Synopsis

filter -t filterType [-n name]
filter -edit ... filterNode
filter -query ... filterNode

Creates or modifies a filter node. Filter nodes are used by applyTake to modify recorded device data before assigning it to the param curves for the attached attributes.

Return value

Creation Flags

-type (-t) string
Filter type to create, One of:
filterEuler Euler angle "demangler"
filterResample Resamples input data at fixed output rate with several filtering options
filterSimplify Combines groups of data points that are almost linear into lines segments
filterClosestSample Resamples input data a fixed output rate using the closest sample point
-name (-n) string
Name for created filter

Edit/Query Flags:

filterEuler Flags:

-smooth (-s) int
Set the the Euler demangling operation to one of:
