A system and method is provided for analyzing and imaging
three-dimensional volume data sets. In one embodiment of the invention, a
ribbon section is produced which may include a plurality of planes
projected from a polyline. The polyline may include one or more line
segments preferably formed within a plane. The projected planes intersect
the three-dimensional volume data set and the data located at the
intersection may be selectively viewed. The polyline may be edited or
varied by editing or varying the control points which define the
polyline. In another embodiment of the present invention, a method is
provided for quickly tracking a physical phenomena represented within the
three-dimensional volume data set. A plurality of planes may be
successively displayed in the three-dimensional volume data set from
which points are digitized related to the structure of interest to create
a spline curve on each plane. The area between the spline curves is
interpolated to produce a surface representative of the structure of
interest, which may for example be a fault plane described by the
three-dimensional volume data set. In this manner, the user can more
easily and effectively visualize and interpret the features and physical
parameters that are inherent in the three-dimensional volume data set.
