Time to Next Footstep—
Specifies the number of
frames in each foot movement c ycle. A cycle starts
with the f rame that a foot touches the ground,
continuesasthefootliftsandmoves,andends
with the fra me before the foot touches the ground
again. This parameter is only enabled if Auto
Timing is on.
Speed—Displays the number of units the biped
w ill move per frame. It changes in response to
changes in the other parameters but cannot be
adjusted directly.
The follow ing two parameters are only enabled
when Auto Timing is off.
You c an use these parameters instead of Auto
Timing to control the speed of the forward motion
over the series of footsteps. However, bec ause
these parameters b oth affect the footsteps’ time in
contact with the ground, using them to slow down
a walk gives the walk a hesitant, ‘stop-go’ quality.
Walk Footstep—Specifies the number of frames
each footstep will be on the ground during a walk.
The higher the number, the longer each biped
foot remains in contact with the ground and,
consequently, the slower the speed of the walking
motion.
Footsteps 3 through 5 are on the ground for 22 frames each
Double Suppor t—Specifies the number of frames
both feet wil l be on the ground at the same time
during a walk.
The higher the number, the longer the perio d
duringwhichbothfeetremainincontactwiththe
ground during each walk cycle and, consequently,
the slower the speed of the walking motion.
The dotted l ine surrounds the double-support period (6
frames)

Start Left—Starts t he footstep sequence with a left
step.
Start Right—Star ts the footstep sequence w ith a
right step.
Alternate—Turn on to alternate between right and
left footsteps. When this box is cleared, all of the
footsteps will be either rig ht or left, producing the

Number of Footsteps—Determines the number of
new footsteps to be created.
Parametric Stride Width—Sets the stride width as a
percentage of the pelvis width.
A value of 1.0 produces a stride width equal
