{"params":{"colorway":{"type":"choice","default":"turning-maple","label":"Season","describe":"THE SEASON KNOB, and also the colorway: it re-tones all five zones at once and at winter-bare it deletes geometry, so the triangle count moves with it. turning-maple is the shipped build and the reference tree \u2014 a maple caught mid-turn, green lower tier, gold middle tier, deep red crown, over dark bark. summer-green puts the whole crown in leaf: a dark green skirt, a light green middle and a mid green crown. autumn-gold has the turn reaching the skirt \u2014 olive low, gold middle, amber crown. deep-crimson is late autumn, a gold skirt under an amber middle and a deep red crown. In those four leafed seasons no twig shows: the crown closes at its top lump and the tree is as tall as its foliage. winter-bare strips EVERY foliage mass and leaves the bare tree: trunk, the two lifted limbs, five mid boughs and the forked crown twigs spraying up to about 1 m above the line where a leafed crown closes, so the bare tree stands about 1 m taller than a leafed one. It is the only season that shows twigs.","affects":"geometry","options":["turning-maple","summer-green","autumn-gold","deep-crimson","winter-bare"]},"leafLow":{"type":"color","default":"#5f9a4b","label":"Lower canopy tier","describe":"Albedo of the WIDEST, lowest tier \u2014 three chunky lumps clustered round the trunk at about 3.35 m across, the last part of a maple to turn, so green in the default build. One uniform tone on every facet: the lumps are real faceted geometry and the scene lights shade them. Must sit a clear step away from the middle tier or the two fuse and the layered read (the whole point of this tree) dies."},"leafMid":{"type":"color","default":"#f0c05a","label":"Middle canopy tier","describe":"Albedo of the middle tier \u2014 two lumps with a real gap at the front that the crown tier drops into. Gold in the default build. The turn runs from the crown down, so this zone is always exactly the tier under the top one: at four tiers the extra tier is skirt and takes the lower tone, and at two tiers it is not used."},"leafTop":{"type":"color","default":"#c94f3d","label":"Crown canopy tier","describe":"Albedo of the topmost tier \u2014 one narrower angular lump, the first part of the tree to turn and so the deepest colour in the default build (red). This is the tone the tree is named by at a distance; keep it the boldest of the three."},"bark":{"type":"color","default":"#4a3527","label":"Bark (trunk, limbs, boughs)","describe":"Albedo of the straight six-column trunk, the two lifted limbs and the five mid boughs \u2014 one uniform dark brown, because the taper, the flare and the flat columns are real geometry. Clearly darker than the twigs and far darker than any foliage tone, so the fork reads as a dark Y of daylight under the crown."},"twig":{"type":"color","default":"#8c6a47","label":"Twig wood","describe":"Albedo of the thin forked crown twigs and of every branch fork \u2014 parts that exist only at season winter-bare, so in the four leafed seasons this zone paints nothing and the knob changes nothing visible. A lighter, tanner wood than the trunk bark: these are pencil-thin and seen against the sky, and at bark tone they vanish. Not a highlight \u2014 young maple wood really is paler than the trunk."},"canopyHeight":{"type":"range","default":2.5,"label":"Canopy height","describe":"How high off the ground the canopy is carried, in metres of clear trunk below the foliage: 1.75 m is a squat maple with the skirt near head height, 2.78 m a leggy one that stands clear of the kit oak in a row (total height in leaf, which is the crown top, about 5.7 m to 6.7 m, 6.43 m at the shipped default; at season winter-bare the twig spray takes it to about 6.7 m to 7.8 m; the range is skewed downward because the tree is already tall for the kit). REBUILT, not scaled: the trunk gains RINGS at a constant 0.88 m pitch and the limbs and boughs re-solve against the new crown, so the triangle count moves with the knob. Trunk girth, root flare, tier pitch and every foliage mass are untouched \u2014 a tall one is a leggier tree carrying the same head.","affects":"geometry","min":1.75,"max":2.78},"tiers":{"type":"range","default":3,"label":"Canopy tiers","describe":"How many stacked foliage tiers the crown is built from, at a constant 1.15 m pitch. Tiers are added DOWNWARD \u2014 the crown top and the tree height stay put and the foliage reaches further down the trunk \u2014 so this changes how skirted the tree is without changing how tall it is. 2 is a spare two-band maple with a lot of trunk showing; 3 (shipped) is the reference tree, green-gold-red; 4 is a full tree whose skirt hangs to just above the fork. Each tier is a real cluster of lumps, so the triangle count moves. The turn runs from the crown down: the top tier always takes the crown tone, the one under it the middle tone, and every tier below that the lower tone, so a four-tier maple is a red cap over gold over a deep green skirt.","affects":"geometry","min":2,"max":4,"step":1},"crownTwigs":{"type":"range","default":6,"label":"Crown twigs","describe":"How many forked twigs spray out of the top of the BARE tree at season winter-bare, splaying up and outward to about 1 m above the line where a leafed crown closes; every other one carries a small fork. At 3 the bare crown is sparse, a couple of stray shoots; at 6 (shipped) the reference spray; at 9 a shaggy halo that widens the winter silhouette at the top. In the four leafed seasons no twig is built (a leafed maple closes at its top foliage lump and shows no twig), so this knob changes nothing until the season is winter-bare.","affects":"geometry","min":3,"max":9,"step":1},"scale":{"type":"range","default":1,"label":"Scale","describe":"Scales the whole model; 1 is as built.
