Programming Challenge 10/22

A bottle of Walker Black to anyone who can programmatically convert a straight polyline segment to one having only one radius, which is less than half the chord.  No, you may not add vertices.

I dont think you can have less than 1/2 the length of the straight segment once you go less the arc does not go through the two segment points, could move those 2 points by like 1e-10 which would not in a sense reveal a change in the segment lengths and the radius would appear to be 1/2 segment length. Pretty easy to program.

Happy for some one to say I am wrong

Polyline bulges

Yeah, and while you're at it, draw a Circle whose radius is less than half its diameter.

@john.uhden I've always liked this code from master ElpanovEvgeniy.

Since a single arc cannot be created between two points with a radius less than half the distance between the two points the answer to the question must lie in a closer examination of the question wording.   It is noted that the word "arc" never appears in the question.   A look at the DXF codes for a "polyline" indicate the possibility that perhaps a solution may be possible if a spline fit was considered but what would that imply about a radius?  Still, no solution in site.  We could then turn to the bottle of Walker Black.  Ah, I think there's where the solution lies!  Consuming the bottle would make all things possible.    Happy holidays!

You only "don't think?"

@hak_vz 

Thanks, Hak.  I had no idea!

Ah, grread.  I've been meaning to add that for decades.

Too bad that Jason Bourne had to extirpate him.
