TRIOLUME C3 — the third version: alpha, beta, C. C for arC. The 3 is the E. 1 + 1 = 2 = 3.

This is the free version. Every tool here is free and needs no login.

What is real, sample, or a stand-in

Real picture: the earth at night image (see img/LICENSE-three-globe.txt).
Stand-ins: the star field (decorative) and the town, where a town has no pack of real buildings.
Real towns: buildings © OpenStreetMap contributors (Open Database License 1.0), fetched 12 Nov 2026; the ground from USGS 3DEP elevation (public domain). Most heights are estimated from the number of floors or the kind of building; low water is read from the ground heights and is approximate; window lights at night are a pattern. Homes are never marked and no house is named. A town's pack loads only when its Town rung opens. Live towns (Settings, off by default) fetches buildings for a town with no pack from the Overpass API and needs a connection.
Photo-real cities: only in keyed builds, off by default, and only with the owner's own Google key and Google's yes. Drawn with 3DTilesRendererJS (Apache-2.0, California Institute of Technology) and Google's Photorealistic 3D Tiles, with Google's credits on screen while it shows. Never in an open site.
3D models and scans: drawn with three.js's own model loader. Its decoders (Draco and Basis Universal, Apache-2.0; meshoptimizer, MIT) are kept in this site and load only when a model opens. A model file or a scan you open stays on this device and is never uploaded. Each model's credit and license line shows under it.
The sky (looking up): star positions, names and constellation lines come from a published catalog (d3-celestial data, stars to magnitude 6; proper motions from the star-catalog-lite bright-star catalog). Positions of stars, the sun, the moon (and its phase) and the planets are computed with Astronomy Engine. We stand behind dates from 1600 to 2200, which is the range the bar accepts; the library is most precise from 1700 to 2200. Clock time is by the sun at each place (approximate); time zones are not used.

The free tools

Made on this device: every sound (piano, drums, metronome, tuner notes, the timer chime, Hear the sky) is made with the browser's own audio. No recordings.
Real and computed: the clock and calendar use this device's time. The compass works out the true starting direction and distance on the shortest path over the globe, from city-level places. Hear the sky uses the same computed sky as Look up.
Real, rounded: the sizes on the scale ruler are well-established and rounded; the shapes are simple drawings.
Kept on this device only: notes, tasks and calendar lines, if the browser allows saving. Nothing is sent anywhere.
Needs the internet: Weather (data from Open-Meteo.com, CC BY 4.0) and Radio (station list from the radio-browser.info open directory; each station plays from its own stream). Nothing is asked for until you open the tool.
Needs a sensor: the tuner and Say it use the microphone, live scanning uses the camera, compass heading and the level use the motion sensors. Each asks only when you tap it. The preview page blocks these; they work on triolume.com. Say it uses the browser's own speech-to-text, which in some browsers is done on the browser maker's servers.
Scan it: a photo you open stays on this device. A code that is a web link is shown as a link; it opens only if you choose it.
Never asked for: your location. Tools use the place already chosen or typed (Des Moines if none).
Player: plays files from this device (read by this browser only, never uploaded), secure addresses you paste (straight from where they live), and lists a vessel brings (only media the vessel owns; the demo sounds are tones made by the build). The list, the equalizer and a classic skin file are kept on this device only. A screen's address is typed in Settings (Screens in the house) and kept on this device; a box's password is never kept: it is asked for once per visit. Screens in the house work only when this site is opened from your home network or inside the Android app: browsers do not let a secure page talk to a plain box on a home network.
Player credits: sound visuals by Butterchurn (MIT, Jordan Berg) with presets from the butterchurn-presets pack (MIT; each preset by its own author); the classic windows by Webamp (MIT, Jordan Eldredge; its bundle includes React, Redux and JSZip, MIT), with a few on-screen words changed (see lib/webamp/CHANGES.txt). Their files and licenses are in lib/butterchurn, lib/butterchurn-presets and lib/webamp, and load only when the Player opens.

Settings and privacy

Motion, Glow, Units, Joins on the ring, Live towns and Screens in the house are in Settings (the button next to About). Forget this device there clears everything kept here, the Player's list and files, your models and scans included. Privacy: what stays on this device, and what is ever sent.
