TD Essentials: Create a Swept Phyllotaxis Operator in Houdini

Plant growth has a strong connection to mathematics. 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.

  1. You seems to be a lot in computational Botanics….

    Do you know grogra.de already ??
    It look like it is a sophisticated grammar for plant stuff.
    Could be too much leaning towards “Botano-Genetik” (oder so), but the Gallery has some nice looking plants, that are apparently possible with this grammar system.

    HTH!
