classPolygonShape

@codexo/exojs-physics / physics / stable

A convex polygon defined by ≥3 local-space vertices. Input vertices may be given in either winding; they are canonicalised to counter-clockwise and the outward edge normals are precomputed. Construction throws on any non-convex, degenerate, or under-specified input — there is no silent repair. Vertices and normals are exposed as flat `[x0, y0, x1, y1, …]` arrays to keep the narrow phase allocation-free; both are frozen.
