I want to make a specimen with variable mesh size from 100 mm to 25 mm. [image]

I don’t know if you refer to a 2D or a 3D situation… anyway I think the key point for having variable voronoi size is to create the points that define the voronoi diagram itself with same distance distribution so, from your image, the sizes you have indicated should be -for each zone- the distances…

Anyone have any example grasshopper script to make variable Voronoi mesh size? If you have please share or share your own ideas. Thanks

Hello One way to do that is to use points at 2 specific distances. Pack big spheres on top and bottom. Little spheres on middle then use points to make a 3d voronoi

Here is the script I thought about First generate points in a volume, a lot of point is better so Populate Box is not the best as it will try to place points not too near. I used my component from Nautilus plugin [image] Then for each point set a radius. I use a simple formula to but a radius fo…

Instead of Mirror I modified the code, but either way, there are many ways to get the large/small/large pattern. Setting “mesh size from 100 mm to 25 mm” is difficult to do precisely. [gradient_points_voronoi_2024_Jul5b] gradient_points_voronoi_2024_Jul5b.gh (27.4 KB) Increasing the PopGeo ‘N’ …

Thanks for sharing your script. The plugin Grasshopper for the object “Volume” needed version >7.35. My one is v7.0. Is it possible to avoid the Volume object by any means. Thanks.

Volume is not useful here, I just used it to measure things and control the results. If you don’t have a new version of Rhino, just copy the components not blank on a new definition. voronoi variable.gh (12.4 KB)

Hello

I think you miss some points. This is not a do-my-work-for-me group, point 7 here

For sure sometime we do this on this forum because the subject is interesting or fun.

So if you want some help, show us what you have done, the kind of geometry you have …
