Another option: use my LineGeneralization class www.motiondraw.com/md/as_samples/drawing/lineGeneralizationDemo/demo.html
An excellent explanation/visualisation of the implemented algos - Lang Simplification and McMaster's Slide Averaging Algorithm - is found at http://www.sli.unimelb.edu.au/gisweb/LGmodule/LGSelect.htm (thanks to Jim Cheng) What is still missing in this context is a good AS spline function: feed in an arbitrary number of points, get back - reasonably fast... - a number of quadratic bezier curves that connect the points in an elegant way. This would allow to reduce the number of points drastically while still getting visually acceptable results (as you'll see, I'm using a over-simplistic approach in the demo to draw the 'pseudo-spline' which will not always produce elegant results...) For math buffs: Jim Fitzsimmons has several interesting-looking articles on Bézier Curves http://www.tinaja.com/third01.asp which might be helpful (not for me though - that's _far_ beyond me...) But I guess that it's not so much about mathematical precision as about finding an approximation that is fast enough to be processed by Flash... Martin? Helen? How about reviving the good ol' hardcore Math/Trig sessions on flashcoders? :-) HTH -------------- Andreas Weber motiondraw.com _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
