3D Web – Babylon.js for Your Web App Session LIVE CODING

Lifecycle • Different steps executed by the render loop • Static execution order • Move from “manipulate it now” to “I instruct you to manipulate it at the correct time” mindset • see: Angular’s changeDetectorRef.markForCheck • Syncs the “state” with the “view” (physics not included) Babylon.js 3D Web – Babylon.js for Your Web App Session

Two Different Lifecycles Angular • DOM • Event Integration Babylon.js • Loop à e.g. dispose on next iteration • Different timings can cause synchronization problems à Lifecycles should be separated à No dependency from BabylonJS to the Angular lifecycle / change detection cycle à “Add box to scene” becomes “Add box on next iteration” 3D Web – Babylon.js for Your Web App Session

Change Detec5on Angular • NgZone (ZoneJS) • Checks on every event Integration BabylonJS • Event-based communication • Events on every frame (60 FPS!) • Exclude BabylonJS from the NgZone à ngZone.runOutsideAngular( … ); • Stop zone.js to observe animation frame requests à (window as any).__Zone_disable_requestAnimationFrame = true; 3D Web – Babylon.js for Your Web App Session

Clear responsibilities • Separate contexts • Lifecycle hooks • Naming • Extend exisdng BabylonJS classes • Scene • Mesh • TransformNode • Don’t mix (a mesh must not be a component) My integration key points 3D Web – Babylon.js for Your Web App Session
