Aeolian dune simulation (made in 2017) for #MeerMittwoch:

The images show a screenshot of the JavaScript application to create the simulation and some Houdini renders of exported height fields. The sim itself had 5 macro params to control the behavior of the interactive deposit/erosion/transportation process. It supported tileable patterns, customizable seed terrain (images) and ran realtime at ~30fps. The profile (cross-section) visualization was important because the tool was intended to create traction patterns for footwear...

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...)

In a world that’s rapidly embracing innovation, architecture and engineering are no longer just about drawing lines or sketching beautiful forms. They’ve become deeply rooted in computation, algorithms, and smart design processes that harness the power of Topology Optimization to create more with less. #AIinArchitecture #ComputationalDesign #DigitalFabrication #TopologyOptimization

A century-old enigma, graph theory and design
Behind a static form, there are connections, transformations and, above all, the elegance of mathematics.

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.

Working on automated quasi-structured hexahedral meshing of branched structures in #Comodo.

My current solution features a lot of fun tricks, e.g. ray tracing, distance marching, surface smoothing, Bezier splines, lofting, thickening etc.

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!

And truncating these (cutting the spikes off) is fun too.

Here I cut so the upward edge lengths are the same as the equatorial edge lengths. It produces rather pleasing pentagonal rings.

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!

Meet "Perlin noise". A useful and pretty way to generate noise. Perlin noise is used often in computer graphics/games/animations to create structures/textures/landscapes.
The algorithm features so-called "gradient vectors" (shown in black). The Perlin image intensities stem from smooth interpolation of local dot products with these gradient vectors.

My implementation is in #JuliaLang, source to follow soon.
