KI Prototype
Interactive spherical-display prototypes for the research project
“행성지능 인터페이스를 위한 기후 빅데이터 구면 시각화 프로토타입 개발”.
Local development
npm install
npm run dev
Open http://localhost:3000.
Production
This repository is a standard Next.js application intended for Git-connected
Vercel deployments.
- Framework preset: Next.js
- Root directory:
.
- Build and install commands: use Vercel defaults
- Output directory: leave empty
- Node.js: 22.x
The main branch is the production branch. Other branches can be used for
Vercel Preview Deployments.
Data and media
ENSO data assets and the Daisy World video are served from public/projects.
The KAIST cafeteria route fetches current menu data at request time from the
official KAIST website.

Sampling Sphere
Static pages in public/sphere-*, built from sampling-sphere/studio-src.html and
sampling-sphere/data.js (20 satellite TLEs and one day of MODIS granule footprints):
python3 sampling-sphere/build.py
Display page. Stretches the frame to fill the whole screen (any size, e.g. 1920×1080).
Drag to rotate the sculpture, double-click to reset, press F for full screen. Move the
mouse to show the controls; they hide again after a few seconds.
Live control (studio → display and tablet).
- In
/sphere-studio, open Live control. It shows a room code and two links.
- Open the display link on the sphere computer and the tablet link on the tablet
(or open
/sphere-display / /sphere-tablet and type the room code into the box at the bottom right).
- Press Start live control. Every change in the studio (surface, frame, satellite, speed,
carving, light, material) appears on the other pages within a moment. A satellite picked
on the tablet also reaches the display. The display and tablet keep the last settings
if they reload.
It goes through a free public MQTT relay (wss://broker.emqx.io:8084/mqtt); only setting
values travel. The room code is not a password, so make a new one for each show. Another
relay can be used with ?broker=wss://....
URL settings for the display and tablet: ?room=CODE&style=afterglow|pixels|cut|build|erosion&ink=dark&frame=earth|sun|satellite&sat=TERRA&trail=6&depth=320&levels=even|orbit&speed=600&loop=1&quality=low. Afterglow (light that fades with the age of each observation) is the default surface; ink=dark draws it dark on light.
All pages share a clock (loop = days per loop), so separate devices show the same moment.
