Oooo... I finally get a chance to show the results of one of my filters 'in action'. haha But really: Here is a 3D rendering, where I used a map created with this filter to texture the floor.
(The wall texture was something I already had, and is a little too 'clean' to match the floor I guess... but this was just to show the map in use on a 3D object.)
It seemed like it took me forever to get this one to the point where I liked it, but now it has given me some ideas for another filter too, so I guess it was worth it.
