About this video

This video explores weighted averages of three points, where each point is given a weight that controls how strongly it pulls the result. It ends by returning to the interactive replacement curves, where these weighted averages will be used in subdivision. (Only the final lines of the transcript are available.)

You'll be able to

  • explain what a weighted average of three points is.
  • tell which point has the most influence from its weight.

Key words

weighted average
An average where each value is multiplied by a weight, so some values count more than others.
weight
A number that says how much a point counts in a weighted average.
Transcript
