A short playlist showing a couple of examples of merging geometry from an input set of cubes and then CCS subdividing it...

Building the SDS (SubDivisionSurface) from optionally hollow cylindrical sections is working out really well
Could you imagine playing a "not-really-tower-defence" on the inner/outer surface of this?
Need-to-add: pretty much everything, sharp edges, branching...
Please-excuse: lighting, grid positioned by hand in only approximately the right place...

OK, finally got away from cubes... of course, you can't see exactly what shape this is, because I didn't add any normal calculations yet, but "roughly spherical" broadly sums it up...
If I get time tomorrow I'll add the normals, and then look into adding the calculation refinement that lets us tag verts/edges as "sharp"... Combos of sharp and smooth edges let us create all sorts of shapes, like if you leave the top and bottom edges sharp, but the side ones smooth you get a roughly cylindrical shape... Or you can do a block with a hole in it if you do the same thing to the edges around a square hole...

The prompt for Genuary 2025 Day 14 is “ #BlackWhite ” , Day 12 is “ #subdivision ” and Day 17 is “ #Pi=4”
SpheresInBW uses #Hydravideosynth @hydra for subdividing the sketch, #LiveCodeLab for the Black and white component while the coded #SonicPi composition uses pi=4 to arrange the sounds
The motions repeat

Whoa up, Auckland. What's with building subdivisions before putting in sewage systems?
There's Cardinal West (300 homes) where locals are already complaining about the stink. Next month Warkworth Ridge (646 homes) comes on stream, to be followed by Kahawai Point (800 homes) and a 50ha Clarks Beach subdivision in May 2026.
All of these involve trucking sewage from new housing developments. Surely better planning is required?

Some of you think this is probably vaporware by now, but there actually has been a 2D/3D mesh package since 2016, which for various reasons has been dormant for the past few years, since I never got around refactoring & publishing it properly, mostly because some of the features are very low level and in need of a more TS/JS-friendly API (though I made several attempts on that front since).
The mesh implementation combines my favorite modeling, topology & traversal features of Blender's BMesh and SideFX Houdini's attribute system, i.e. attribs which can be attached to different mesh entities: points, vertices, edges, faces and meshes themselves. These can then be used to create groups, colors, metadata & control behavior of operations. There're also three subdivision operators implemented (all attribute aware), one is shown in the example anim... Around ~5 years ago it's even been used in actual (mass) production, i.e. for creating the outsoles & traction patterns of several trainers/shoes by a global footwear/sports brand.
After the upcoming release of the new thi.ng/geom v8.0.0, I'm really hoping to find bandwidth over the summer to finally get back into this... If anyone would be interested in sponsoring/funding part of this work, even better & please get in touch! 🙏 As mentioned, since many parts of the implementation are already quite low level, I'm also going to explore porting it all to Zig and then provide a nice TS/JS API via https://thi.ng/wasm-api... With both projects more stable & proven, this seems pretty feasible (and interesting) to me...

Animated versions... (only tweening uniform displacement value)
Added a new[1] configurable curve subdivision kernel for https://thi.ng/geom to (iteratively) subdivide polygons/polylines with displacement, allowing for super compact code, infinite variation, and beautiful results like shown...
[1] Actually been using this approach since 2010, initially for 3D mesh subdivisions (3rd image)

#HowToThing #021 — Iterative animated convex polygon subdivision and heat map visualization (using poly area as metric)
The main aspect of this example is to show various https://thi.ng/geom shape types, operations & conversions to solve the problem of iteratively dividing convex polygons, whilst considering some aesthetic and geometric constraints. E.g. using the polygon/polyline sampler from https://thi.ng/geom-resample to query the poly boundary, finding & splitting the longest edge, using ray casting to find the opposite split point on the boundary, adding & constraining random variance...
The second part deals with applying this subdivision iteratively, assigning shape colors based on area, animating the whole process and drawing everything to a canvas...
There's a lot to take in here, but all is commented & hope it's not too much for one example! (Please do let me know!)
Demo:

Source code:

The attached animations illustrate the varying split positions (and resulting aspect ratios) and increasing random variance/jitter...
