bool getIntersectionWithSphere	(	vector3d< T >	sorigin,
		T	sradius,
		f64 &	outdistance
	)			[inline]

Returns if the line intersects with a shpere

Parameters:

	sorigin,:	Origin of the shpere.
	sradius,:	Radius if the sphere.
	outdistance,:	Distance to the first intersection point

Returns:

Returns true if there is an intersection. If there is one, the distance to the first intersection point is stored in outdistance.
