distance

Tree Settings
map size:
resolution of the shadow map.
x

z
shadow:
strength
strength of the shadow.
decay
ratio the shadow decreases as the distance from a node increases.
distance
the maximum distance a node's shadow will reach vertically downward. Higher values are more realistic but take longer to compute.
seed
reset tree
Simulation Settings
shoot direction:
weight of different factors when computing shoot direction.
tropism η
weight of gravity in shoot direction.
0: no effect
< 0: downward tendency
> 0: upward tendency
light η
weight of light in shoot direction. Higher values cause the tree to seek out light more.
tree η
weight of the tree's genetics in shoot direction. Higher values make the tree look more organized and self similar.
light
ambient light exposure at each point.
energy α
energy multiplier at base of tree. Higher values give tree more energy.
energy λ
how energy is split at branches.
.5: balanced
< .5: bias towards lateral branch
> .5: bias towards main branch
prune ratio
ratio
(ENERGY/NUM_CHILDREN)
at which branches are pruned. Higher values cause trees to drop branches more often.
branch θ
direction a lateral branch will grow:
0: perpendicular to main axis
> 0: towards main axis
