As requested by Barry-H:

A simple node assemblage, to create an egg outline.
This is just a collection of pre-existing nodes, with the trigonometry formulas which create the "egg shape", not a new .js node program.

U is run from minus PI to plus PI, for full egg.
Change minus PI to 0 for half egg, or trim full egg.
U num for the number of Points is set at 500.

I noticed that the sliders do not have a reset to defaults.

Also, the curve always appears as style RED.
