double AMP::Geometry::Sphere::distance	(	const Point &	pos,
		const Point &	dir
	)		const

finaloverridevirtual

Calculate the distance to the object given a ray.

This function computes the distance to the object given a ray. If the ray is inside the object, this distance is negitive. If the ray will never intersect the object, this distance is inf.

Parameters

[in]	dir	Direction of ray (should be normalized for most uses)

Returns: Returns the distance to the nearest surface (intersection = pos + dir*distance)

Implements AMP::Geometry::Geometry.
