Drag Sp ace Warp 67
Inter face Timing group
Time On/Time Off—The frame numbers at which
the space warp becomes active and becomes
inactive.
Damping Characteristics group
This group lets you choose Linear Damping,
Spherical Damping, or Cylindrical Damping, plus

Unlimited R ange—Whenon,Dragexertsfull
damping strength over an unlimited range. When
off, the Range and Falloff sett ings for the current
damping type take effect.
•
Linear Damping—Motion for each particle is
separated into vectors for the space warp’s
localX,Y,andZaxes. Theareaoverwhich
damping is exerted for each vector is an infinite
planewhosethicknessisdeterminedbythe
corresponding Range sett ing.
X Axis/Y Axis/Z Axis—Specifies the percentage
of particle motion along the local Drag space
warp axis that’s affected by the d amping.
Range—Sets the t hickness of the "range plane,"
ortheinfiniteplaneperpendiculartothe
specified axis. Takes effect only when Unlimited
Range is turned off.
Fa lloff—Specifies the distance beyond the X,
Y, or Z Range within which Linear Damping
is applied. Damping is strongest at the Range
distance, decreases linearly out to the limit of
the Falloff, and has no effect beyond that. While
Falloff takes effect only beyond the Range, it
is measured from the center of the icon, and
always has a minimum value equal to the Range
value. Takes effect only when Unlimited Range
is turned off.
•
Spher ical Da mping—When Drag operates in
Spherical Damping mode, its icon is a sphere
within a sphere. Particle motion is broken up
int o radial and tangential vectors. Damping
