3d Isovist Paper
I recently published a paper on 3d isovist analysis at the 2007 SIGraDi conference in Mexico. The illustrations are in greyscale and they screwed up some of the notation (basically, not rendering any sub- or super-scripts).
As the paper points out, this is not a configurational analysis or a complete one, but the fact that it uses a sample of the possible lines of sight allows it to run in polynomial time O(n2).
The paper can be downloaded here or read online using Issuu:
