Dear lazyweb, I have a question with regard to image manipulation. Given an rectangle image with a continous function on it (in my case, walking distance from a certain point), I can easily draw the contour lines of the function, i.e. for a given distance from the center mark all points that have this distance. This looks very similar to the contour lines of height map. I’d like to morph this image now that all these contour lines are circles around the centers, but I don’t have a good idea how to do that with a minimum amount of distorting. Any suggestions or pointers to algorithms are welcome.
