I was thinking of the different parts from the original code.

Why is the [display] needed, when normal plot functions just plots without need of 'display(>plotname<)'?

Why is it important to write (v,u) and not (u,v). I discovered, that a different plot appears.

Not that it is a problem to write it in that sequence.

Seemed to me, that it was implemented, that u ranges from 0 to 1,

and v from 0 to 2*Pi in [(1+u)*cos(v), (1+u)*sin(v)], is this not correct?

 I cannot see, why there is a second plot parenthesis, and what '1' and 'x=0..2*Pi' does in the code

(plot(1, x=0..2*Pi, filled=true, colour=cyan)). I've tried removing the 'x=0..2*Pi' and the plot still works.

The rest of the code is understandable.

Once again, thank you!

This all look very nice, and indeed the plane I was searching for was created. Thank you!

But would you care to explain the code in itself, so I can construct future planes with this method?
