README 전문 보기 ↗A point-cloud visual piece for a 5:55 improvised piano solo by Incheol Kim.
A researcher stands alone on an alien world. Every note she hears goes out as a sonar pulse, and what it touches comes back as points of light: the sand at her feet, a broken stele with a worn handprint, the ruins of a city buried under a mound. Time drifts back and the city stands again; giant whale-like beings pass overhead, come close, and leave.
Watch it
The whole picture is generated in the browser from code and from timing data of the performance; nothing in it is pre-rendered.
| Input | Action |
|---|---|
| Tap / click, or Space | Play / pause |
| Double-tap the left / right third, or ← / → | 5 s back / forward (keep tapping to add 5 s) |
| Drag the bar on the pause screen | Jump |
Smooth playback needs a capable GPU. On laptops with two GPUs, browsers often run on the power-saving one: in Windows,
Settings → System → Display → Graphics, set your browser to High performance. chrome://gpu (or edge://gpu,
whale://gpu) shows which GPU is in use.
Open dist/echolocation.html in Chrome, Edge or another browser with WebGL2. dist/echolocation.mp3 must sit next to
it. Opening the file directly (file://) works; no server is needed.
Page options:
dist/echolocation.html#t=125 — a still frame of second 125?w=1920&h=1080 — render at a fixed size regardless of the window?gen=1 — compute the researcher's points at load time instead of using the baked copy (slower, same picture)Requirements: Python 3 and Node.js.
python tools/build.py # src/ + data/ -> dist/echolocation.html (bakes the researcher's points with tools/bake.js)
node --test "test/*.test.js"
python -m unittest discover -s tools -p "test_*.py"
data/music.json holds the note onsets, velocities and loudness envelope of the performance. It was made from the
original MIDI and WAV with tools/make_data.py; those originals are not part of this repository (the tests that need
them are skipped). To rebuild it, put them at media/echolocation.mid and media/echolocation.wav, or set ECHO_MIDI
and ECHO_WAV. The build copies media/echolocation.mp3 (or ECHO_MP3) into dist/ when present and keeps the
existing dist/echolocation.mp3 otherwise.
tools/export_video.mjs renders the 4K / 1080p 60 fps video in headless Microsoft Edge (Windows): every frame is the
average of 16 sub-frames over a 180° shutter with sub-pixel jitter, streamed into ffmpeg together with the original WAV.
It needs ffmpeg (tools/ffmpeg/bin/ffmpeg.exe or ECHO_FFMPEG) and the WAV (media/echolocation.wav or ECHO_WAV),
neither of which is included. The rendered videos are published on YouTube, not here.
The tools/check_*.mjs scripts are browser checks used during development (headless Edge).
