THINGS TO TRY
Rotate and Zoom in 3D
Slider Zoom
Gamepad Controls
Automatic Animation
SNAPSHOTS
DETAILS
The averaging operation is represented in the code by a matrix.
Snapshot 1: the initial state of 20 2D points
Snapshot 2: the final state of the 20 2D points
Snapshot 3: the middle state of 30 3D points
