SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Sync DOM-based UI outside the Canvas with updates from the render loop, enabling real-time HUDs and overlays without embedding UI in the 3D scene.

Core Features & Use Cases

  • External useFrame: run outside the Canvas to update DOM elements in sync with 3D.
  • Ref-based DOM updates: manipulate DOM nodes directly for performance.
  • Throttling: optionally throttle updates with the fps option to reduce DOM work.
  • Use Cases: HUDs, debug panels, and UI that doesn't require 3D space.

Quick Start

Create a UI component outside the Canvas and update its DOM content on every frame with useFrame.

FAQPage Schema
How do I sync DOM UI elements with the React Three Fiber render loop?

To sync DOM UI with the render loop, use R3F v10's useFrame outside the Canvas to manipulate DOM nodes directly via refs, enabling real-time updates for overlays like HUDs without embedding UI in the 3D scene.

Can I update a React HUD outside the Canvas using useFrame?

Yes, you can update a React HUD outside the Canvas using useFrame by attaching refs to your DOM elements and mutating them directly during the render loop, which avoids React reconciliation overhead for frequent visual updates.

How do I throttle DOM updates in React Three Fiber to improve performance?

You can throttle DOM updates in React Three Fiber by utilizing the fps option within useFrame, which reduces the frequency of DOM mutations to lower browser reflow work while maintaining acceptable visual synchronization.

Do I need to embed UI elements inside the 3D scene to track object positions in R3F?

No, you do not need to embed UI elements inside the 3D scene. You can render standard DOM UI externally and sync it with 3D scene updates using useFrame and DOM refs, which is ideal for debug panels and HUDs.

What are the requirements for syncing external UI with React Three Fiber v10?

Syncing external UI with React Three Fiber v10 requires React, R3F version 10, and DOM element refs to directly manipulate nodes, along with the optional fps option if you need to throttle update frequencies.
