I have recently started a new business, which means I no longer have time to maintain this project.
Please reach out if you are interested in updating this component to the latest versions of aframe, merging the pending PRs, and resolving the list of issues ❤️
A 3D street map entity & component for A-Frame.
The <a-map> entity displays a plane textured with a rendered OpenStreetMap
map.
Use directly from the unpkg CDN:
<head>
<script src="https://aframe.io/releases/0.8.0/aframe.min.js"></script>
<script src="https://unpkg.com/aframe-map/dist/aframe-map.min.js"></script>
</head>
<body>
<a-scene>
<a-map position="0 0 -5"></a-map>
<a-camera></a-camera>
</a-scene>
</body>Install via npm:
npm install aframe-mapThen register and use.
import 'aframe';
import 'aframe-map';Note: The <a-map> entity automatically includes the
map component.
| attribute | type | default | description |
|---|---|---|---|
| pxToWorldRatio | number | 100 | The number of pixels per world unit to render the map on the plane. ie; when set to 100, will display 100 pixels per 1 meter in world space. (see a note on fidelity) |
| accessToken | string | An optional access token if using Mapbox's style. Not needed if you use your own styling | |
| style | string | '' | Either a Mapbox URL (like mapbox://styles/mapbox/...) or a JSON.stringify'd MapBox style. If none is provided, a default style will be loaded. (see creating a style) |
| ... | All other options are passed directly to Mapbox GL |
The higher pxToWorldRatio, the more map area will be displayed per world
unit. That canvas has to be translated into a plane in world space. This is
combined with the width and height in world space (from geometry.width and
geometry.height on the entity) to set up the plane for rendering in 3D.
The map is rendered as a texture on a 3D plane. For best performance, texture
sizes should be kept to powers of 2. Keeping this in mind, you should work to
ensure width * pxToWorldRatio and height * pxToWorldRatio are powers of 2.
MapBox styles are a JSON specification for how to render different layers of the map.
Creating new styles can be done by hand, or with an editor such as Maputnik. Take special note of the tile server to be used; Mapbox charges for access to theirs, however there is a free CDN powered by osm2vectortiles.org/ (this is the server used by the default style).
Note: The osm2vectortiles free CDN defaults to insecure http URLs which will be rejected by browsers on security grounds when the main site is served over secure https.
You can also easily host your own tile server!
