## Description

GPUImage2 is a Swift framework for applying real-time filters and effects to images and video using the GPU. It provides a real-time video filter library, an image geometry manipulation engine, and an OpenGL shading pipeline for processing visual data on graphics hardware.

The framework enables the construction of visual effect pipelines by chaining image sources to consumers in sequential flows. It supports the development of custom fragment and vertex shaders for bespoke image processing and offers the ability to bundle these operations into reusable units via graph-based grouping.

Capability areas include color adjustment, geometric manipulation, and the generation of synthetic images. The system also supports composite image layering, allowing multiple image sources to be combined using alpha blending and chroma keying.
