		const GLUSfloat	radius
	)

Copies a sphere.

Parameters

resultCenter	Destination center.
resultRadius	Destination radius.
center	Source center.
radius	Source radius.

GLUSAPI GLUSfloat GLUSAPIENTRY glusSphereDistancePoint4f	(	const GLUSfloat	center[4],
		const GLUSfloat	radius,
		const GLUSfloat	point[4]
	)

Calculates the signed distance from a sphere to a point.

If the value is negative, the point is inside the sphere.

Parameters

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