A_5 Transition - Pair of aligned ridges

A_5 Transition
(after Bogaevski)

Illustration

We illustrate the transition with a tubular shape, which is deformed such that two ridges, one from each end pass near each other parallelwise, near the center of the tube.

**BEFORE transition**


Tube with ridges (14400 point generators).

**AT/NEAR transition**


Tube with ridges (14400 point generators).

**AFTER transition**


Tube with ridges (14400 point generators).
