Chromium Blink: Scroll-Triggered Animations on the Compositor Thread

This document explores the technical implementation of scroll-triggered animations within Chromium's Blink engine and compositor. Unlike traditional scroll-driven effects that track movement continuously, these animations are initiated by specific scroll offsets or visibility thresholds. To ensure smooth performance, the system promotes eligible animations involving properties like opacity and transform to the compositor thread, bypassing potential main-thread congestion. The text details the internal C++ architecture, explaining how classes like blink::Animation and cc::Animation synchronize to manage the animation lifecycle. Developers are encouraged to use declarative CSS triggers and compositor-friendly properties to avoid expensive layout recalculations. Ultimately, this multi-threaded approach allows for complex, jank-free visual effects that remain responsive even during heavy processing tasks.
