i got one question though, don't know if it's off topic or even discussed before:there's a mismatch between the actal and the displayed framerate.the viewer displays more than 60fps, but obviously, when the scale value is low,i get down to 1fps
That's a product of the filter -- Since it's dealing with individual pixels (and not subpixels), many input values will provide the same output image (making it look low framerate).
If you want it to step more smoothly, you'll have to operate on a larger image, and downsample it before display (my composition intentionally avoided this because the request was for a mosaic without bilinear filtering on output)
If you add something else to the composition (a rotating teapot, for example), you'll see that it's really running at close to the indicated framerate. If it's not, then either your machine can't handle rendering the filter in real time (ancient mac?) or there's some other weird bug taking place.
