Member Function Documentation

Intersect()

Circle Urho3D::Sphere::Intersect	(	const Sphere &	sphere,
		float *	distanceFromCenter = nullptr
	)		const

Intersect with another sphere. Return optional distance from the center of this sphere to intersection circle. If there's no intersection, return closest point to another sphere.
