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.

processing lissajou generator

I wrote a processing lissajou form generator. I didnĀ“t use the usual connect the dots method but used two nested loops to connect every point to every other point. The line color, width and alpha is calculated from the distance of two points.

Nikolaus Gradwohl2013-03-16T09:56:14+00:00

Writing talking processing sketches just got a lot easier!

So starting with processing 2 beta 7 you can install the ttslib by clicking on "Sketch -> Import Library ... -> Add Library". In the dialog that opens enter ttslib as a search filter and then click on the install button next to the ttslib entry.

I generated a new set of pictures for my living-room today. This time I created an abstract art generator that creates random curves and draws circles that follow them, I also made it choose a base color at random and create the colors in the HSB colorspace depending on the size of the curve
