Strength Sets the degree of effect the vectors have on the movement of an
object entering the vector field. If
Show Vector Field on page 4921 is on as you
adjust Strength, you can see the vector lines change size in the viewports in
real time. Default=1.0.
NOTE Sometimes, after changing strength, vectors will be too large or too small.
In such cases, adjust the
VectorScale on page 4921 parameter so that they display
properly.
Falloff Determines the rate at which the strength of the vectors falls off with
distance from the surface of the object. Default=2.0.
A value of 0 will make all the vectors the same size. A value greater than 0 will
make them get smaller as they get farther away from the object surface. A
value less then 0 will make them get larger as they get farther away.
Parallel/Perpendicular Sets whether the force generated by the vectors works
parallel or perpendicular to the vector field. Default=Perpendicular.
Because the vectors are perpendicular to the object surface, and you typically
would want delegates to travel parallel to the surface, you would normally
use a perpendicular force.
Pull Adjusts objects' position relative to the field. Available only when
Perpendicular is chosen. Default=0.0. Range=-1.0 to 1.0.
Objects moving perpendicular to a vector field sometimes tend to drift away
from it, due to lack of subsampling. The Pull parameter helps to pull objects
back. Pull values greater than 0 create a pulling force towards the source of
the vector field vector. Values less than 0 pull the force towards the direction
in which the vector field's vector is pointing. A value of 0.0 produces a force
perfectly perpendicular to the vector field's vector.
