Argument types |
Properties |
-cutoffFrequency(-cof)
|
float
|
|
|
Defines the cutoff frequency (in Hz) for the Butterworth filter.
|
|
-endTime(-e)
|
time
|
|
|
Specify the end time of the section to filter. If not specified, the last
key of the animation curve is used to define the end time.
|
|
-filter(-f)
|
string
|
|
|
Specifies the filter type to use. The avalible filters are:
butterworth
euler (default)
gaussian
keyReducer
peakRemover
keySync
resample
simplify
|
|
-keepKeysOnFrame(-kof)
|
|
|
|
When specified, a secondary filter pass is applied to position keys on whole
frames. This flag is only supported by the Butterworth filter.
|
|
-kernel(-ker)
|
string
|
|
|
The resample kernel is a decimation resampling filter used to resample
dense data. It works on the keyframes and may not produce the desired results
when used with sparse data.
The resample filter converts from either uniform or non-uniform
timestep input data samples to the specified uniform timeStep. Various
time domain filters are available and are specified with the kernel
flag which selects the resampling kernel applied to the keyframes
on the animation curves.
Kernel Values
| closest |
Closest sample to output timestamp |
| lirp |
Linear interpolation between closest samples |
| box |
Box filter: moving average |
| triangle |
Triangle filter: (1 - |x|) weighted moving average |
| gaussian2 |
Gaussian2 Filter: (2^(-2x*x)) weighted moving average |
| gaussian4 |
Gaussian4 Filter: (2^(-4x*x)) weighted moving average |
This filter is only targeted at decimation resampling
-- interpolation resampling is basically unsupported. If your
output framerate is much higher than your input frame rate
(approximate, as the input timestep is not assumed to be regular)
the lirp and triangle will interpolate (usually) and the rest will
either average, or use the closest sample (depending on the
phase and frequency of the input). However this mode of operation
may not give the expected result.
|
|
-keySync(-ks)
|
|
|
|
When specified, a secondary filter pass is applied that adds a key to sibling
curves (X,Y,Z) for each key that is encountered. This flag is only supported by the
Key Reducer filter.
|
|
-maxTimeStep(-mxs)
|
float
|
|
|
|
-minTimeStep(-mns)
|
float
|
|
|
|
-period(-per)
|
float
|
|
|
|
-precision(-pre)
|
float
|
|
|
Defines the precision parameter.
For the Key Reducer filter, this parameter specifies the error limit between the
source and output curves. Greater values reduce precision. Lower values increase
precision.
|
|
-precisionMode(-pm)
|
int
|
|
|
Defines whether the precision value should be treated as:
0: An absolute value
1: A percentage.
|
|
-preserveKeyTangent(-pkt)
|
string
|
|
|
When specified, keys whose in or out tangent type match the
specified type are preserved.
Supported tangent types:
fixed
linear
flat
smooth
step
clamped
plateau
stepnext
auto
This flag is only supported by the Key Reducer filter.
|
|
-sampleCount(-sc)
|
int
|
|
|
Defines the Gaussian filter kernel dimension.
|
|
-samplingRate(-sr)
|
float
|
|
|
Defines the rate at which keys are added to the Butterworth filtered curve in
frames per second (FPS).
|
|
-selectedKeys(-sk)
|
|
|
|
When specified, the filter is only applied to selected keys. This flag
supercedes the startTime/endTime specification.
|
|
-startTime(-s)
|
time
|
|
|
Specify the start time to filter. If not specified, then the first key in the
animation curve is used to get the start time.
|
|
-timeTolerance(-tto)
|
float
|
|
|
|
-tolerance(-tol)
|
float
|
|
|
|
-useQuaternion(-uq)
|
|
|
|
Enable to use quaternion instead of euler.
|
|
-width(-w)
|
time
|
|
|
Defines the width of the Gaussian filter.
