Let's take our example a step further. Think of a 3-D seismic data set as a box full of numbers, each number representing a measurement (amplitude, for example). Each number has an (''x, y, z'') position in the box. For any point in the middle of the box, three planes pass through it parallel to the top, front, and side of the box.
