simplify is undoable, NOT queryable, and NOT editable.
This command operates on a keyset. A keyset is
defined as a group of keys within a specified time range on one or
more animation curves.
The animation curves comprising a keyset depend on the value
of the "-animation" flag:
-
keysOrObjects:
- Any active keys, when no target objects or -attribute
flags appear on the command line, or
- All animation curves connected to all keyframable
attributes of objects specified as the command line's
targetList, when there are no active keys.
-
keys:
Only act on active keys or tangents.
If there are no active keys or tangents, don't do anything.
-
objects:
Only act on specified objects. If there are no objects specified, don't
do anything.
Note that the "-animation" flag can be used to override
the curves uniquely identified by the multi-use
"-attribute" flag, which takes an argument of the form
attributeName, such as "translateX".
Keys on animation curves are identified by either
their time values or their indices. Times and indices can
be given individually or as part of a list or range (see Examples).
This command will simplify (reduce the number of keyframes) an animation
curve.

Argument types |
Properties |
|
animation(an)
|
string
|
|
|
Where this command should get the animation to act
on. Valid values are "objects," "keys," and
"keysOrObjects" Default: "keysOrObjects." (See
Description for details.)
|
|
attribute(at)
|
string
|
|
|
List of attributes to select
In query mode, this flag needs a value.
|
|
controlPoints(cp)
|
boolean
|
|
|
This flag explicitly specifies whether or not to include the
control points of a shape (see "-s" flag) in the list of attributes.
Default: false. (Not valid for "pasteKey" cmd.)
In query mode, this flag needs a value.
|
|
float(f)
|
floatrange
|
|
|
value uniquely representing a non-time-based
key (or key range) on a time-based animCurve. Valid
floatRange include single values (-f 10) or a
string with a lower and upper bound, separated by a
colon (-f "10:20")
In query mode, this flag needs a value.
|
|
floatTolerance(ft)
|
float
|
|
|
Specify the x-axis tolerance (defaults to 0.05) for
float-input animCurves such as those created by "Set Driven Keyframe".
This flag is ignored on animCurves driven by time. Higher floatTolerance
values will result in sparser keys which may less accurately represent
the initial curve.
|
|
hierarchy(hi)
|
string
|
|
|
Hierarchy expansion options. Valid values are "above,"
"below," "both," and "none." (Not valid for "pasteKey" cmd.)
In query mode, this flag needs a value.
|
|
includeUpperBound(iub)
|
boolean
|
|
|
When the -t/time or -f/float flags represent a range
of keys, this flag determines whether the keys at the
upper bound of the range are included in the keyset.
Default value: true. This flag is only valid when
the argument to the -t/time flag is a time range with
a lower and upper bound. (When used with the "pasteKey"
command, this flag refers only to the time range of the
target curve that is replaced, when using options such
as "replace," "fitReplace," or "scaleReplace." This
flag has no effect on the curve pasted from the clipboard.)
|
|
index(index)
|
uint
|
|
|
index of a key on an animCurve
In query mode, this flag needs a value.
|
|
shape(s)
|
boolean
|
|
|
Consider attributes of shapes below transforms as well,
except "controlPoints". Default: true. (Not valid for "pasteKey" cmd.)
In query mode, this flag needs a value.
|
|
time(t)
|
timerange
|
|
|
time uniquely representing a key (or key
range) on a time-based animCurve. See the code
examples below on how to format for a single
frame or frame ranges.
In query mode, this flag needs a value.
|
|
timeTolerance(tt)
|
time
|
|
|
Specify the x-axis tolerance (defaults to 0.05 seconds)
for time-input animCurves. This flag is ignored on animCurves
driven by floats. Higher time tolerance values will result in
sparser keys which may less accurately represent
the initial curve.
|
|
valueTolerance(vt)
|
float
|
|
|
Specify the value tolerance (defaults to 0.01)
|
|
Flag can appear in Create mode of command
|
Flag can appear in Edit mode of command
|
Flag can appear in Query mode of command
|
Flag can have multiple arguments, passed either as a tuple or a list.

# Keys on animation curves are identified by either
# their time values or their indices. Times and indices can
# be given as a range or list of ranges.
# time=('10pal','10pal') means the key at frame 10 (PAL format).
# time=[('1.0sec','1.0sec'),('15ntsc','15ntsc'),(20,20)] means the keys at time 1.0 second, frame 15 (in NTSC format), and time 20 (in the currently defined global time unit).
# time=(10,20) means all keys in the range from 10 to 20, inclusive, in the current time unit.
# Omitting one end of a range means "go to infinity", as in the following examples:
# time=(10,None) means all keys from time 10 (in the current time unit) onwards.
# time=(10,) means the same as (10,10)
# time=(0,10) means all keys up to (and including) time 10 (in the current time unit).
# time=(None,None) is a short form to specify all keys.
# index=(0,0) means the first key of each animation curve. (Indices are 0-based.)
# index=[(2,2),(5,5),(7,7)] means the 3rd, 6th, and 8th keys.
# index=(1,5) means the 2nd, 3rd, 4th, 5th, and 6th keys of each animation curve.
