Actionscript :: Assemble Array Of Continuous Points For A Contour Line Using Conrec

I am trying to implement contour lines in ActionScript using Conrec. I have looked at both the java and javascript implementation and am still stuck.URL...Conrec will take grid data and assemble continuous contour lines. The problem is that it does not necessarily draw those lines in a continuous fashion. For example, it will draw A->B and then C->B and then C->D instead of A, B, C, D, etc.The javascript implementation seems to be accounting for this and serializing the instructions into an array of draw points. Which is what I too want to accomplish in the end. That is it takes the instructions from the core Conrec logic (eg: A->B, C->B, C->D, etc) and organizes it into an A, B, C, D series. I think it will also return the series as a multi-dimensional array to accommodate broken lines (eg: [[A, B, C, D], [E, F, G]]). This last functionality is what I need to do in Actionscript.This last part is where I am stuck. Ignore Conrec for now (I have given up on finding an Actionscript implementation), how can I organize these instructions into a collection of serial points? When Conrec gives me "draw point from X->Y" how can I first check if X or Y are already in a series and append either X or Y (whichever is not in the series) into the series? AND if neither are in the series, start a NEW series with X, Y as the starting set. Then check subsequent instructions against all existing series and connect series if they now start and stop on the same point? Also, I need to be able to allow for a series to close itself (eg: A, B, C, A) -- a loop (is that even possible?!).

I'm not sure if there is a technical term for what I want to do beyond "concatenation". I also hope someone out there has done this with Conrec and can give me some pointers.In the meantime, I am going to continue to plug away at this and see if I can come up with something but I am not confident in my abilities.If you know another way to draw contour lines from grid data, I am open to alternatives. But I have to be able to implement it in Actionscript.
