Installation

$npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add life-ring

Copies safety/life-ring.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { LifeRing } from './components/deck-twin/safety/life-ring'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <LifeRing />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )

For agents

Machine-readable entry with props, ranges, defaults and ports:

$npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info life-ring

Or fetch /r/life-ring.json, or copy a ready-made instruction:

Add the Deck Twin "Lifebuoy station" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add life-ring` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info life-ring` for its props, ranges and ports. Render <LifeRing /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
