## Detailed Description

Axis-aligned bounding box of signed integer coordinates.

Note
  The range of the integer coordinates, [min, max], is inclusive. Thus, a bounding box with min = max is not empty but rather encloses a single coordinate.

## ◆ Index64

typedef uint64_t Index64

## ◆ ValueType

typedef Coord::ValueType ValueType

## Constructor & Destructor Documentation

|  | ValueType | y_min,
|  | ValueType | z_min,
|  | ValueType | x_max,
