Hello community,
I’m fairly new to Grasshopper and I’m trying to recreate radiolaria-like shapes. I’ve learned how to use Voronoi on surfaces and on spheres, and while it works on simple surfaces, it doesn’t seem to work when I use SolidUnion or more complex geometry.
Right now I’m at the stage where I need to project NURBS curves, but SolidUnion doesn’t work with Split Surface, so I’m stuck.
Are there easier or more reliable ways to extrude these Breps?
A second question: I’m looking for something similar to an attractor point, but applied to spheres, so I can vary the hole sizes in the radiolaria structure.
Make four copies of each sphere, each larger than the last. Use the middle two to make the shell. Intersect the inner and outer ones with the Voronoi and make the outlines on each. RuleSrf between them, and subtract from the shell.
A bit of a different look to what’s shown in your image, but this was one of the examples I made for Exoskeleton (a precursor to Multipipe) 13 years ago now (how time flies!).
Thank you a lot for your dedicated work! I checked this one before. Is a different Radiolaria from the specific Radiolaria in the screenshot from the screenshot but the script is totally useful to see how it comes together. Thank you for sharing!
Actually also very interesting how to change the size of the holes like in the picture of radiolaria. I’ll try to inversigate it in the next steps. And also add spikes on it. Can send here the progress if I’ll have it
