Summary & Key Takeaways ​

• Codrops presents a tutorial on building a "dual-scene fluid x-ray reveal effect" using Three.js.
• The technique involves blending two distinct 3D scenes with a fluid simulation for a dynamic visual transition.
• This article is aimed at developers looking to implement advanced and creative graphics effects on the web.

Our Commentary ​

Codrops tutorials tend to be well-documented even when the technique is non-trivial. The fluid simulation is mostly decorative here — the more transferable concept is the render target switching and mask compositing approach, which applies to plenty of other transition types. If you work with Three.js, the compositing pattern alone is worth pulling from this.
