In this article we will use previously calculated points as sunflower seeds for building a Voronoi diagram.

This article includes a series of interactive programs, for experimenting with concepts described in previos articles.

If we look at a sunflower, we can see how the arrangement of seeds produces an apparent pattern of interlaced spirals like the one of the image:



In this image, there are 21 red spirals and 34 blue spirals. Both are terms of the Fibonacci sequence.

In this article we will study radial coordinate and its influence on packing and size of seeds.

In this article, we will render a simple sunflower drawing seeds at positions calculated using a simple algorithm.

In this article, we will create a simple example for drawing using a polar coordinate system.

In this article, we will download and install Processing, and we will create a simple sketch (that's how Processing calls its code listings) for drawing a simple figure on screen.

This is the first article of a series about Sunflowers (and other plants), the Golden ratio, the Fibonacci sequence, geometry, maths and computer graphics.

I have ported my Infimines app to Windows and Raspberry Pi.

You can download it here.

I have prepared a small C++ demo for the Raspberry Pi which integrates mouse events in a OpenGL|ES demo environment. It just draws a cross-type mouse cursor and logs mouse events to stdout.

Download the source code for the demo.
