Made with noise and 2 digital video feedback loops.

#feedback #noise

(The original animation looks much crisper. But will be as mp4 file many 100 KByte large. So here is the highly compressed version.)

A rotating noisy pattern in gray scale. Plus an overly of rectangles inverting the brightness.

"into the dark"

Made another #GLSL filter for the smartphone. It is a bit frustrating to take photos with this manipulation because Safari crashes after every shot on my smartphone. OK, it's too much for the device when you push it to the limit.

Today #GPN22 in neon colors.

OK, the colors are not manipulated. Only the geometry has been messed up by me.

Adhesive tapes that glow in UV light. In heavily distorted geometry. Some of the text fragments are still recognizable. There was also the outline of a shark. But this shark has probably been completely absorbed by the distortion.

@noneuclideandreamer Ein erster und unvollständiger Versuch dein Dynamical Systems Project als Fragment Shader zu implementieren. Sieht aus als würde es mit 30fps laufen, Auch dann noch wenn man die NVIDIA GPU deaktiviert.

Es läuft auf dem "analog Not analog" System. aNa verwendet für die Visualisierung #openFrameworks.

The colors are manipulated with a #GLSL shader directly in the smartphone during the shot.

The geometric distortion is a dipol conformal map. It is made with #GMIC as post processing.

@noneuclideandreamer Da habe ich eine Frage:

Gibt es ein Paper in dem das Konzept beschrieben ist wie die Komplexe Zahl auf den RGB Würfel abgebildet wird. Die Funktion colormap sieht für mich allgemein verwendbar aus. Also immer anwendbar wenn ich einen Vektor der Länge 2 auf einen Farbraum abbilden will.

Pixel sorting with #Hydra

#glitch

Stripes in blue and beige tones dissolve. Glitch effects become visible. The image changes its color to brown-green tones.

I am trying to sample a texture "incorrectly" with #OpenGL. A noise function is supposed to provide the displacement error. It doesn't work properly yet, but it looks quite interesting.

So far i thought it would be complicated to give photos this look.
Here it was simple: the green channel is greatly reduced in intensity. Blue somewhat amplified. That it looks so alien to us is probably because we expect a fresh green in this motif.

A distorted fern leaf.

This picture was created in several steps:

First, slowly moving the camera over the leaf. The result is a short movie, not yet the final still image.

Then split the frames of this movie into approximately 4200 individual images.

Now cut out a narrow circular strip from each image.

At the end, put all the strips together to form the final image.

Don't worry: I'm not doing it by hand. It's a combination of ffmpeg and self-written Java software.

Trying #databending on an image. This is not really the expected result.

Because heat slows down the thinking I have braked out this video.

#openFrameworks

The overlay of two videos. And with reduced colors. Driving cars can be seen in yellow tones. A very jerky movement, because this video is played back only with 20% of the original speed.

Another attempt with a Perlin Noise in a digital feedback loop. In post-processing, the grayscales were mapped onto a palette.

#lisp #openFrameworks

(ns lv.demo)
(use 'lv.core)

(layout "grid" [ras0 mopr1] [ras2 frag3])
(render 3)

;noise source
(hsv :ras0 [mopr1]
(v (unoise (* mopr1.v 6 y) (+ x y)))
)

;morphological operator
(expr :mopr1 [ras0] "eeeebbbbb")

;damping
(hsv :ras2 [ras2 ras0]
(v (mix ras2.v ras0.v ks1))
)

;palette
(expr :frag3 [ras2]
"frag/pal_Browns-And-Yellows.frag"
)

In the feedback loop, organically acting capillaries become visible.

Two drawings of flowering plants are superimposed. The drawings become visible through the movement of colored shapes. A hummingbird also becomes visible.

I am currently trying to extract the dominant colors from photos. Later i want to create color palettes with 4 to 16 different colors. Color Quantization is not accurate. It can create interesting contrasts in false colors.

#imageMagick

Reduced to 4 colors. CMY color space for calculating the 'color distances'.
Reduced to 12 colors. HSB color space for calculating the 'color distances'.
16 colors. XYZ color space for calculating the 'color distances'.

Sometimes it moves.

#glitch

An 8x8 LED field recorded by a WEB camera. The colors are strongly manipulated. The image stands for a few seconds. Then changes position and comes to rest again.
