Look at my new sketch on #openprocessing, ColourCurtain.

The items' colours are altered resulting from the counter value mod 3; thus, only one of the three colour channels is changed, causing the effect of an irregular colour gradient.

Ein kleines Planetensystem mit Proceso
Als eines meiner nächsten Projekte mit PyScript und Proceso möchte ich in drei Stationen eine kleine Animation eines Planetensystems entwickeln. Dabei möchte ich zeigen, wie nützlich für solch eine Simulation die Transformationsoperatoren translate() und rotate() sein können. https://kantel.github.io/posts/2025071301_planetensystem_proceso/ #Proceso #Python #PyScript #Processing #Simulation #CreativeCoding
80 vertices in 2-fold dihedral symmetry has triangle strips of 4 different lengths.
We can also get 80-vertex tetrahedral symmetry with a more "traditional" arrangement of 12 pentagons and the rest hexagons.
Here is an 80-vertex sphere in tetrahedral symmetry with 24 valence-7 vertices.
Tetrahedral symmetry requires that a general point be in a set of 12 -- on each of the 4 faces in each of 3 orientations. You can also add 4 points at the vertices, 4 at each face center, or 6 at each edge center. Combined, any even number of points >= 4 can be arranged with tetrahedral symmetry, albeit not always evenly.
Here is 50 points in tetrahedral symmetry which requires that some of them have valence 7.

50 vertices arranged in D6 symmetry is interesting in that it forms two different but close in length triangle strips -- one following the longitudes and the other the latitudes.

And 22 vertices can also arrange with 2-fold cylindrical symmetry that runs all the pentagons together into one long strip. It produces one long triangle strip and three short ones.

22 vertices can also arrange with 2-fold dihedral symmetry with two strips of six pentagons each separated by a single loop of 10 hexagons. The triangulation has two long triangle strips and two short ones.

40 vertices in tetrahedral symmetry gives a mix of the two with 4 strips that wrap twice and three that only wrap once.

22 vertices can also have tetrahedral symmetry, but now only have four strips that each wrap the sphere twice.

16 vertices gives a triangulation with tetrahedral symmetry. It has 7 triangle strips.

In contrast, the 12-vertex icosahedron has 6 triangle strips.

If you walk triangle strips on this 67 vertex sphere triangulation with 5-fold dihedral symmetry, it makes one complete circuit.
