Andrew,
The following is a link to the Center for the computation and Visualization of Geometric Structures at the University of Minnesota.  A treasure trove of information and even downloadable software.

Do you know of any good web sites covering
computational geometry / GIS algorithms. I am
interested in polygon/polygon intersection and
buffering but not circular buffering i.e. if you have
a polygon I need an algorithm that creates a buffer of
equal size all round the polygon so that the buffer
mimicks the shape of the polygon.
 
regards,
andrew bailey
