The point carries (x,y), a central angle α₀, a tighter bending band ±β, and a normal right-angle anchor taken from the perpendicular ray.

Drag the bright point to change (x,y). Drag the golden handle to rotate the central angle α₀. The dotted arc shows the allowed α band. The violet point is the nearest finite anchor of the normal ray at angle α + π/2.
