Barycentric Etch-A-Sketch

Chris Tralie

In the GUI below, choose three points in the plane the plane (z = 0) to test make a triangle. Left click to select the points, and right click to delete the most recently selected point. Then, adjust the sliders on the right to take different vector weighted averages of the three triangle points.

NOTE: This GUI runs in the plane for simplicity (all z coordinates are zero), but the same phenomenon will happen in 3D.
