Carousel is 25 shape lines that grow into 191 shapes, with 7 genes the seed draws, 2 motions on 2 joints and 7 spots where a scene can put people.
an original fairground carousel: a turning deck on a plinth, a striped centre drum, a ring of prancing horses on brass poles that rise and fall in turn, a scalloped striped canopy with a fringe of drops and bulbs, a spire and a pennant
Each part rides the one before it, so whoever sits at the end feels every motion at once.
The asset line names the model carousel, titled Carousel. complexity=7 holds it to 200 shapes, 15,000 triangles and 5 draw calls; going past any of them is an error.
A gene, R: a value drawn between 2.1 and 2.5 for every seed. This seed picked 2.325. Every line that reads R follows it.
A gene, PH: a value drawn between 2.1 and 2.4 for every seed. This seed picked 2.371. Every line that reads PH follows it.
A gene, NH: a whole number drawn from 5..7.4. This seed picked 7.
A gene, stA: a weighted pick from cherry (3 in 7), cobalt, teal, grape or bottle. This seed picked cherry.
A gene, stB: a weighted pick from white (3 in 5), cream or sunflower. This seed picked cream.
A gene, deckC: a weighted pick from cream (2 in 4), white or peach. This seed picked cream.
A gene, metal: a weighted pick from brass (3 in 4) or silver. This seed picked silver.
A cyl, a cylinder (or tapered drum) with rounded edges, base at the origin. It stands at the model's origin.
the plinth and the turning deck
A cyl, a cylinder (or tapered drum) with rounded edges, base at the origin. It rides plinth, at (0, .16, 0) in its frame. It is a joint, and line 47 spins about Y: everything on it moves too.
A cyl, a cylinder (or tapered drum) with rounded edges, base at the origin. It rides deck, at (0, .12, 0) in its frame.
A cyl, a cylinder (or tapered drum) with rounded edges, base at the origin. It rides drum, at (0, PH*.82, 0) in its frame.
A cyl, a cylinder (or tapered drum) with rounded edges, base at the origin. It rides drum, at (0, PH, 0) in its frame.
the canopy: a striped band with drops and bulbs, a scalloped roof, a spire with a pennant
A ball, an ellipsoid centred on the origin. It rides band, at (R+.16, 0, 0) in its frame. 28 copies spread evenly round band's Y axis.
A ball, an ellipsoid centred on the origin. It rides band, at (R+.19, .17, 0) in its frame. 14 copies spread evenly round band's Y axis. Its ink is glow: unlit, so it reads as a light.
A cone, a cone (or frustum with r2), base at the origin. It rides band, at (0, .34, 0) in its frame.
A cyl, a cylinder (or tapered drum) with rounded edges, base at the origin. It rides roof, at (0, 1.05, 0) in its frame.
A ball, an ellipsoid centred on the origin. It sits at the end of spire.
A slab, a flat outline (x,y points) with thickness in z and rounded rims: signs, sails, wings, fins, leaves. It rides spire, at (.04, .14, 0) in its frame.
A rod, a straight bar from the origin to to, flat ends: poles, legs, rails, spokes. It rides deck, at (R*.72, .12, 0) in its frame. 7 copies spread evenly round deck's Y axis.
the horses, one per pole
A ball, an ellipsoid centred on the origin. It rides deck, at (R*.72, 1.05, 0) in its frame. 7 copies spread evenly round deck's Y axis. It is a joint, and line 48 bobs ±0.12 m: everything on it moves too.
A limb, a capsule hanging DOWN from the origin (a joint at the top): arms, legs, necks (rot to aim). It rides horse, at (0, .48, .4) in its frame. There is a set on each of the 7 horse copies, 7 in all.
A ball, an ellipsoid centred on the origin. It rides horse, at (0, .52, .52) in its frame. There is a set on each of the 7 horse copies, 7 in all.
A face, a house face (unlit, never inked) on the parent surface: eyes, mouth, blush, brows. It rides head, at its origin. There is a set on each of the 7 head copies, 7 in all.
A cone, a cone (or frustum with r2), base at the origin. It rides head, at (0, .08, -.08) in its frame. 2 copies and a mirrored twin across the parent’s centre line. There is a set on each of the 7 head copies, 14 in all.
A tube, a round tube along points (in the part frame): handles, strings, tails, pipes. It rides horse, at its origin. There is a set on each of the 7 horse copies, 7 in all.
A tube, a round tube along points (in the part frame): handles, strings, tails, pipes. It rides horse, at (0, .08, -.36) in its frame. There is a set on each of the 7 horse copies, 7 in all.
A ball, an ellipsoid centred on the origin. It rides horse, at (0, .12, -.03) in its frame. There is a set on each of the 7 horse copies, 7 in all.
A rod, a straight bar from the origin to to, flat ends: poles, legs, rails, spokes. It rides horse, at (.08, -.06, .24) in its frame. 2 copies and a mirrored twin across the parent’s centre line. There is a set on each of the 7 horse copies, 14 in all.
A rod, a straight bar from the origin to to, flat ends: poles, legs, rails, spokes. It sits at the end of fleg. There is a set on each of the 14 fleg copies, 14 in all.
A rod, a straight bar from the origin to to, flat ends: poles, legs, rails, spokes. It rides horse, at (.08, -.1, -.24) in its frame. 2 copies and a mirrored twin across the parent’s centre line. There is a set on each of the 7 horse copies, 14 in all.
A ball, an ellipsoid centred on the origin. It sits at the end of fshin. There is a set on each of the 14 fshin copies, 14 in all.
A ball, an ellipsoid centred on the origin. It sits at the end of bleg. There is a set on each of the 14 bleg copies, 14 in all.
No geometry: a saddle: a person sits astride, facing +Z, on horse, one per copy: 7 in all. A scene's ride <who> on <thing> or do <who> sit at <thing> line fills it. It moves with everything above it: deck (turns once every 20 s) and horse (bobs ±0.12 m once every 2.5 s). Each motion rides the one before, so a rider feels them all at once.
a rider astride every saddle, facing the head: they rise and fall with the horse
Spins deck round its Y axis once every 20 s (.05 Hz), forever. Everything on deck goes with it.
horse (all 7 copies) rises and falls by ±0.12 m, once every 2.5 s (.4 Hz). Each copy runs 0.37 of a cycle behind the one before, so they move in turn. Everything on horse goes with it.
