SLIMSHADER is an Open Source Raspberry PI project based on glslViewer and capable of displaying plain images and OpenGL/GLSL shader files.

Let's dig a little bit deeper - http://www.erikoostveen.co.uk/Slimshader.html

Summary

SLIMSHADER is an Open Source Raspberry PI(a) project based on glslViewer(b) and capable of displaying plain images and OpenGL/GLSL shader files.

Shaders are small programs that leverage the power of the GPU to display modern graphics simulations. Visit www.glslsandbox.com to view shaders created by hundreds of artists(c).

SLIMSHADER can display these shaders(d) and modulate them by means of;
▪ Audio
▪ MIDI
▪ Manually tweaking dials
▪ Built-in LFOs (Low frequency Oscillators)
▪ Control Voltage (0 to 5V or 0 to 1V)

SLIMSHADER is a Eurorack format design with HDMI and Analog video output for people who like to add visuals to their music, for video-synth enthusiasts or anyone looking to learn and play with shaders files.

(a) Tested with the Raspberry PI Zero W, Zero 2 W and 3b (v1.2).
(b) Patricio Gonzalez Vivo & Jen Lowe, authors of The book of shaders.
(c) Please note that the SLIMSHADER Raspberry PI image file comes with hundreds of shader files. Credits go out to all the makers of these shaders; their names can often be found in the header of the shader file itself.
(d) Complicated shaders typically require much more CPU/GPU power and a Raspberry PI is not always able to deliver unfortunately - please keep that in mind.

The Slimshader Raspberry PI image

Download the latest Slimshader Raspberr PI image file from Google Drive. You'll need a 16GB Micro SD card (or better 32GB as some 16GB SD cards are actually less than 15GB and the image won't fit).

Specs

3U/28HP = approx. H129mm x W142mm
Depth approx. 45mm
+12V = 250mA, -12V = 80mA, +5V = 0mA
MIDI Type A and/or B (Hardware Jumpers configured)
Supports audio modules Control Voltage (0-5V) and "LZX standard" (0-1V)
HDMI and Analog Video (PAL or NTSC) output
