SourceAttributes

Remarks

Parallel arrays alongside the mesh, and that is the documented choice. docs/plan/41-automatic-retopology.md § D12 asks for colours and skinning weights to survive a remesh and leaves open where they live. EditMesh has a normal layer and a texture-coordinate layer and nothing else, and growing it a colour channel and a bone channel would put a renderer's and a rig's vocabulary into doc 24's geometry types — which have consumers that have never heard of either. So they travel beside the mesh, indexed by the mesh's own indices.

⚠ Colours are per corner and weights are per position, and the split is not arbitrary. A colour is a statement about the surface's appearance and can legitimately jump across a seam; a weight is a statement about where the surface moves to, and two corners at one position that moved differently would tear the mesh open.

⚠ Every channel is optional and an empty one means "the source had none", not "zero". A source with no colours must not come back with a mesh painted black.

Fields and properties (4)

• public IReadOnlyList<Vector4> Colors

  A colour or mask per source corner, or empty for none.

• public SkinBinding? Weights

  Skinning weights per source position, or null for none.

• public IReadOnlyList<int>? BoneMirror

  Where each bone's mirror sits, entry i being bone i's, or null for none.

• public static SourceAttributes None

  Nothing at all — a source that is only geometry, which is the generated-blob case.
