If you take one of those triangular architects rulers, lay it on a
table, put another ruler flat across the top, and rotate the
triangular one, you can visualize full-wave rectifying a floating
3-phase voltage source.

Half-wave, surely. FW gives you six peaks per cycle.

The rulers give you six peaks per cycle. You have to pay attention to the symmetry of the top and bottom of the triangle rotating between flat surfaces. I believe the peak occurs when a corner of the triangle is pointing to the side and the other two corners are in a vertical line. The troughs are when either flat surface is touching two corners.

Six diodes select the most positive and most negative wires of the
three. The output is analogous to the height of the ruler.

Probably a black Toblerone bar would work better. Or the box it came
in.

In a FADEC, three of the diodes are mosfets, three with grounded
source and common gate drive. When the rectified DC gets too high,
they turn on the fets and that shorts the source.
