THREE-g — galaxy primitives for playing with THREE.js

Generates a mesh of light spots in 3D space, extremely efficiently.

const m = massSpotMesh({
  spots: [...Array(4000)].map(() => ({
  x: Math.sqrt(Math.random()) * Math.sign(Math.random() - 0.5),
  y: Math.sqrt(Math.random()) * Math.sign(Math.random() - 0.5),
  z: Math.sqrt(Math.random()) * Math.sign(Math.random() - 0.5),
  mass: Math.random() * 0.01,
  rgb: new THREE.Color().setHSL(-Math.sqrt(Math.sqrt(Math.random())) + 1, 1, 0.3).getHex()
  }))
});

Mesh parameters

• spots particles that may have coordinates, colour and mass
• get if metrics of the spots are stored elsewhere, you can provide them via this callback
