resample: QTS Resampling

Description

This function performs uniform resampling using SLERP.

Usage

resample(x, tmin = NA, tmax = NA, nout = 0L, disable_normalization = FALSE)
# S3 method for qts
resample(x, tmin = NA, tmax = NA, nout = 0L, disable_normalization = FALSE)
# S3 method for qts_sample
resample(x, tmin = NA, tmax = NA, nout = 0L, disable_normalization = FALSE)

Value

An object of the same class as the input argument x in which quaternions are uniformly sampled in the range [tmin, tmax].

Arguments

x

An object of class qts or qts_sample.

tmin

A numeric value specifying the lower bound of the time interval over which uniform resampling should take place. It must satisfy tmin >= min(qts$time). Defaults to NA in which case it is set to min(qts$time).

tmax

A numeric value specifying the upper bound of the time interval over which uniform resampling should take place. It must satisfy tmax <= max(qts$time). Defaults to NA in which case it is set to max(qts$time).

nout

An integer specifying the size of the uniform grid for time resampling. Defaults to 0L in which case it uses the same grid size as the input QTS.

disable_normalization

A boolean specifying whether quaternion normalization should be disabled. Defaults to FALSE in which case the function makes sure that quaternions are normalized prior to performing SLERP interpolation.
