Tree Properties
In this rollout we may adjust the tree properties and other
general parameters.
Width
This value defines the width of the trees. This parameter
is linked with the distribution map, so if the width increments,
it's possible that the distribution map's increments automatically
also. The reason is to maintain a top limit for the the density
of trees (see distribution map's parameters for details).
Height
Height of trees (in scene's units).
Geometry
The trees, by default, are created as rectangular planar objects
witrh a tree texture and an opacity map. If we see them from
a front view, they have the aspect of tree required, but they
look deformed from other viewpoint. This is corrected using the
options of camera rollout (see this section for details) o also
we may create them with two perpendicular planes ('Two Planes'
option). With two planes, the 3D effect is maintained more accured
from all viewpoints (without using the camera rollout) and also
is useful for creating a more compact shadow.
Also, we can use custom meshes for trees. Select it with the
'Pick' button of this rollout. We must be care using only low
face models, because the total number of faces of Forest object
is equal to the number of faces of this model multiplied by total
of trees.
By default, all trees have the same size of the custom mesh
model, but if we enable the 'Ignore mesh dimensions' checkbox,
they will have the size defined in Widht and Height parameters.
Icon Size
When the plugin object cannot create trees (because have not
been defined all the required parameters), it built a icon with
a 'F' sign inside. This parameter defines the size of the icon.
Random Seed
This is a any numeric value used to initialize the random
number generator. This number affects to the random transforms
of material, position, scale, etc. when they are used (see transform
and material rollouts). For a same value, the trees always have
the same transformations. |
