Solid porous voronoi structure and porosity percentage

Hey Guys, I need your help with creating a porous structure in Grasshopper based on Voronoi tessellation. The structure I have developed so far can be seen in the pictures below, including the corresponding Grasshopper file. I have got 2 specific questions: How can you determine the volume of the structure in order to calculate the percentage of porosity? I used the Volume and the Mass Addition components to determine the mass of the (bounding)box. However, I was unable to do this for the ro…

Apply 3D Voronoi to Volume

Hello everyone, I’m relatively new to grasshopper. i try to use a 3d voronoi on a given volume. what I try to achieve you can see on the picture. I would like to apply this to different shapes and influence the cell size with attractors. Whats the best way to achieve this? anyone done something like this before? [yrtb]

Merging 3D Voronoi Network into one unified object

Hello, I am trying to create a network of 3D Voronoi branches to model a collagen fibers within a matrix. As I create the structure in Grasshopper and bake it in Rhino, I export it to either SolidWorks or Ansys Space Claim to finally export it to Ansys workbench for finite element analysis. The problem is that when I export the file (Parasolid), it is not read as a unified objects, but as the assembly of lots parts. I would appreciate if somebody help me to export it the 3D Voronoi network as a…

Voronoi 3D - Loft component does not create all the surfaces

Hi, I’m an architecture student. I need to use voronoi 3d for my final project. I’ve been working according to a tutorial but there’s bug that I have and I cannot solve it. I made the mesh from Rhino, not grasshopper. After Voronoi 3D, I get the curves but when I loft them, some of the surfaces are not created. If I apply with 800 points, half of them are gone, if I chose 750 nearly all of them appears but I cannot achive to have all them. Sharing the screenshot. I’ll be really happy if someone…

Voronoi Mesh Rabbit Grasshopper

Hello. Can anyone help me take a normal closed mesh form and apply a Voronei effect. I can only find Voroni tricks with shapes like spheres and flat boxes but not a closed mesh. Any help would be great. Thank you. Ian [0000002265_bunny-voronoi-pattern-3d-printing-model_800-3893952644]
