Especially the special phyllotactic distribution pattern shows up a lot in nature. Be it the head of a sunflower, a pinecone or a pineapple. The dense packing of seeds and other organs on the surface of these is due to the golden angle phi. In this tutorial Manuel shows you how to implement a phyllotaxis operator with VEX in Houdini. But instead of just implementing the flat disc model we try something a little more sophisticated and build a phyllotactic pattern on a surface of revolution. Download the Setup Read the Paper
