This tool is a development interface for chaining glsl fragment shaders.

Trello board

✔️ Load a chain of shaders from json and add passes at runtime.

✔️ Define their uniforms and map them to midi keys.

✔️ Render out to pngs with a duration and fps (good for making loops!)

✔️ Custom texture sizes

✔️ Feedback buffer for each pass available as json param

✔️ Fly around 3d wasd/mouse camera controls that map to uniforms (for exploring raymarched worlds).

✔️ Texture input

✔️ Audio input

Disclaimer: Very early stages. Great tools I've used like this in the past include Hedron and Veda.

#Compiling From Source

Make sure you have all the addons listed above. Checkout this repo into your OpenFrameworks "apps" folder. Move ofShader.cpp and ofShader.h into your_open_frameworks_dir/src/gl (it has some extra stuff to store errors) Run "make" then "make run"
