Another useful option can be added for the background image; "Wallpaper mode" to use a lightmap tiled (like a plain wallpaper) as a background. If liked it can be very cool to use two tiled maps instead of the "depth" colours as an infinite double plane.
I wrote a coloring algorithm for UltraFractal for tiled images. Don't know if you can find it useful?
Image {
;
; Image just displays an image from disk. It's best used on the Outside tab,
; together with the Pixel formula from Standard.ufm.
; TOO BAD, the standard "Image" don't have wrapping an I had
; to rewrite it...
;
global:
Image i = new @imageParam
Image q = new Image
final:
; Use #pixel as the complex coordinate inside the image, but scale such that
; the default corner coordinates (-2,1.5)..(2,-1.5) correspond to the entire
; image width.
float v = 0.5
complex c = v * #pixel
float w = 0
float h = 0
float w1 = 0
float h1 = 0
; Make sure the ratio of the image is preserved.
float ratio
if !i.getEmpty()
w = i.getWidth()
h = i.getHeight()
ratio = w / h
else
ratio = 1
endif
w1 = real(c) - round(real(v*c))/v
h1 = imag(c* ratio) - round(imag(v*c* ratio))/v
#color = i.getColor(w1 + flip(h1))
default:
title = "Image (wrapped)"
helpfile = "Uf*.chm"
helptopic = "Html/coloring/standard/image.html"
heading
text = "Tip: the Image coloring algorithm works best with the standard \
Pixel fractal formula. This wrapped version is strongly reccomended \
to deal with any magnification, mapping!"
endheading
Image param imageParam
caption = "Image"
hint = "The image selected here will fill the entire layer, if combined \
with the Pixel fractal formula and if the location is set to the \
default. To do this, click the Reset button on the Location tab."
endparam
}
This image was made with UF using two maps and the 3D mapping, as a sample
This is not a begging post, only a stupid idea!
