Detailed Description

This class can be used to calculate the map projection (x, y) coordinates of the four corners of a cube from a set of arbitrary control points (ACP). The result is ordered according to the Petrel Ordered Corner Points (OCP) definition, which is as follows corresponding to bulk data access indices:

( 0, 0, ?) (size[0] - 1, 0, ?) ( 0, size[1] - 1, ?) (size[0] - 1, size[1] - 1, ?)
