SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers achieve deterministic, frame-accurate rendering for Three.js scenes by syncing Helios ticks with 3D updates in both React Three Fiber and vanilla Three.js workflows.

Core Features & Use Cases

  • Deterministic frame-driven rendering: Drive 3D animations with Helios ticks instead of relying on the library's internal loop.
  • React Three Fiber integration: Subscribe to Helios to advance scene state in sync with Helios frames.
  • Vanilla Three.js workflows: Use Helios to drive updates and manually render each frame for precise timing.

Quick Start

Configure Helios in your project and wire a subscription that advances your 3D scene per Helios frame. Disable automatic frameloop and drive updates with the Helios tick stream.

FAQPage Schema
How do I achieve deterministic rendering in Three.js?

Deterministic rendering in Three.js is achieved by syncing Helios ticks with 3D scene updates instead of relying on internal loops. This ensures frame-accurate visual output by advancing state strictly per Helios frame.

Can I sync Helios ticks with React Three Fiber?

Yes, Helios ticks sync with React Three Fiber by subscribing to Helios to advance scene state. You must disable the automatic frameloop to ensure updates occur strictly in sync with Helios frames.

What is frame-accurate 3D timing and when do I need it?

Frame-accurate 3D timing synchronizes visual updates precisely to an external tick stream rather than browser refresh rates. It is needed when deterministic, reproducible scene playback is required for WebGL applications.

How do I use Helios to drive vanilla Three.js workflows?

To use Helios with vanilla Three.js, configure Helios in your project and wire a subscription that drives updates per tick. Manually render each frame to maintain precise timing control over the 3D scene.

Why are my React Three Fiber animations out of sync?

React Three Fiber animations fall out of sync when relying on the internal frameloop. Disable automatic frameloop and drive updates using a Helios tick stream to achieve deterministic frame synchronization.
