Description

The Interval2d class corresponds to a bounding box in 2D space.

Interval2d and Interval3d are similar classes that keep an interval of values in 2D or 3D space, respectively. The classes were made to look uniform across 2 and 3 dimensions.

The bounds of the interval are accessed via public data members, lower and upper.

The interval classes contain operators and methods for extending or intersecting, as well as evaluating intervals.
