## Description

iCarousel is a data-driven UI library for macOS and iOS used to build interactive three-dimensional scrolling experiences. It functions as a customizable view controller that renders paged content using cylindrical or cover-flow 3D effects.

The component is distinguished by its programmable perspective and visual transformation hooks, which allow for the definition of custom 3D styles and bespoke animation effects. Users can adjust viewpoint distance, alpha fading, and foreshortening to control how the vanishing point and depth appear during navigation.

The library manages high-performance view recycling by loading necessary item views on demand from a data source. It covers broad capability areas including interactive content navigation, coordinate-based item detection for touch events, and the management of dynamic item insertion and deletion.
