Subject: Plotting lines between two polygons
Hello Mr. Fanning,
I tried to post the following message to the
"comp.lang.idl-pvwave" newsgroup, but it didn't work. I
was hoping that you would know the answer or else would
you post this question for me?
I would like to plot lines between polygons using
object graphics.
When creating the polygons there is no trouble. The
coordinates used
to define the polygons (circles) can be used to define
the lines.
One of the circles has to be rotated/translated
interactively. This circle has it's own IDLgrModel as
conatiner. This container and the polygon that is
static are together with the lines in another
container.
Can anybody tell me how to retrieve/compute the new
coordinates for the line after a rotation/translation
of the polygon?
Thanks.
Marco
