Shaders Under Control

Описание: Testing out a program for controlling GLSL shaders with either the computer keyboard or MIDI. It can load up to 12 different shaders into a program, and you can control up to 8 parameters for the animation in addition to colors, zoom, pan, rotation, and speed.
Here it’s controlled by a MIDI track in Bitwig. It has an export mode, so when satisfied, you can export the control track to a MIDI file and use that to render a high‑quality video file.
The song is based on the riff from    • Bitwig 5.3, Dome Filter and Phase Modulation  
I’m using shaders from Shadertoy. They need some small tweaks to make them work, and if you want additional control, you can add parameters that will be exposed as uniforms in the shader.

Used shaders:
Pulsing circle weave: https://www.shadertoy.com/view/7d23zG
A Spiral of Circles: https://www.shadertoy.com/view/Md2yWR
Stellar magnetic field: https://www.shadertoy.com/view/3lc3WN
Crosses: https://www.shadertoy.com/view/MscSW8
Shifting arrows animation: https://www.shadertoy.com/view/MsdBDM
Radiolarian #3: https://www.shadertoy.com/view/4sdGzs
Bit for bit: https://www.shadertoy.com/view/MsV3Wt

Some of them I have parameterized, so they don’t look exactly like on Shadertoy.
