ballworld op• Data kinds: none → any (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.icosphere(radius: 'float' = 1.0, subdiv: 'int' = 3) (to call the implementation directly, import ballworld; ballworld.icosphere(radius: 'float' = 1.0, subdiv: 'int' = 3); from the registry, opsdrive.get("icosphere"))
Mesh (V, F) (outward) obtained by subdividing a regular icosahedron (20 faces) 4-way subdiv times and projecting it onto the sphere.
• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).
• Operator provenance and references — the sources of the research/methods this op family came from.
• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
