I guess stardust requested this after I asked a question about this.
Very usefull!

Very Nice video! Speaking of the Burning Ship, I don't know if you have already explored the other two (made by not folding all variables).. replacing the ship abs function (in fractint and ultrafractal formats): z=abs(real(z))+flip(abs(imag(z))) by z=abs(real(z))flip(imag(z)) or by z=real(z)+flip(abs(imag(z))) They both create very interesting sets to explore (in special in the mirror spiral department).. Also, try the Quadray Burning ship, using the abs on the Quadray set.. I call that one, the Burning Fish because ilooks like that. There's another, but in the Nova formula (the newton iteration).. but that's another history..

ok, i might visualise them as spin offs, folding justx and justx, will check it

yay, i saw it, the "+" does not look very interesting, although it is fractal i am thinking how to incorporate it in the tutorial, perhaps i include them as spin offs, for the negative multiplication by1 i need to adjust my visuals because it is a rotation around the x axis and not a fold although it could be visualised as fold it would look weird to fold opposite side against eachother

though, i wonder why the heck arent they the same? the abs should render the negation obsolete

woah, the julias are quite cool, this is the julia z=abs(real(z))+flip((imag(z))) z=z^2+c BUT, for the julia i am preparing a special issue explaining the difference julia/mandelbrot method, which makes crystal clear why the mandelbrot pops out, you might have recognised the mandelbrot tutorial is not finished and it started from back (4.4) in issue 4.3 i want to point out the difference (different starting location, same addition for every point, mandelbrot set is a map of julias that are connected )

Actually I consider these sets some sort of halfway between both the Burning Ship and the Mandelbrot set because they share the properties of both.. The Julias reflects this property very well (in special of the julias of the spiral kind) Here are two images, one little zoomed area of one of the mandelbrot and a julia set. woah, the julias are quite cool, this is the julia z=abs(real(z))+flip((imag(z))) z=z^2+c BUT, for the julia i am preparing a special issue explaining the difference julia/mandelbrot method, which makes crystal clear why the mandelbrot pops out, you might have recognised the mandelbrot tutorial is not finished and it started from back (4.4) in issue 4.3 i want to point out the difference (different starting location, same addition for every point, mandelbrot set is a map of julias that are connected ) Oh.. the relationship between the Mandebrot and Julia becomes complicated when you use perturbations (different starting points).. They are often overlooked, but they can generate very interesting images if you use them in a dynamic way..

abs(x) and abs(x) aren't the same! right, but in both formulas the abs is outside, abs(x) and abs(x) should be the same ...

Hmm.. no.. look again (Fractint format can be a little tricky): z=abs(real(z))flip(imag(z)) and z=real(z)+flip(abs(imag(z))) In a more formal way: z=Complex( abs(zr), zi ) and z=Complex( zr, abs(zi) )

There it is. Many thanks Christian! Funny how the most interesting quadrant is the one where all the points get folded out of. The translation is again beautiful to watch! A suprise is the resulting smoothness of the inner structures. I see more curved lines than sharp folds, so it might approach analytical math in some properties.
