Against a photograph this was the worst model in the kit: an amorphous
pale lump with spikes in it, where the reference is plainly a drum of
straw with three cords round it.
Three numbers were doing the damage. The body is a seven-sided lathe --
too few sides to read as round on its own -- and it was then displaced by
0.045 of the height, which is 19 mm against a radius of 210 mm. A tenth of
the radius is not texture, it is deformation, and it left no axis to
recognise. Meanwhile the ends were pulled in by a third, turning the
silhouette into a cinched sack rather than a bale with the broad flat ends
the cord holds it square against. Thirteen sides, a sixth of the
displacement and a third of the end fade, and the form comes back. The
stray stalks are what should say "loose straw", and they can only do that
against a body that holds its shape -- so they are shorter too, since at
0.30 of the height they read as spikes driven in rather than stalks
working loose.
The cords were worse, in the quiet way. The ring radius was written as
`0.5 * cinch(x) + cord * 0.35`, which adds four millimetres to a
normalised 0.5: the body is built in radius-1 space and squashed
afterwards, so anything radial has to be in those units. The hoop stood
0.0044 proud before the squash and 1.85 mm after it. Three cords have been
modelled, merged, exported and invisible in every render this model has
ever produced. They are now expressed in the body's own units and sit in
the groove they pull, which is what a tie does.
