ThreeJS Performance Monitoring Tools for Websites

For analyzing ThreeJS performance on websites like Unseen Studio, there are several tools available that provide insights similar to r3f-perf:

Browser Extensions

1. Three.js Inspector: A Chrome extension that allows you to inspect Three.js scenes in any website.

   • Provides scene graph visualization
   • Shows performance metrics
   • Allows manipulation of objects and properties

2. Spector.js: A debugging tool for WebGL that captures all WebGL calls.

   • Works with any WebGL application including Three.js
   • Can be used as a browser extension
   • Provides detailed analysis of rendering calls

Built-in Browser Tools

1. Chrome DevTools Performance Panel:

   • Captures frame rates and CPU usage
   • Identifies JavaScript execution bottlenecks
   • Shows rendering performance issues

2. Chrome DevTools Rendering Tab:

   • Enable FPS meter to monitor frame rate
   • Use paint flashing to see which areas are being redrawn

ThreeJS-Specific Methods

You can also examine if a site is using Three.js by checking for specific objects in the console:

JAVASCRIPTCopied
// Type this in the browser console to check if Three.js is being used
window.THREE

If the site uses Three.js, you can then use the WebGLRenderer's extensions to check for supported features:

JAVASCRIPTCopied
// Check for WebGL extensions support
const renderer = THREE.WebGLRenderer.domElement;
renderer.extensions.get('WEBGL_depth_texture');
renderer.extensions.has('EXT_texture_filter_anisotropic');

Monitoring Network Requests

For sites like Unseen Studio, you can also monitor network requests to see:

• What 3D models are being loaded
• Texture sizes and formats
• Asset loading patterns

To do this, open Chrome DevTools, go to the Network tab, and refresh the page to see all resources being loaded.

These tools should help you understand how high-performance Three.js websites like Unseen Studio are built and optimized.
