bool LitScene::intersect	(	GObject *	me,

		Colour &	colour,
		int	depth
	)

returns true if the ray intersects the scene, and if so then the colour at the intersection point. This overrides the method in Scene

Your code here (2) - do a recursive ray trace. Use specular colour to modulate the colour returned by the recursive intersect call

GObject * LitScene::intersect	(	Ray	ray,
		Point &	p,
		Vector &	n
	)

GObject * LitScene::isShadowed	(	GObject *	me,
