starPortrait関数

A star drawn from its numbers as SVG text: a disc in the colour of its temperature, darker toward the edge by its limb-darkening coefficient, with a generic surface texture of the right kind of cells for its type, and, for Altair and Regulus, the flattened and gravity-darkened shape that interferometers measured, and for Vega the round face of a star seen over its pole. The picture says, in its own words, that it is drawn from numbers and that the texture is generic. Nothing in it is a photograph or an artist's guess at one star's markings.
