M_SPHERE(3) Library Functions Manual M_SPHERE(3) NAME M_Sphere -- Agar-Math sphere structure SYNOPSIS #include <agar/core.h> #include <agar/gui.h> #include <agar/math/m.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 be- tween 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.
