Okay, I think I found my solution conceptually...but coding it is the tricky part.
I have a drawing, 2d, of a "box." Not a geometric box but a "box" that will be built which may not be of uniform size D ___ ______ C | |____| | | | | ____| B A |________| Thats just an example. So what I do is grab my four bounding points. Bottom left is the point with the smallest x with smallest y. Bottom right is point with largest x with smallest y. Top right is largest x with largest y. Top left is largest y with smallest x. Now to get the bottom perimeter I need to sort my points between A nd B where X is stil increasing up to that point. Then B to C where Y is increasing, then C to D where X is decreasing then whats left over in Y descending order. We will be using an AutoCAD program that will draw a line between each point (not just A,B,C,D but all points). So if I can sort in this counter clockwise order then I have a vector where I draw a lin from Ai to Ai+1. The trick is how to code? Any suggestions, data structures etc? Thanks! Have fun! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
