I’ll have to study those for sure

Isopod - implicit surface tools

I’m still putting together a full collection of examples, but here are a few very basic ones for starters: (Install Isopod from the Rhino PackageManager command before trying these definitions) primitives_and_booleans.gh (29.9 KB) offset.gh (83.2 KB) shelling.gh (92.2 KB) TPMS.gh (20.4 KB) field_display.gh (31.1 KB) cut_mesh_with_field.gh (18.2 KB) kangaroo_pull_to_isosurf.gh (20.3 KB) root_find_wrap.gh (14.3 KB)

I’m only like 12 posts in, and my mind blown already.

Look at the new isopod plugin

Here’s an infill example:

so cool!

@DanielPiker

(these examples are all fairly flat just to make it easier to see, but this all works for volumes too, not just in 2d)

aligned_spinodoid_example2.gh (54.5 KB)

So there you have it, a way to generate stochastic curved surface structures with local alignment and scaling. These have potential applications in structurally optimised infill for lightweight parts, medical implants, heat exchangers…

This is all fairly new and experimental. Spinodoids are a relatively recent invention, and I’ve only recently made this implementation. The use of the bump function weights to combine point sampled inputs as a way of controlling the anisotropy is my own twist here.
A big part of the aim with Isopod was to make this sort of experimentation possible. I’d be interested to see how anyone applies or develops these ideas further.

@martynjhogg

It looks like it could have an application in 3d print infill.
