Another multifractal spectrum of the same fractal flame as before. This time it's f(alpha) vs alpha instead of D(Q) vs Q.
A cluster of lines start near (1.5, 1.4) and get closer to each other as they increase (progressively more slowly) towards (2,2).
Added EXR import to my #MultifractalSpectrum calculator. Hacked an option into #Fractorium command line renderer to output raw histogram data to EXR. Ran a batch process to render and analyze some of the examples that come with Fractorium (in its Data/Bench directory).
The f(q) vs a(q) curves look a bit crisper with this method.
And calculating D(q) is easy, just
$$D = (a * Q - f) / (Q - 1)$$
I ported the linear regression to OpenCL too, now only input and output needs to run on the CPU, GPU does all the calculations.
Some of the test histograms I'm using give bizarro curves though, not sure what's up - bizarro with two different algorithms means it's probably (?) a real behaviour?
