A Moore curve after E. H. Moore is a Geometric continuity continuous fractal space filling curve space filling curve which is a variant of the Hilbert curve . Precisely, it is the curve definitions loop version of the Hilbert curve, and it may be thought as the union of four copies of the Hilbert curves combined in such a way to make the endpoints coincide. Because the Moore curve is plane filling, its Hausdorff dimension is 2. The following figure shows the initial stages of the Moore curve.

Other uses Vertex disambiguation Image Ellipse evolute.svg right thumb 240px An ellipse red and its evolute blue . The dots are the vertices of the curve, each corresponding to a cusp on the evolute. In the geometry of curve s a vertex is a point of where the first derivative of curvature is zero. This is typically a local Maxima and minima maximum or minimum of curvature. Other special cases may occur, for instance when the second derivative is also zero, or when the curvature is constant. For a circle which has constant curvature, every point is a vertex. The four vertex theorem states that every closed curve must have at least four vertices. Vertices are points where the curve has Contact mathematics Contact between curves 4 point contact with the osculating circle at that point. The evolute of a curve will have a cusp singularity cusp when the curve has a vertex. The symmetry set has endpoints at the cusps corresponding to the vertices, and the medial axis , a subset of the symmetry set also has its endpoints in the cusps. If a curve is reflection symmetry bilaterally symmetric , it will have a vertex at the point or points where the axis of symmetry crosses the curve. Thus, the notion of a vertex for a curve is closely related to that of an vertex optics optical vertex , the point where an optical axis crosses a Lens optics lens surface.
