UnverifiedContinuous animation properties (such as opacity and transform) have calculable intermediate values, allowing browsers to generate smooth transition frames through interpolation algorithms.70% similarUnverifiedGodot引擎的AnimatedSprite2D节点原生支持序列帧动画，开发者设置播放帧率通常为8-24 FPS即可实现流畅角色动画67% similarUnverifiedBrowsers use GPU-accelerated rendering for CSS animations, delivering excellent performance.66% similarUnverifiedInteractive content relies on a real-time computation loop (Game Loop/Render Loop) that ideally reads user input, updates state, and renders output 60 times per second—a characteristic that pre-encoded video does not possess.65% similarUnverifiedThe transition of offset-distance belongs to composited layer animation; the browser can handle displacement during the GPU compositing stage without triggering main-thread reflow or repaint, enjoying the same level of performance advantage as transform animations.62% similar
