If anyone is looking for the analysis of a regular subdivision
ray tracing method, see:
 journal:  Visual Computer July 1988
 title:    Analysis of an Algorithm for Fast Ray Tracing Using
           Uniform Space Subdivision
 authors:  Cleary, J and Wyvill, G
What the paper does is to describe the voxel traversal algorithm
that Cleary developed and that I use in my ray tracer, and then
a theoretical analysis is presented.  It is a convincing argument
for using regular voxel subdivision (although my method
- submitted to CGI '89 in UK - works better for scenes where
polygons are not evenly distributed throughout a scene).

Visual Computer is published by Springer Verlag.  Unfortunately
it doesn't enjoy the circulation of CG&A or TOG so it is
pretty (outrageously?) expensive (like $160 US for 6 issues!).

The design of our Mesh Machine is in:
  journal:  Proc CIPS Graphics Interface '83, 33-34, Edmonton, Alberta, May
  title:    Design and Analysis of a Parallel Ray Tracing Computer
  authors:  John Cleary and Brian Wyvill and Graham Birtwistle and Reddy Vatti

Anything else?
