Do you know of any good 2D smoothing algorithms? I implemented the
basic algorithm, but when I added the matrices together I got cross
hatch lines at the "harmonic" boundaries. I tried offsetting the
overlaps, as well as waiting to smooth the noise until later in the
process, but neither idea worked.
Off the cuff, have you tried either scaling down the pic by 50%, or
conversely scaling it up 200%? The scaling should result in a smoother
image.
Another idea would be to implement a simple blur algorithm used for
fire: average the color of number of pixels around the target pixel
together. See
<http://www.gamedev.net/reference/articles/article222.asp> for a simple
fire algorithm using blur.
