Three.js Cameras and Controls Guide

This guide explains camera configuration, control ergonomics, and common precision issues like z-fighting caused by poor near/far ranges.

Core Concepts

Camera configuration impacts both visual composition and numeric stability. Keep near/far clipping planes tight to reduce precision artifacts and use controls that match your interaction model.

const camera = new THREE.PerspectiveCamera(60, w / h, 0.1, 150)
const controls = new OrbitControls(camera, renderer.domElement)
controls.enableDamping = true

Best Practices

  • Keep scene setup, update loop, and cleanup code isolated for maintainability.
  • Prefer deterministic data flow and avoid hidden side effects in frame updates.
  • Profile changes on mobile-class hardware before shipping.
  • Document control schemes and provide readable non-canvas text context for SEO.
