Determines if ray intersects sphere.

  public Sphere(Point center,
                float radius,
                Pigment pigment,
                Finish finish)

  public boolean intersect(IntersectionRay ray)

Determines if ray intersects sphere. If it does, checks that point of intersection is closer to origin of ray than any previous point of intersection. If it is closer, returns true, if not, returns false.

Parameters:

ray - Ray to be tested for intersection.

Returns:

true If ray intersects disc and is closer to origin than any previous point of intersection, false otherwise.

Overrides:

Given a world description and the ray that intersects the sphere, returns the color of the sphere at the point of intersection.

Parameters:

world - The world containing the sphere.
