📊 Babylon Lite vs Babylon.js — At a Glance

Averages computed from live benchmarks across all test scenes. Data from bundle/manifest.json and perf-manifest.json.

📋 Per-Scene Breakdown

Scene Bundle (Lite) Bundle (BJS) Ratio RAF ms (Lite) RAF ms (BJS) Speedup Memory (Lite) Memory (BJS) Savings
💡 Live scenes served from Vite dev server. Start with: pnpm dev
💡 Standalone showcase demos built on Babylon Lite — pure Lite, no Babylon.js comparison. Each is production-bundled so its real shipped size is advertised. Regenerate sizes with pnpm build:bundle-demos.

                💡 The same Babylon.js source (lite/src/bjs/sceneN.ts) rendered live through the @babylonjs/lite-compat layer — no code
                changes, just Vite-remapped @babylonjs/core imports. Opt scenes in with "compatParity": true in scene-config.json. A red
                border means the scene hit an unsupported API (LiteCompatError) — that's a concrete TODO for the compat layer.
