Snail mail van is 18 shape lines that grow into 27 shapes, with 7 genes the seed draws, 5 motions on 3 joints.
an original delivery van that is half snail: a low rounded body (the foot), a cab with a smile, headlights and a windscreen, eyes on wobbly stalks, a spiral shell for the mail hold with a letter slot and a little flag, and chunky wheels
Each part rides the one before it, so whoever sits at the end feels every motion at once.
The asset line names the model snail_van, titled Snail mail van. complexity=4 holds it to 70 shapes, 6,000 triangles and 4 draw calls; going past any of them is an error.
A gene, L: a value drawn between 2.8 and 3.2 for every seed. This seed picked 2.987. Every line that reads L follows it.
A gene, W: a value drawn between 1.4 and 1.6 for every seed. This seed picked 1.509. Every line that reads W follows it.
A gene, WR: a value drawn between 0.3 and 0.36 for every seed. This seed picked 0.327. Every line that reads WR follows it.
A gene, body: a weighted pick from teal (2 in 8), cherry (2 in 8), cobalt, sunflower, mint or coral. This seed picked cherry.
A gene, trim: a weighted pick from cream (3 in 4) or white. This seed picked cream.
A gene, shellC: a weighted pick from terracotta (2 in 6), peach, honey, oak or lilac. This seed picked peach.
A gene, swirl: a weighted pick from walnut (2 in 4), plum or redwood. This seed picked walnut.
A box, a rounded box standing on the origin (true fillets, crisp colour cuts). It stands at the model's origin. It is a joint, and line 41 hops ±0.015 m: everything on it moves too.
the foot and the cab
A box, a rounded box standing on the origin (true fillets, crisp colour cuts). It rides foot, at (0, .42, L*.24) in its frame.
A box, a rounded box standing on the origin (true fillets, crisp colour cuts). It rides cab, at (0, .46, L*.25-.02) in its frame.
A box, a rounded box standing on the origin (true fillets, crisp colour cuts). It rides cab, at (W*.47-.02, .46, .06) in its frame. 2 copies and a mirrored twin across the parent’s centre line.
A face, a house face (unlit, never inked) on the parent surface: eyes, mouth, blush, brows. It rides cab, at its origin.
A ball, an ellipsoid centred on the origin. It rides cab, at (W*.3, .26, L*.25) in its frame. 2 copies and a mirrored twin across the parent’s centre line. Its ink is glow: unlit, so it reads as a light.
A box, a rounded box standing on the origin (true fillets, crisp colour cuts). It rides foot, at (0, 0, L*.5) in its frame.
A box, a rounded box standing on the origin (true fillets, crisp colour cuts). It rides foot, at (0, 0, -L*.5) in its frame.
A rod, a straight bar from the origin to to, flat ends: poles, legs, rails, spokes. It rides cab, at (.2, .8, .2) in its frame. 2 copies and a mirrored twin across the parent’s centre line. It is a joint, and line 39 rocks ±7°, line 40 tips ±5° and line 44 keyframes on rx: everything on it moves too.
eyes on stalks
A ball, an ellipsoid centred on the origin. It sits at the end of stalk. There is a set on each of the 2 stalk copies, 2 in all.
A ball, an ellipsoid centred on the origin. It sticks to the surface of eye at (0, 4) (azimuth, elevation), lying flat on it. There is a set on each of the 2 eye copies, 2 in all. It draws no outline.
A cyl, a cylinder (or tapered drum) with rounded edges, base at the origin. It rides foot, at (-W*.4, 1.0, -L*.18) in its frame.
the shell: a fat rounded disc with a raised spiral on each side, a letter slot and a flag
A tube, a round tube along points (in the part frame): handles, strings, tails, pipes. It rides foot, at (W*.4+.012, 1.0, -L*.18) in its frame. 2 copies and a mirrored twin across the parent’s centre line.
A box, a rounded box standing on the origin (true fillets, crisp colour cuts). It sticks to the surface of shell at (215, 0) (azimuth, elevation), lying flat on it.
A slab, a flat outline (x,y points) with thickness in z and rounded rims: signs, sails, wings, fins, leaves. It rides slot, at (0, .21, .03) in its frame.
A rod, a straight bar from the origin to to, flat ends: poles, legs, rails, spokes. It rides foot, at (W*.44, .45, -L*.18-.5) in its frame. It is a joint, and line 43 keyframes on rx: everything on it moves too.
A box, a rounded box standing on the origin (true fillets, crisp colour cuts). It rides flagpole, at (0, .64, -.17) in its frame.
A wheel, a chunky wheel on an X axle, centred: tyre, hub and cap. It rides foot, at (W*.47, WR*.55, 0) in its frame. 4 copies in a centred row, (0, 0, L*.62) apart and a mirrored twin across the parent’s centre line.
wheels
stalk (all 2 copies) rocks left and right by ±7°, once every 1.7 s (.6 Hz). The mirrored twin runs 0.5 of a cycle apart, so the pair alternate. Everything on stalk goes with it.
stalk (all 2 copies) tips forward and back by ±5°, once every 2.5 s (.4 Hz). It starts 0.2 of a cycle in. Everything on stalk goes with it.
Hops foot by ±0.015 m, touching down 1.1 times a second. Everything on foot goes with it.
Plays flagpole through keyframes on rx: [0:0 .6:88 .8:80 1:84], one cycle 1.2 times a second. It plays only while the model is in the deliver state, once, then holds its last pose. Everything on flagpole goes with it.
deliver: a state a game triggers; the flag swings down, the eyes glance back
Plays stalk (all 2 copies) through keyframes on rx: [0:0 .3:-22 .7:-22 1:0], one cycle once every 1.3 s. It plays only while the model is in the deliver state, once, then holds its last pose. Everything on stalk goes with it.
