You can describe the binary SEGY file using the Data Prompter. Below is an
example of the general array description for a 3D survey with 74 inlines,
82 crosslines, 3 seconds of data at 2 ms. Note I included the 240 byte
trace header that is why there are 1560 z values. Sometimes there is a
3200(?) byte survey header that you can skip (add header = bytes 3200).
Jeff
file = 3dmig.clean
grid = 74 x 82 x 1560
format = msb binary
interleaving = record
majority = row
field = field0
structure = scalar
type = float
dependency = positions
positions = regular, regular, regular, 0, 1, 0, 1, 0, -0.05
end

I am trying to visualize 3D seismic data volume, met difficult when import
data. John Harris suggested using Segy2ascii to convert segy files, but
the ASCII file is too big. Maybe ¡°just write a description of position
array in dx format and import the data¡± is better. (Paul Huang, Oct 1999)
Anyone has got a simple way?
Thanks,
