## What it is
An Android library that renders convex material design shadows for views of any shape, using bitmap outline extraction and the Graham scan convex hull algorithm. It supports shadow offsets, intensity, semi-transparent views, async calculation, and fade animations.

## Use cases
- add material shadows to arbitrary-shaped views in android
- render shadows for semi-transparent views
- compute convex shadows asynchronously without blocking the ui thread
- animate shadow fade out on android views
- use material shadows in a react native app

## When to choose
- you need shadows that follow the actual convex outline of a view's content
- you want configurable shadow offset, intensity, and animations on android

## When to avoid
- you only need standard rectangular or circular elevation shadows built into android
- your view content is highly concave, since only convex hulls are supported
- you need a library under active development

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, graphics, animation
- domain: mobile-development, android-tools, web-design
- platform: jvm
- tags: material-design, convex-hull, graham-scan, shadows, ui-library, android, mobile
