BodyPaintertype

The seam for drawing the Sun, the planets and their moons. The space view places them, sizes them, lights them and labels them; a painter only makes what is drawn at each place. The default (plainPainter) is a sphere in the body's colour, and a glow for the Sun. Another package can supply better looking ones: @johnmorrisdotca/wakusei-planets/painter draws the real Sun, planets, Pluto and moons. make may return a drawing at once or later (a promise); a drawing may update itself and ask for a redraw when a picture arrives. moons is optional: the moons the painter can draw for a planet at a moment, which the view shows round the planet when it is near enough to see them. looks names what context.look may be.

import type { BodyPainter } from "@johnmorrisdotca/chikyu-earth/space";

interface BodyPainter {
    make(three: ThreeParts, name: string, context?: PaintContext): BodyDrawing | Promise<BodyDrawing>;
    moons?(planet: PlanetName, ms: number): readonly BodyMoon[];
    looks?: readonly string[];
}

import { plainPainter, type BodyPainter } from "@johnmorrisdotca/chikyu-earth/space";

const painter: BodyPainter = { make: (three, name) => plainPainter.make(three, name) };
console.log(typeof painter.make);
