(5) 3-D views. The types of view discussed in chapter 7 can be very helpful in under-
standing a geological feature. If the feature is marked by high-amplitude events that
can be voxel-picked, it is easy to obtain a rapid first impression of its 3-D shape.
Where the seismic expression of the body is less obvious, it may be necessary to
