Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: Make 3D art in your browser using Lisp and math
There's also ImplicitCAD (https://github.com/Haskell-Things/ImplicitCAD) which produces STLs, as it is designed for CAD. It uses implicit functions, which I believe are similar to SDFs (I believe the idea is not to necessarily correspond to the distance function).

I printed a waistband tightener to hold my skirt up!
ImplicitCAD is essentially OpenSCAD with bevels.

OpenScad is great, but slow to render.
You might take a look at ImplicitCAD. It accepts OpenSCAD code (as well as some other more exotic formats) and can render much much faster depending on resolution. There's an online editor/renderer here that would tell you whether it can handle your existing code unmodified.

MK4 Printable Parts are now available
If you're looking for examples of high quality openscad code, dotSCAD is pretty cool. nophead (old school reprap person and one of the openscad developers) has a parts library that I think is high quality.

RIP Lin Xinliang (Liang Gege) 1975~2022
Justin Lin passed away due to illness in 2022 at the age of 48.[0]
On December 22, 2022 OpenSCAD posted:
> Today's advent calendar door is a sad one. We'd like to commemorate Justin Lin, who passed away a while ago. In the OpenSCAD community he is best known for his #dotSCAD library. His designs always brought joy and amazement. Thank you, we will miss you.[1,2]
On October 11, 2022 dotSCAD v3.3 released — it was the last commit by JustinSDK on GitHub.[3]

Does anyone know how I could join all the spheres together to create a single curve? I am trying to use the hull() function.

"tria(_p1, _p2, _p3)" module implements "spherical triangle" on sphere, allows for sperical polygon as well
// require https://github.com/JustinSDK/dotSCAD use use use n = 5; radius = 10; thickness = 1; geom = geom_icosahedron(radius); points = geom[0]; faces = geom[1]; for(f = faces) { triangle = [for(i = f) points[i]]; // subdivide the triangle triangles = tri_subdivide(triangle, n); points1 = [ for(t = triangles, p = t) let(unit_vector = p / norm(p)) unit_vector * radius ]; points2 = [ for(t = triangles, p = t) let(unit_vector = p / norm(p)) unit_vector * (radius - thickness) ]; ff = [for(i = [0:3:len(points1) - 3]) [i, i + 1, i + 2]]; color(rands(0, 1, 3)) sf_solidifyT(points1, points2, ff); }

Treble clef dragon
If you are into OpenSCAD, grab this chap's work - https://github.com/JustinSDK/dotSCAD/tree/master/src and use his modules, they are rather good.

Preferred way for rounding corners?
// use // a shape function from https://github.com/JustinSDK/dotSCAD // sq_outer = shape_square(size = 50, corner_r = 5); sq_outer = [[20, -25], [21.9471, -24.6053], [23.5868, -23.4835], [24.6602, -21.8118], [25, -20], [25, 20], [24.6053, 21.9471], [23.4835, 23.5868], [21.8118, 24.6602], [20, 25], [-20, 25], [-21.8118, 24.6602], [-23.4835, 23.5868], [-24.6053, 21.9471], [-25, 20], [-25, -20], [-24.6602, -21.8118], [-23.5868, -23.4835], [-21.9471, -24.6053], [-20, -25]]; // sq_inner = shape_square(size = 30, corner_r = 3); sq_inner = [[12, -15], [13.8551, -14.3577], [14.9158, -12.7057], [15, -12], [15, 12], [14.3577, 13.8551], [12.7057, 14.9158], [12, 15], [-12, 15], [-12.7057, 14.9158], [-14.3577, 13.8551], [-15, 12], [-15, -12], [-14.9158, -12.7057], [-13.8551, -14.3577], [-12, -15]]; polygon( points = concat(sq_outer, sq_inner), paths = [ [each [0:len(sq_outer) - 1]], [each [len(sq_outer):len(sq_outer)+ len(sq_inner) - 1]] ] );
