## What it is
An open collection of GLSL transition shaders that smoothly animate between two textures using a progress value from 0.0 to 1.0. It follows the GL Transition Specification v1 and is distributed as an npm package with a companion gallery website.

## Use cases
- add crossfade and wipe effects between video frames
- animate transitions between two images in a WebGL app
- find reusable GLSL transition shaders for a video editor
- implement slideshow transitions in the browser
- apply stylized transitions in a motion graphics pipeline

## When to avoid
- you need CPU-based image transitions without shader support
- you need a full video editing framework rather than transition shaders
- you require a permissive license for redistribution and cannot accept the custom license terms

## Facets
- artifact type: dataset
- maturity: stable
- function: graphics, animation
- domain: graphics, web-development, media
- platform: cross-platform
- tags: glsl, transitions, webgl, video-editing, shaders, open-collection, shader, gpu
