convex_hull — 3D `bounds` op

• Data kinds: points → mesh

• Call: import fullseye as fs; fs.ledger.convex_hull(V) (to call the implementation directly, import meshrepair; meshrepair.convex_hull(V); from the registry, ops3d.get("convex_hull"))

Usage

Convex hull of a point set -> (V, F) with outward-oriented triangles.

Thin wrapper over scipy.spatial.ConvexHull (Qhull): interior points are dropped, faces are triangulated, and each triangle is wound so its normal points away from the hull centroid (outward, positive signed volume) — so the result feeds straight into inertia_tensor or a MuJoCo convex collider. Needs at least 4 non-coplanar points.

• blender_interop — Using Blender alongside — build the shape, measure it with fullseye (pitfalls: axes, units, ground truth)

References (sample data, literature)

• 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.
