A good starting point for people who already know how to code and are just looking to understand the core concepts of ISF. The ISF Quick Start is a guide to quickly get started with writing GLSL shaders in the ISF specification.Whether you are a GLSL expert or just getting started, there are several resources and specialized tools that can be useful when writing or remixing ISF compositions. ISF files can be created, viewed and shared online at the website.An example implementation can be found in the ISF Generator Example on Glitch. ISF shaders can be made as full page standalone webpages, with or without controls.The ISF specification was original created for VDMX and is now supported by several different applications as a format including: Generators, filters and transitions in these directories should generally be automatically available within supported software where applicable.

ISF files that you would like to be globally available to all software on your Mac can be placed in the '/Library/Graphics/ISF' or '~/Library/Graphics/ISF' directories.

In many cases, ISF generator files can be directly loaded into the media bin / media player section of host software.

To use ISF files in a specific piece of software consult the appropriate documentation. Shaders written in the ISF specification can be used in supported environments on desktop, mobile and the web. ISF isn't some crazy new groundbreaking technology- it's just a simple and useful combination of two things that have been around for a while to make a minimal- but highly effective- filter format. ISF is nothing more than a GLSL fragment shader with a JSON blob at the beginning that describes how to interact with the shader (how many inputs/uniform variables it has, what their names are, what kind of inputs/variables they are, that sort of thing). The goal of this file format is to provide a simple and minimal interface for image filters and generative video sources that allows them to be interacted with and reused in a generic and modular fashion. ISF stands for 'Interactive Shader Format', and is a file format that describes a GLSL fragment shader, as well as how to execute and interact with it.
