In 1985, Joseph O'Rourke published a cubic-time algorithm to find the minimum-volume enclosing box of a 3-dimensional point set. O'Rourke's approach uses a 3-dimensional rotating calipers technique, and is based on lemmas characterizing the minimum enclosing box: • There must exist two neighbouring faces of the smallest-volume enclosing box which both contain an edge of the convex hull of the point set. This criterion is satisfied by a single convex h… WebChoose a side of the box and project both the point and the box to the line to which that side belongs. Then check if the projected point is inside the projected box as you would do it with an axis if you were checking against an axis-aligned bounding box. Then choose a side perpendicular to the one you just checked against and run the same test.
