Apple provides a huge SDK for Iphone, with graphics library but Contour Lines of a function is a mathematical concept that is not likely to be integrated in any sdk that has no primary scientific purpose... But this is not really a problem, I also recoded the optimization Simulated Annealing to...

Thanks for the answer man, the expanding circle is a great idea ! And yes it's really only to make it look cool. And i don't think there are libraries for iphone that draw level sets of an arbitrary function... I'll try to use an animation and compute the new lines in a different thread to not...

Hi, Thank you a lot for your reply. Sorry I mixed up the terminology. What I called level lines is equipotential lines, i draw them by following the direction orthogonal to the local gravitational force. (Sorry for the confusion) That works well (check the pictures, the grey lines in...

Homework Statement Dear all, I have to find a fast way to compute changes in the level lines as the result of sudden changes in the local gravitational fields (2D space). (Caused by the destruction of a planet for example). I could recalculate everything but it takes too much time for the...
