Suppose that I have a closed boundary that is represented by nn
points. Using these nn
points I construct a polygon with nn
sides. I have a point P(x,y)P(x,y)
that islays inside the polygon.
I want to draw the normal from Point PP
to the edge/edges of polygon. Depending on the shape of the polygon, I can have multiple edges to which I can draw normalnormals from point PP
. How shall I select the subset of edges (from all edges of polygon) that can be chosen to draw normal from point P.P
?
