VERY EARLY DEVELOPMENT

fragFrame 0.01

A quick way to experiment with frag shaders

fragFrame is a quick way to create interesting patterns with frag shaders. It is currently in very early stages of development.

Requirements

• GNU/Linux
• make
• gcc
• libglfw3
• libglfw3-dev
• libglew2.0
• libglew-dev
• entr

How to use

Install dependencies

sudo apt-get install libglfw3 libglfw3-dev libglew2.0 libglew-dev entr

Make fragframe

make

Run fragframe

./fragframe_run.sh

Edit shader.frag and your frame will automatically update once you save

Uniforms

A number of useful uniform variables are provided in fragframe, these are as follows:

• u_time (float) - The amount of time in seconds the shader has been running for
• u_mouse (vec2) - The x and y position of the cursor
• u_resolution (vec2) - The resolution of the frame window

Notes

• If you are using vim and want syntax highlighting, add the following to your vimrc:

au BufReadPost *.frag set syntax=c

• Currently only GLSL version 130 is supported

• A green screen indicates a bad shader
