Currently, I am working on sorting out the 3-D coordinate geometries of the data set to be able to do some pre-processing. The idea will be to develop some ``true'' 3-D preprocessing algorithms using the Connection Machine and/or the Cray YMP/8 and C90. I also insist that these processes be as true-amplitude as possible, because I am ultimately interested in preserving the raw AVO character in order to subsequently apply my prestack impedance inversion techniques.
