## What it is
An Android library providing OpenGL-based canvas views (GLView, GLTextureView, GLContinuousView) that let you draw bitmaps, animations, and image filters on SurfaceView or TextureView like a traditional Canvas. It offers GPUImage-style filter APIs and integrates with camera preview.

## Use cases
- draw custom views with opengl on android
- apply gpuimage-style filters to bitmaps
- render high-performance animations with opengl
- draw camera preview with filters on textureview
- replace glsurfaceview with textureview for opengl drawing
- custom android view with gpu-accelerated drawing

## When to choose
- you need Canvas-like drawing backed by OpenGL on Android
- you want TextureView benefits like alpha and z-ordering with OpenGL rendering
- you need GPUImage filters plus custom drawing in one view

## When to avoid
- you only need standard 2D drawing without GPU acceleration
- your project targets Android below API 14
- you need OpenGL ES 3.0+ features

## Facets
- artifact type: library
