Extensional Tectonics with Planck.js
While working with stratigraphic layering of planck.js bodies that I called "particles", I saw some interesting behavior that looked like classic structural models of extensional faulting. I decided to try for this explicitly...
It is January, 2026, BTW. I have taken about a year and a half off from coding, after getting to a basic riderless downhill bike in PlanckBike I started creating stratified particles on my way toward sediment transport but the behavior I saw in planckBasic.htm stimulated me to try this sidetrack.
