I need to come up with a convex hull algorithm t开发者_C百科o read through a bunch of X , Y co-ordinates and outline the image..
i'm coding in python
Any ideas?
Are there any more details or constraints to your question? After searching wikipedia for "Convex hull algorithms", it gave me a list of algorithms, of which I clicked "Monotone Chain"
