Hi, I really need your help. How can I generate pore spheres in voronio structure? As shown in the picture below. [example3.PNG] [example4] To open the attachment , you need Plug-In: Dendro . I used Rhino 6. [pore spheres generate-voronoi porous structure1] [pore spheres generate-voronoi poro…

Haven’t used dendro, but you can try this method: pore spheres generate-voronoi porous structure.gh (14.0 KB) [image] [image]

It dose not work. The spheres need to make contact with the structs that surrounds it, but not planes. Here is DENDRO DendroGH.gha (57 KB)

If you do that, the spheres might start colliding with each other at some places pore spheres generate-voronoi porous structure.gh (13.8 KB) [image]

The spheres do not contact to the structs, and some spheres cross the structs. [image]

Here’s the updated file: pore spheres generate-voronoi porous structure.gh (13.2 KB) [image] [image] The spheres are doing exactly as is mentioned in your post: [image]

Read what you have posted, it is exactly as described: Sphere having centre as the centroid of the polyhedral voronoi cell and radius equal to shortest distance to the cylindrical surface of beam If you need them to touch all the struts, it is nearly impossible (only possible in certain voronoi …

In the image from the paper looks voronoi cells from equal spheres. Voronoi cells in grasshopper have different volumes, you need something like TriRemesh in 3d space [image] Introducing TriRemesh - high quality triangular and hexagonal remeshing and shrink wrapping Grasshopper …

Have a look also at this example [image] Refine a mesh Grasshopper No, it is under the Surface>SubD tab, (and only if you have your update frequency set to Release Candidate and have downloaded the latest version of Rhino 7) about optimizing the distribution, one way woul…

The sphere should as large as possible until it makes contact with the structs. Maybe the center of the sphere is not the center of the cell. As picture shows below, the sphere is small.
