Cheers,

I host a blog for my Generative Algorithms course at Florida International University, SOA. Delighted to come across your site. I will add you to my blog roll for my students to explore and look forward to exchanging definitions and concepts for the further discourse of parametric design, generative algorithms, and fabrication in architecture.
Best Regards,
Jovan Rodriguez Yapur

Hello there…
Thanks for publishing the adaptive facade definition. I just downloaded it and tried to open it with GH, but I got an error message stating ” ‘gh_point2d’ is an unexpected token. Expecting white space. Line 1381, position 75″, which forces me to quit. Any idea how to get around this problem. I am using GH version 8.0062 with Rhino RS9. Thank you.

  Hi Zayad,
  Thank you for your feedback… It is strange actually. I works perfectly on GH 0.8.0062 with sr8..My first thought on this error could be on the VB.net components this definition uses, but the code seems ok. I re-uploaded the def try it out now!!
  
  Regards,
  Marios

Hey Marios thanks for sharing your great work, it’s really helpfull and mind opening. Especially for someone who’s taking his first steps in Grasshopper like me. I was wondering if you finally got to upload the definition for your isoflock project, I can’t seem to find it anywhere and I’d like to give it a try for a school project.
Anyway thanks again and keep up the great work.

  Apostolis,
  
  Thank you for your kind words. If you open the page with chrome the download link should be there. If you need the flocking part, i can’t release it, cause its related to my current research. But you can refer at either SI and locust add-ons for GH.
  Best,

Hi Marios,

First, thank you for posting this incredible work! I’ve been playing around some of the definitions, it seems the only one I can’t get to work is the HoneyComb_Boundary.ghx file – the definition opens fine, but nothing appears in the rhino interface? Does the definition need a specific type of geometry (surface, curve, or closed polysurface) to run? And if so which component does the geometry plug in to? Thanks.

  Hi Derek,
  It should work if you get a surface into the geometry component, one in orange colour probably.

Marios,

Again Great work and Thank you for Sharing! 🙂

I am actually starting to do my own research in that topic, I am still trying to grasp the beginning stages of trying to script swarm behavior. Hopefully in the future you would be able to express the logic and process to achieving a swarm behavior with a couple agents, and the next stages to actually developing a form. I know if have to do some more research, but I have always wondered what the process or the train of thought would be to generate a form/mesh from such a behavior (using the data-curves, points,etc..). Thank you for all you have done and for sharing you work!

  Hello Ramzi,
  
  Thank you for your kind words. to start coding boid I would suggest to start looking into Craig Reynolds original procedural algorithm on this theme. First one and also best one. From this starting point you can move into creating your own rules of interaction in between the boids which will consequently lead to emerging morphologies, again with another set of rules translating the agents to geometry.
  
  Let me know if you can’t find resources, so I can point you to the right direction.
  Most of them are mentioned in this paper:

hi.
thanks for the great work you are sharing with us.
Actually I’m beginner in GH. I downloaded the diagrid definition (Diagrid Panels VB), it worked the first time i tried it ( it was great). but now i am trying to repeat the same steps; I’m getting the error: “index was out of range. must be non negative and less than the size of the collection.
parameter name: index (line: 0 )”. would you please help me solve this problem, I appreciate your efforts so much… thanks in advance

  Hi Sam,
  
  Unfortunately I can’t tell much without a screenshot or a file. From the error you’re getting my bet goes on wrong number of points provided, non 2-dimensional array of points, or wrong number of panels in rows or columns.
  Hope this is helpful for you.

  Ok,
  Your surface should be untrimmed for this script to run. As I roughly guessed before, you are not getting a two dimensional array of points, and some rows/columns have less points, hence the error.
  try a surface from a sweep2 or a rebuilded one.
  Best,
  M.

Hi,

I would love to experiment with your tetra aggregation script however it doesnt seem to be working for me. I am fairly new to using hoopsnake and the component is not included within the script and I am having trouble making it work. Is there any way to perhaps show me how to do it? Would be greatly appreciated. Thank you and congrats on the amazing work!

  Hi Naomi,
  
  Thank you for your kind words.
  Hoopsnake is an add-on. You have to download it from food4rhino and install it yourself.
  Then if you reopen my def it will work like a charm.

Hi,

I came across your site recently and I’ve seen your work more specifically the tentative Grasshopper Generated Tentacle Organisms / Structures, I’ve been attempting to do it but I’m having problems with the flockofboids_3D and another one that has “point array, rows, columns, out, panel frame, cenPoint and surfaces”, after reading your comments I understand that the “flockofboids_3D” is a script you wrote but the second one I can’t figure out which plug-in you used, please can you help me?

Thanks,

Kind regards,

CC
