Except the start point coordinates of the leaf origin x0 & y0
(arbitrarily set to 10 and 40) all coordinates are relative to this origin.
Most of the parameters are random generated, except for some of them (e.g.,
to close polygons, or to keep the stalk and the mid vein on the same
line).
Usage
gen_leaf_parameters(
x0 = 10,
y0 = 40,
dx10 = sample(8:12, 1),
dy10 = 0,
dx21 = sample(12:20, 1),
dy21 = sample(-4:-10, 1),
dx32 = sample(10:18, 1),
dy32 = stats::runif(1, 0.92 * (-dy21 - 1), 0.95 * (-dy21 - 1)),
dx43 = sample(4:6, 1),
dy43 = y0 + dy10 + dy21 + dy32,
sx0 = stats::runif(1, 0, 0.1),
sx1 = sample(1:3, 1),
sx2 = sample(4:6, 1),
sx3 = sample(2:4, 1),
sx4 = stats::runif(1, 0, 0.2),
sy0 = stats::runif(1, 0.5, 1),
sy1 = sample(-4:-6, 1),
sy2 = stats::runif(1, -0.5, 0.5),
sy3 = stats::runif(1, 0.5, 1.5),
sy4 = stats::runif(1, 0.2, 0.7),
smx1 = sample(-5:-15, 1),
smx2 = sample(-5:-15, 1),
smy1 = stats::runif(1, -1, 1),
smy2 = stats::runif(1, -1, 1)
