M_SPHERE(3)	       FreeBSD Library Functions Manual		   M_SPHERE(3)

NAME
     M_Circle -- Agar-Math sphere structure

SYNOPSIS
     #include <agar/math.h>

DESCRIPTION
     The M_Sphere structure describes a	sphere in terms	of an origin point p
     and a radius r:

     typedef struct m_sphere {
	     M_Vector3 p;
	     M_Real r;
     } M_Sphere;

INITIALIZATION
     M_Sphere M_SphereFromPt(M_Vector p, M_Real	r)

     M_Sphere M_SphereRead(AG_DataSource *ds)

     void M_SphereWrite(AG_DataSource *ds, M_Sphere *S)

     M_Sphere M_SPHERE_INITIALIZER(M_Real x, M_Real y, M_Real z, M_Real	r)

     The M_SphereFromPt() function returns a M_Sphere describing a sphere of
     radius r centered at point	p.

     The M_SphereRead()	and M_SphereWrite() functions read or write a sphere
     structure from/to an AG_DataSource(3).

     The M_SPHERE_INITIALIZER()	macro expands to a static initializer for
     M_Sphere.

COMPUTATIONS
     M_Real M_SpherePointDistance(M_Sphere S, M_Vector3	p)

     M_Real M_SphereSurfaceArea(M_Sphere S)

     M_Real M_SphereVolume(M_Sphere S)

     The M_SpherePointDistance() routine computes the minimal distance between
     a sphere S	and a point p.

     M_SphereSurfaceArea() returns the surface area of the sphere.
     M_SphereVolume() returns the volume of the	interior of the	sphere.

HISTORY
     The M_Circle structure first appeared in Agar 1.3.4.
