetic electric dipole radiation that show the details of the time dependent structure of that radiation in the near, intermediate, and far zone, at a resolution close to the resolution of the display.  Examples of these DLICs can be found on the web through links at  The purpose of this poster is to acquaint the GR community with the existence of this technique, to show examples of it, and to solicit input as to whether this technique can be used to visualize gravitational radiation.
