Change the shape of a set of points
How to change the form of a shape by stretching it out in different
directions, without the perimeter changing? take a piece of string with
both ends connected as an example, it would form a shape resembling a
circle, if one side is pushed in or out, only the shape will change, but
the perimeter and area will stay the same. Im trying to accomplish
something almost if not identical to this.
I am not sure if I am being very clear with my question, please let me
know if it needs to be given more detail. Any help would be appreciated.
Even though this is needed for an application written in objective-c, code
in C, C++, or C# will also be of help.
