Processing Flowers for the livingroom

I created another set of images to hang on my livingroom wall. Here is an example of the generated images and the code of the sketch I used

processing flowers

The code creates a petal with no stroke and an pastel fill color and then redraws the shape 3 times without a fill color.

processing blob

Nikolaus Gradwohl2013-09-26T04:04:47+00:00

this sketch creates an animated blob by drawing 10 bouncing ellipses with random sizes two times at slightly different sizes to create an effect that looks similar to metaballs or lava-lamps, but can be computed very fast and easy.

Click on the picture to see it running or download the code

neon lines in processing using a glsl filter

I made a short processing script that draws sine curves and uses a glsl blur filter to add a neon effect


To create this effect you need a processing sketch drawing the curves and a glsl filter that adds the blur effect.

endless pattern generator

Nikolaus Gradwohl2013-08-12T06:20:38+00:00

Back in my Atari computing days I was fascinated by the endless pattern generators that generated never repeating complex patterns on my screen. This is a processing sketch that recreates this effect

click on the sketch to generate a new pattern

I created a new small processing sketch, cause I had to wait for someone and there was nothing else todo - well at least nothing else that I would have liked to do or that would have fit into that timeslot. Somehow this blogpost starts to get far more complicated than I intended it to be ...

I think you should just click on the image and rotate the rectangles ...

processing archflower

Nikolaus Gradwohl2013-05-31T06:17:17+00:00

My latest processing sketch uses the arc command to create flowers. I use 20 arcs and control their angle with the x axis of the mouse. The arcs grow at different speeds and on random sides of the flower to create the petals.

Click on the sketch to create a new flower and move the mouse to let it bloom.
