=head1 NAME

BH_Box2f - two-dimensional bounding box


=head1 SYNTAX

 #include <BH/Math/Box2f.h>

 cc prog.c -o prog -lbh


=head1 DESCRIPTION

The BH_Box2f module provides functions for working with two-dimensional bounding
boxes. It includes operations for union, intersection, checking if a point is
inside a rectangle, and calculating the bounding box for a set of points.


=head1 API CALLS


=head2 BH_Box2fUnion

 void BH_Box2fUnion(const float aMin[2],
                    const float aMax[2],
                    const float bMin[2],
                    const float bMax[2],
                    float outMin[2],
                    float outMax[2]);

Combines two bounding boxes A and B.

The parameters I<aMin> and I<aMax> describe the bounding box A.

The parameters I<bMin> and I<bMax> describe the bounding box B.

The parameters I<outMin> and I<outMax> describe the resulting bounding box.


=head2 BH_Box2fIntersect

 int BH_Box2fIntersect(const float aMin[2],
                       const float aMax[2],
                       const float bMin[2],
                       const float bMax[2],
                       float outMin[2],
                       float outMax[2]);

Calculates the intersection of two bounding boxes A and B.

The parameters I<aMin> and I<aMax> describe the bounding box A.

The parameters I<bMin> and I<bMax> describe the bounding box B.

The parameters I<outMin> and I<outMax> describe the resulting bounding box.

Returns 0 in case of successful intersection or an error code.


=head2 BH_Box2fContains

 int BH_Box2fContains(const float aMin[2],
                      const float aMax[2],
                      const float point[2]);

Checks if the point is inside the bounding box.

The parameters I<aMin> and I<aMax> describe the bounding box.

The parameter I<point> describes the point.

Returns 0 if the point is inside the rectangle, or an error code.


=head2 BH_Box2fEnclose

 int BH_Box2fEnclose(const float *points,
                     size_t size,
                     float outMin[2],
                     float outMax[2]);

Calculates the bounding box for the given points.

The parameters I<points> and I<size> describe the input array of points.

The parameters I<outMin> and I<outMax> describe the resulting bounding box.

Returns 0 in case of successful calculation or an error code.
