can you please post some details as to the errors involved? i assume you’re talking about grasshopper v something something 0043?

sorry, one more question: I’m just starting out in Rhino and GH and have more experience in 3ds max so I was thinking about exporting the file so that I can make further alterations in that program. Have you done this or do you work exclusively in Rhino? Whats the best way to go about it? Any suggestions would be really appreciated. Thanks again for sharing all of this, very exciting stuff.

hey dimitrie thanks for great work you have done. I am attempting to delete the reference points from the example file and input new ones that I specify but I’m having some trouble getting it to display the new 3d voronoi based on those points. I was just wondering how I might alter the script so that I can use my own points. Thanks so much.

how do you get the ‘referenced assemblies’ window to come up? sorry, somewhat new to code…so i can’t follow where the window is coming from.

hey marcel, try this out:

the error is fucked up, hopefully the topic above helsp.
also thanks for the heads up

Hi man, thx for this work, would be consider for the gh developers for next releases. I’m researching the voronoi parameter in architecture, and, your definition appear the best interest way. But I’ve a problem, Can u help us for the people that so show the message: “script exception: Acces Denied”.
I’ve thinking it should be, for that i have updated my system until Framework 3.5 (not only Framework 2), or I wrong and the qhull would work right anyway.
Please discuss about

hey javi, just select from grasshopper the final nodes of your sketch (the geometry should turn green in the viewport) and then click the bake button (an egg) from the toolbar. that should work.

Hi Dimitrie.. I’ve been working with your 2d voronoi definition lately and making some extrudes with attractor points, and its been working great for the aproach I’m looking for.. but I’ve only been working for several weeks and I don’t know if I can render something out of grasshopper directly, or how can I render any model, or maybe I’m going the wrong way, do you know any tutorial I can look for? or what do you recomend me to do? Thanks!

update: I think I figured it out. I outputted the curves to a planar node then took the two outputs (from polygon and curves) and trimmed one from the other and baked that. It seems to be giving me what I want.

Thanks again for your help and let me know if you would have done it differently.

Thanks for your quick reply Dimitrie! I am trying to bake the component labeled “curves” that’s attached to the D output of qhull and nothing is showing up when I click on it and then bake.

I find that if i feed the “curves” node into the Planar component (instead of the poly), I can then bake the generated surfaces themselves, but that doesn’t really give me the curves. should the “curves” component be fed into something else?

hey dan, this sounds like a gh problem, not from my side. Are you sure you are not baking the scripting component, but the little parameter boxes in which i feed the curves output of the node?

By: Dan

Dan — Sat, 17 Oct 2009 03:57:28 +0000

Hi Dimitrie, this is a great definition. I just have a somewhat beginner question. It seems like I can’t really bake the generated curves. when I highlight the curves and click bake, nothing happens. Do you have any advice for this? Thanks!

Hi, thanks for this little tutorial, I’m all new to this parametric world and this is verry helpfull !!
Verry nice blog actually, I’ve been around it and I really like the urban bacteria, really interesting work!!

Thank you dimitrie.
But, still I curious about generating void voronoi diagram like http://dimitrie.wordpress.com/2009/04/30/qhullghlove/.

Could you upload your script?

dimitrie stefanescu — Tue, 11 Aug 2009 11:20:05 +0000

well, pointset reconstruction was doing some very expensieve boolean operations to get stuff inside the box (basically cutting out everything that was outside) – you can’t do that yet effectively inside gh.

bake and cut is the only solution i can give you for now.

And how can I generate a hall on generated model?
