详细描述

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.

构造及析构函数说明

◆ Sphere() [1/2]

Sphere.Sphere ( )

Standard constructor - creates a unit sphere around the origin.

◆ Sphere() [2/2]

Sphere.Sphere	(	Vector3d	center,
		double	radius )

Constructor allowing arbitrary spheres.

参数

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

成员函数说明
