3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar Can I Use - WebGL v1 10.05.2020 • CAN I USE SCREENSHOT + DATE BabylonJS https://caniuse.com/#feat=webgl 

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar Clarifying keywords • GameObject (TransformNode) à Logical objects • Can hold visual objects and much more • The root of all possible things • Mesh à Visual objects • Scene (Stage) à holds information • Engine à renders the Scene BabylonJS Babylonjs.com 

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar How changes happen • Iterations (loop, render loop) • Fixed steps relative to each frame • Setup everything then modify something • Step by step, no reordering etc. BabylonJS

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar BabylonJS - Angular Angular • UI • Application lifecycle • Dependency injection • NgZone (ZoneJS) • Service, Context Integration BabylonJS • 3D • Engine lifecycle • Scene graph • Event-based system • Render loop 

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar Render Loop • Fast iterating • One image (or frame) each iteration • Static execution order (lifecycle dependent) • 60 frames per second (FPS) desired BabylonJS 

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar 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) BabylonJS 

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar Two Different Lifecycles Angular • DOM • Event Integration BabylonJS • 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-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar Change Detection 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( … ); à * (window as any).__Zone_disable_requestAnimationFrame = true; 

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar Clear responsibilities • Factory • Lifecycle hooks • Naming • Extend existing BabylonJS classes • Scene • Mesh • Don’t mix (a mesh must not be a component) My integration key points 

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar Dependency Injection • Provide access to context • Don’t mangle with providing all necessary dependencies (chains) • Re-Use Angular (or other’s) tools • Key to integrate Angular and BabylonJS Factory

Add engine object Get new engine object instance Creator = services, components, game objects … Angular Architecture Overview (Factory) 

3D-Visualisierung in Web Apps: Angular und BabylonJS in Symbiose Webinar Composition over Inheritance • Add “behavior” to a Base • Flat hierarchy • Reusable and extendable • Code example: BoxSlot, StackSlot and Ground Design Concept for Engine Objects
