1. A method for displaying 3D seismic data comprising: accepting an indication of a first point in a 3D seismic data set; executing using a computer processor a seed picking algorithm, using the first point for picking a set of second points from the data set; setting using a computer processor each of the points in the set of second points as the first point and repeating the algorithm; assigning using a computer processor an iteration number to each of the second picked points, the iteration number corresponding to the number of algorithm executions needed to generate the picked point from the first point; and displaying information that represents the iteration number for each picked point.
