NR::Rect Class Reference

#include <nr-rect.h>

List of all members.

Detailed Description

A rectangle is always aligned to the X and Y axis. This means it can be defined using only 4 coordinates, and determining intersection is very efficient. The points inside a rectangle are min[dim] <= _pt[dim] <= max[dim]. Emptiness, however, is defined as having zero area, meaning an empty rectangle may still contain points. Infinities are also permitted.
