pymel.core.animation.filterCurve

filterCurve(*args, **kwargs)

The filterCurve command takes a list of anim curve and filters them. Currently only a Euler filter is supported. The Euler filter demangles discontinous rotation anim curves into smooth curves.

Flags:

Long name (short name)		Argument Types	Properties
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.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
filter (f)		unicode
	Specifies the filter type to use. The avalible filters are euler, simplify, and resample. By default euler is used.
kernel (ker)		unicode
	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.

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.
maxTimeStep (mxs)		float
	Simplify filter.
minTimeStep (mns)		float
	Simplify filter.
period (per)		float
	Resample filter
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
	Simplify filter.
tolerance (tol)		float
	Simplify filter.

Derived from mel command maya.cmds.filterCurve

Example:

import pymel.core as pm

import maya.cmds as cmds

pm.filterCurve( 'nurbsCone1_rotateX', 'nurbsCone1_rotateY', 'nurbsCone1_rotateZ' )
