Bounding Boxes (IM: QD3D)

Bounding Boxes
A bounding box is a rectangular box, aligned with the coordinate axes, that completely encloses an object. A bounding box is defined by the TQ3BoundingBox data type.
typedef struct TQ3BoundingBox {
   TQ3Point3D                 min;
   TQ3Point3D                 max;
   TQ3Boolean                 isEmpty;
} TQ3BoundingBox;
Field Description

min
The lower-left corner of the bounding box.
max
The upper-right corner of the bounding box.
isEmpty
A Boolean value that specifies whether the bounding box is empty (kQ3True) or not (kQ3False). If this field contains the value kQ3True, the other field of this structure are invalid.
