# WebGL and React Integration

## Summary
Manage WebGL contexts and 3D scenes declaratively using React reconciliation.

## Key Capabilities
- Map React props to WebGL uniform updates.
- Manage canvas resize and context loss events.
- Integrate DOM overlays with 3D scene coordinates.

## PhD-Level Challenges
- Bridge the imperative render loop with React's scheduler.
- Optimize object creation/destruction for garbage collection.
- Implement raycasting for interaction events.

## Acceptance Criteria
- Render a 3D scene driven by React state.
- Demonstrate performant frame updates (60fps).
- Implement mouse interaction with 3D objects.

Overview

This skill manages WebGL contexts and 3D scenes declaratively by using React reconciliation to drive rendering state. It presents a pattern that maps React props to GPU uniforms, handles canvas lifecycle events, and keeps DOM overlays aligned with scene coordinates. The goal is predictable WebGL scenes controlled by React state while maintaining high-performance frame updates and interactions.

How this skill works

The integration maps React component props to WebGL uniform updates and material parameters on every render cycle. A reconciler coordinates creation and disposal of GPU resources, listens for canvas resize and context loss, and schedules imperative render loops alongside React's scheduler. Interaction is implemented via raycasting: screen events are projected into scene space and routed to React handlers.

When to use it

  • You need declarative control of a 3D scene from React state and props.
  • You must synchronize DOM overlays (UI labels, tooltips) with 3D coordinates.
  • You require predictable resource management and graceful context loss handling.
  • You want to implement interactive 3D UIs driven by React event handlers.
  • You need to optimize creation/destruction patterns for long-running apps.

Best practices

  • Batch uniform and property updates in reconciliation cycles to minimize GL calls.
  • Keep per-frame work minimal: update only changed objects and use instance rendering where possible.
  • Handle canvas resize and devicePixelRatio changes to maintain crisp rendering.
  • Debounce expensive React state updates that trigger heavy GPU allocations.
  • Implement explicit resource pooling and dispose patterns to avoid GC spikes.

Example use cases

  • A visualization dashboard where React controls 3D chart parameters and annotations.
  • An editor that overlays HTML controls over objects in a WebGL scene for precise manipulation.
  • A product configurator where property panels update materials and lighting in real time.
  • A simulation UI that needs stable 60fps rendering while React updates parameters and telemetry.

FAQ

How do I keep 60fps when React state changes frequently?

Minimize per-frame allocations, batch updates, use requestAnimationFrame for render ticks, and move non-essential updates off the main loop or debounce them.

How is interaction handled between DOM events and 3D objects?

Screen coordinates are unprojected into scene space and raycasting determines intersections, then mapped to React event handlers on the corresponding components.

What happens when the WebGL context is lost?

The skill listens for context loss events, pauses rendering, and either attempts context restoration or recreates GPU resources via the reconciliation layer.
