Detailed Description

A sphere primitive, mostly used for bounds checking.

Remarks

A sphere in math texts is normally represented by the function x^2 + y^2 + z^2 = r^2 (for sphere's centered on the origin). Ogre stores spheres simply as a center point and a radius.

Constructor & Destructor Documentation

Sphere() [1/2]

ParaEngine::Sphere::Sphere ( )

inline

Standard constructor - creates a unit sphere around the origin.

Sphere() [2/2]

ParaEngine::Sphere::Sphere ( const Vector3 &  center, float  radius  )

inline

Constructor allowing arbitrary spheres.

Parameters

center	The center point of the sphere.
radius	The radius of the sphere.
