3D Web – Babylon.js for Your Web App

Modern business applications are anything but boring. Data needs to be visualized understandably and appealingly. Web graphics engines like BabylonJS help us do just that. They enable 2D, 3D, virtual, and augmented reality content to be presented comprehensibly. Thus, among other things, digital concepts can be visualized, configured, and tested – cross-platform and performant. In this session, Max Schulte shows how you can integrate BabylonJS and Angular in an exemplary way, so that both technologies can unfold their full potential in tandem. Learn by live coding how to integrate a graphics engine yourself and achieve your goals.

19. 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
20. 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
21. 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
22. 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
