ecotect analysis grid 2 rhino This tutorial runs you through the process of exporting your rhino geometry into ecotect and then bring the analysis grid data back into rhino. The method shown is a work around – numeric data is imported into rhino as a heightfield surface, then Grasshopper is used to read the height, which is then used to control the dimension of other geometries. For this tutorial, you’ll need this Rhinoscript, Grasshopper definition, and Sample Data 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.

The arising concentric ring patterns are reminiscent of bacteria and fungus growth, no surprise then that the BZ reaction can be used as a model for biological development. As with all kinds of patterns of periodicity, the hallmark concentric gradients of BZ reaction seem to crop up in other domains too and at much different growth rates. Flickr provides a great hunting ground for some fine Banded Agates from across the globe. Banded Agate The Laker Agate has a distinctly bacteriopoetic arrangement of organisms growing upon tangerine facade. Hans Jenny, in his book Cymatics, notes that the effect of sound waves on liquids and powders also has the ability to shape the substances into banded hydrodynamic and precipitative landscapes, once more mimicking the chemical oscillations of the BZ reaction.
