distance between 2 polygon? about ruby-geometry

[xor256]

I thing about offset outside polygon. Minimal distance between alle edges to all edges other polygon. (i change image for clarify). offset is not this same shape.

How I can count distance between 2 edges?

[DanielVartanov]

You don't need a distance between edges, only distance between vertices (bounding boxes' edges are always parallel to axes).

[DanielVartanov]

@letarg0, well, just to re-iterate, Polygon#bounding_box seems to be a solution to your problem: since you apply this method to both polygons, you'll have just two rectangles each edge of which is parallel to one of axes, which makes the problem trivial since then

[DanielVartanov]

There is a function Polygon#bounding_box which is the most helpful to implement a function of such distance. Please let me know if it helps.

[letarg0]

What add offset to Polygon_2 ? Any code with Kernel Point?

[DanielVartanov]

Sorry, I didn't get your question, could you please change its formulation somehow? Thanks in advance

[letarg0]

@DanielVartanov Please look at image. I have B shape, How get shape around B shape. Bigest , lighter shapes.

this is not a rectangle

[DanielVartanov]

Again, let me repeat: when you apply a method of Polygon#bounding_box to a second polygon labeled 'B', you will have a rectangle. Please see how Polygon#bounding_box works.

canYou show me a code or draw a image?
I dont know what I canthing about Yours sugestions.
