But the problem is that very few of the photoshop filters "wrap", meaning if you want a filter to wrap through the parameter space, you have to run the filter on a portion of the image, offset, and then mask and filter on the other part, knitting them back together manually. (A bit of a pain.) Included are some images I made. The original, then: twirl1: a wrapped motion blur at some random angle. (small discontinuity because I was sloppy) twirl2: same with offset in the y (=r) direction twirl3: same with offset in the x (=theta) direction -- I really like this one. So, it's making lots of sense to combine the KPT twirl (because we can do much cooler ones) with the polar stuff Chris wants to do. comments? mike
