From cebdec9dbb06db744d6318658ffa51267ef738ef Mon Sep 17 00:00:00 2001 From: Devesh Bervar Date: Sat, 28 Mar 2026 14:44:21 +0530 Subject: [PATCH] feat: animate pileup interactions sequenced by timestamp (#235) - Add PileupInteraction and PileupEvent types to event-data.ts - Add animatePileup() to AnimationsManager with timestamp-based sequencing - Each interaction fires a vertex flash at its specific (x,y,z) position - Add _animateInteractionTracks() for real per-interaction track animation - Expose animatePileup() through ThreeManager and EventDisplay public API - Add Animate pileup button to animate-event UI component All 179 existing tests passing. Tested on ATLAS sample: 10 sequential vertex flashes visible along beam axis, each separated by ~1 second. --- .../src/event-display.ts | 20 ++ .../src/lib/types/event-data.ts | 34 +++ .../three-manager/animations-manager.ts | 195 +++++++++++++++++- .../src/managers/three-manager/index.ts | 17 ++ .../animate-event.component.html | 8 + .../animate-event/animate-event.component.ts | 61 +++++- 6 files changed, 321 insertions(+), 14 deletions(-) diff --git a/packages/phoenix-event-display/src/event-display.ts b/packages/phoenix-event-display/src/event-display.ts index 6283026b0..3eb380987 100644 --- a/packages/phoenix-event-display/src/event-display.ts +++ b/packages/phoenix-event-display/src/event-display.ts @@ -15,6 +15,7 @@ import { URLOptionsManager } from './managers/url-options-manager'; import type { PhoenixEventData, PhoenixEventsData, + PileupEvent, } from './lib/types/event-data'; declare global { @@ -803,6 +804,25 @@ export class EventDisplay { this.graphicsLibrary.animateClippingWithCollision(tweenDuration, onEnd); } + /** + * Animate multiple pp interactions from a single bunch crossing (pileup), + * sequenced in time order using the timestamp stored on each interaction. + * + * Each interaction produces a brief vertex flash and then its tracks are + * drawn out proportionally to its timestamp relative to the bunch crossing. + * + * @param pileupEvent Object containing all pileup interactions with timestamps. + * @param totalDuration Total duration of the full pileup animation in ms.
