Calculates the average (mean) of the values received by this node so far.
The 1st item in Averages
is the average of the current 1st item in Values
and the 1st item in previous Values
lists; the 2nd item in Averages
corresponds to the 2nd item in Values
; and so on.
Values
— When this port receives an event, each list item is averaged in with the previous values of that list item.Lookback
— The number of previous values to include in the average.
Values
list and the 10 previous Values
lists.Values
.Auto
, the average includes all previous Values
in its history.Reset
— When this port receives an event, the node’s history is cleared. It forgets about all previous Values
and begins calculating the average anew with the next Values
.If an event hits both Values
and Reset
, then the history is reset before the average is recalculated. In other words, the node outputs Values
.
If you increase Lookback
from A to B while the composition is running, then the next event to Values
will calculate the average based on Values
and the previous A values in its history.
For point types, this node averages each component (X, Y, Z, W) of the points separately.
Thanks to Karl Henkel for developing the node this is based on.
