Just a bunny rotating according to a uniform set of directions on the sphere. The bunny is colored towards the "overhang" angle with respect to the ground. The black area on the ground is the projection of the bunny onto the ground (a bit like a shadow). This is a simple toy simulation that computes some metrics relevant to the simulation of 3D printing preparation.

Nice to see Michael Hansmeyer still following his dreams: The White Tower was finally revealed 2 weeks ago, currently the largest 3D printed structure in the world (30 meters [90ft] tall), located in a small village in Switzerland:

(It was an honor teaching a workshop about my open source geometry, voxel, subdivision & physics tools to his MAAS students at ETH Zurich some 15 years ago, when he/they first started fabricating generative 3D sculptures/structures...)

Working on nested triply periodic lattices. Here a Gyroid levelset image is created and two interwoven/complementary surfaces are obtained by constructing isosurfaces for the same positive (white) or negative level (red). In the animation the levelset level is adjusted so the surfaces "shrink away" from each other.

More on Gyroids: en.wikipedia.org/wiki/Gyroid)

Was working on surface closure methods, and was using a torus as a test surface (since it has two "periodic" mesh directions to close over).

Son: "What yah making papa?"
Me: Oh I'm using this doughnut to..
Son: That is not a doughnut! That is the wrong color.
Me: Okay, let me render it brownish and..
Son: No, you need to add chocolate too, and sprinkles of all colors!
Me (15 min later): Got it!

Meet the n-trapezohedron.

Recipe: put 2*n points around the equator, and 2 more for the poles. Now form n top faces and n bottom faces (all quadrilateral). Now alter the points so that all faces are planar.

High n-values give spiky diamond like things. But the special case with n=3 produces the humble cube!

‼️ Announcing the thi.ng user survey 2024 📋

forms.gle/XacbSDEmQMPZg8197

**To achieve a better sample size, I'd highly appreciate if you could circulate the link to this survey in your own networks.**

It's already been almost 9 years since the last user survey for these projects. Please help me/us to get more insights into your own experiences, your interests, hopes and pain points — allowing the projects and everyone involved to move forward more intentionally.

There're 15 questions here, with ~10 of them marked as mandatory. The main focal points are the matrices in the middle of the survey. Please also do use the final freeform comments box to share any further feedback you might have. Thank you very much for your interest, trust & taking the time to provide some much needed answers! 🙏

The survey is anonymous and will remain open until 23:59 (CET) on February 29, 2024. I will then share a public summary of the results on my Mastodon in the days following (do keep an eye on the #ThingUmbrella hashtag)...

Nothing new, but maybe a little unusual: Using boids as alternative to Lloyd relaxation and/or Poisson-disk sampling. The boids here are using only two behaviors: local separation, plus a randomized attractor to create global disturbances. Cell density could also be varied by spatially adjusting the separation distance between boids. Overall convergence/relaxation can be much faster than shown here...
