Reference · The <wakusei-space> element: the Earth, Moon, Sun and planets in their places

`WakuseiSpace`class

The <wakusei-space> custom element: the Earth, the Moon, the Sun and the planets where they are at a date and time, drawn with three.js through the shared renderer. It takes center ("lon,lat"), time (now or an ISO date), speed (1 is real time, 0 holds, 86400 is a day a second, negative runs backwards), scale (compressed or true), look (realistic or painted), light (sun or lit), lang (en or ja: the names), labels and orbits (off hides them), and texture-base, texture-far-base and max-texture. Positions come from this package's own models. It draws only when something changes, and nothing while it is out of sight.

It carries the shared view controls itself: a drag turns the camera round the body, two fingers pinch, Ctrl, Command or Alt with the wheel zooms (the plain wheel scrolls the page), and the arrow keys, + and - and 0 work once it is focused. controls="none" turns them off; zoom-min and zoom-max set the range (a millionth to 3 by default); a <kazoku-view-controls for="..."> takes over and reads it.

Members

Name	Type	Description
`controller`	`ViewController \| undefined`	The shared controller behind the element's own hands: for a page that moves the view itself, such as `controller.set({ zoom: space.zoomFor("moon") })`. It is there while the element is connected, whether `controls` is `none` or not.
`connectedCallback`	`(): void`
`disconnectedCallback`	`(): void`
`attributeChangedCallback`	`(name: string, _old: string \| null, value: string \| null): void`
`centre`	`{ lon: number; lat: number; }`	The home place the camera starts above, as longitude and latitude in degrees.
`time`	`number`	The moment shown: milliseconds since the epoch, or "now" to follow the clock. Setting it points the camera at the same place on the ground again.
`speed`	`number`	Seconds of game time per second: 1 is real time, 0 holds still, negative runs backwards.
`scale`	`ScaleMode`	`compressed` (the default: every direction real, the distances squeezed) or `true` (real distances and sizes).
`labels`	`boolean`
`orbits`	`boolean`
`look`	`"realistic" \| "painted"`	How the bodies are drawn: `realistic` (shaded from the body's real colours and features) or `painted` (public-domain surface maps).
`light`	`SpaceLight`	How the Earth is lit: `sun` (true, the default) or `lit` (as if by daylight from the camera's side, so the night side is never a black frame). The Sun, the Moon and the planets keep their true places.
`setView`	`(view: { yaw: number; tilt: number; zoom: number; }, final?: boolean): void`	The shared controls' camera: yaw and tilt turn the view (the Earth's surface moves right for a drag right and up for a drag up), zoom brings the camera in (1 shows the body looked at, less shows the sky round it). Pan is not used. A turn that moves nothing on the screen by half a pixel is kept for the next draw but does not cause one unless `final` is true (the default).
`body`	`"sun" \| "mercury" \| "venus" \| "earth" \| "mars" \| "jupiter" \| "saturn" \| "uranus" \| "neptune" \| "pluto" \| "moon"`	The body the camera looks at (`earth`, `sun`, `moon`, `mercury` to `neptune`, `pluto`): at zoom 1 it fills the view; the yaw and tilt turn the camera round it.
`bodyNames`	`Partial<Record<"sun" \| "mercury" \| "venus" \| "earth" \| "mars" \| "jupiter" \| "saturn" \| "uranus" \| "neptune" \| "pluto" \| "moon", string>>`	The words shown beside each body, for a page in another language (`{ mars: "火星" }`). A body left out keeps its name in the element's `lang`.
`bodyHint`	`string`	What a screen reader hears after a body's name: "choose to look at it" by default, or the page's own words.
`bodyInfo`	`(id: SpaceBody): BodyInfo`	The name, radius and distance from the Earth of a body now, for a page's own caption.
`ride`	`(target: RideTarget \| null, options?: RideOptions): void`	Ride along with a body, a moon or a moving point of your own. By default the camera sits at it and looks at the body it goes round, with the way it is going at the top of the picture, at its real place for the moment shown, so the ground slides beneath as it moves along its orbit. A drag looks about from there (a drag right turns the camera to its left and a drag up tips it towards the bottom of its picture, so the ground follows the pointer), the shared controls' zoom narrows the view. A body of the view (`"moon"`, `"mars"`) goes round the Earth; a moon (`"io"`) goes round its planet; a point of your own (`{ at(ms) }`, a satellite, a probe) goes round `around` (the Earth by default) and the element knows nothing of what it is. Another call switches smoothly; `null` stops. The draw rate follows how fast the picture moves, never more than 30 a second (one a second for a reader who asked for reduced motion), and nothing is drawn out of sight.
`riding`	`RideState \| null`	What the camera is riding along with now, or null.
`zoomFor`	`(preset: SpacePreset): number`	The zoom that shows a part of the sky: the Earth alone, the Moon's orbit, the Sun, the planets out to Mars, all of them, or a planet's nearer moons, at this scale and moment.
`stats`	`{ state: SpaceState; draws: number; contexts: number; canvas: { width: number; height: number; pixels: number; }; distance: number; assets: { entries: number; refs: number; }; time: number; lookups: number; camera: { position: [number, number, number]; fov: number; }; bodies: { look: string; painted: number; moons: number; held: number; }; ride: { riding: boolean; lost: boolean; gliding: boolean; }; }`	What the element is doing, for a page or a test.
