Mandelbrot set defined by a specific function
javascript,canvas,pseudocode,fractals,mandelbrot
Complex number have a two part: real, imaginary. So z = a + b*i, where a is real part, and b*i is imaginary. In provided sample for z=z^2+c, where z=z_r+z_i*i NOTE: i*i = -1 So z^2 = (z_r+z_i*i)*(z_r+z_i*i) = z_r*z_r+2*z_r*z_i*i + z_i*i*z_i*i = z_r*z_r+2*z_r*z_i*i - z_i*z_i now add c: z_r*z_r+2*z_r*z_i*i...
Mandelbrot set won't render correctly
Your complex number square is wrong. You are overwriting the old value of a where it is needed again in the computation of b. So save it in a temporary variable. Also, the bailout value of 60 iterations is rather small, 200 would be more appropriate for this scale, for...
extending mandelbrot to generate julia
The Mandelbrot set is a special set in terms of Julia sets, some documentation writes that the Mandelbrot set is the index set of ALL Julia sets (there is one and only one index set - the Mandelbrot - and there are infinite number of Julia sets.) When you calculate...
Drunk Mandelbrot implementation [closed]

Your calculation of the complex modulus is incorrect. float Complex::getAbsoluteValue() const { return sqrt(real * real + imaginary + imaginary); } You've since removed this section of your post, but it should say float Complex::getAbsoluteValue() const { return sqrt(real * real + imaginary * imaginary); } ...
Implementing a smooth color algorithm into my existing Mandelbrot generator
Your getIterValue needs to return an object containing the final value of Z as well as the number of iterations n. Your pseudo-code would then translate to nsmooth := iter.n + 1 - Math.log(Math.log(iter.Z.abs())/Math.log(2)) You can translate this to a value between 0 and 1 with nsmooth / maxIterations with...
C++ Mandelbrot program won't produce correct output
A good start with debugging is to run the program with simple inputs (e.g. to generate a 8x5 output image), then look at the output. Since PPM is easily human-readable, you'll see that you get only 8 samples. That should be a clue that the first row is okay, and...
I can't understantd something about mandelbrot fractal code
java,javascript,fractals,mandelbrot
I heard "escape" should be 4(2^2) Escape radius should be greater then 2 so any value > 2 is good. It can change shape of level sets and shape of numerical aproximation of Mandelbrot set. Square of escape radius should be greater then 4. See also this question HTH...
Multithreading computation of Mandelbrot set
c++,multithreading,fractals,mandelbrot
You're making this (quite a lot) harder than it needs to be. This is the sort of task to which OpenMP is almost perfectly suited. For this task it gives almost perfect scaling with a bare minimum of effort. I modified your draw_mandelbrot by inserting a pragma before the outer...
