Impossible to draw a vertical polygon ?

[kyonn]

Take 3 points or more which are on the same path line and give them
different altitudes, and you will expect to draw a "vertical polygon"
on Earth.

But ge does not render it.

In fact I'm searching for an "extrude alternative without having to
draw from the ground to the points"

Any guru suggestion ? Or is that regular considering geplugin api, so
that I would have post this in the Feature Request section ?

Does the relative-to-ground example not work?

[kyonn]

No I figure because a point can only be extruded to the terrain or sea
floor, and not to another point above (or beneath) the terrain of sea
floor.

Take a couple of points with the same latitude & longitude but not the
same altitude, and another couple of points on the same geodetic path
with arbitrary altitude : ge won't render this "vertical polygon"

wouldn't two points (or any number of points) at the same lat/long
with different altitudes be a vertical line, not a polygon?
It would be interesting to see how a polygon with zero area (a line)
renders in ge at any orientation - that may be your problem?

[kyonn]

Well not really. I encountered this problem : a polygon which is
absolutely vertical is not rendered by ge !

It could be a nice way to stop an extrude before the terrain altitude.

May I request this feature ?

Really, they will be a vertical line (a 1-dimensional shape), not a
polygon (2-dimensional shape).
Try drawing it as a linestring instead.
