# Implements the zip_curve_tuples method
module Tracksperanto::ZipTuples
# Zip arrays of "value at" tuples into an array of "values at" tuples.
# The first value of each tuple will be the frame number
# and keyframes which are not present in all arrays will be discarded. For example:
#
# zip_curve_tuples( [[0, 12], [1, 23]], [[1, 12]]) #=> [[1, 23, 12]]
#
def zip_curve_tuples(*curves)
tuples = []
curves.each do | curve |
curve.each do | keyframe |
frame, value = keyframe
tuples[frame] ? tuples[frame].push(value) : (tuples[frame] = [frame, value])
end
end
tuples.compact.reject{|e| e.length < (curves.length + 1) }
end
end
