Class: NullRenderer

Defined in: core/NullRenderer.ts:13

No-op renderer for headless mode. Drop-in replacement for Renderer that performs no actual rendering. Used when Scene is created with { headless: true } or via Scene.createHeadless().

  • render() and dispose() are no-ops; resize() updates in-memory dimensions
  • getCanvas() and getThreeRenderer() throw with descriptive errors
  • Width, height, colors are stored in memory for scene logic
