First Claim
1. A method for displaying 3D seismic data comprising:
- accepting an indication of a first point in a 3D seismic data set;
executing a seed picking algorithm, using the first point for picking a set of second points from the data set;
setting each of the points in the set of second points as the first point and repeating the algorithm; and
assigning an iteration number to each of the points, the iteration number corresponding to the number of times the algorithm repeated to process the point.

Abstract
A system and method may, based on a 3D seismic data set seed point, execute a seed picking algorithm, using the first point for picking a set of second points from the data set, setting each of the points in the set of second points as the first point and repeating the algorithm. An iteration number or other attribute may be assigned to the points, the iteration number corresponding to the number of times the algorithm repeated to process the point. The attribute or a number of attributes may be displayed as a visual characteristic for each point. An iterative process may be applied to a set of seismic data points, starting at a seed data point and finding a set of next iteration seed points from among the set of points neighboring the seed point, continuing only with next iteration seed points, and recording for each of a set of data points the number of points that are found by the process when the point is used as a seed data point. Attributes may include, for example, the total number of descendants of a seed point, the direction, for example, the azimuth, of propagation of the horizon picking process, or information that relates to the order in which points are picked such as an iteration number.
