FRACTALNOW(1)

💖 FRACTALNOW 💖

okay bestie, gather round, because this one is literally fractals and it is giving main character energy 👑

fractalnow — generate fractal images. that's it, that's the vibe ✨

🌸 SYNOPSYS 🌸

fractalnow [OPTIONS] -c <Config> [-x <Width>|-y <Height>] -o <Output>
fractalnow [OPTIONS] -f <Fractal> -r <Rendering> [-x <Width>|-y
<Height>] -o <Output>

two ways in, bestie: either you hand it a <Config> with -c, or you hand it a <Fractal> with -f and a <Rendering> with -r. either way you're picking a size with -x <Width> or -y <Height>, and you are always telling it where to put the art with -o <Output> 🎨

🦋 DESCRIPTION 🦋

FractalNow is a command line tool that generates pictures of fractals as Portable PixMap (PPM) files. periodt. 🖼️

It is multi-threaded and it implements advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators. like, the way it just goes? no cap, it's quick ⚡

also: go check out QFractalNow, a graphical tool to explore fractals 👀 (that's your visual-girlie option, iykyk)

✨ OPTIONS ✨

• -h — print help. your little "what do i do" bestie 🫶
• -q — quiet mode: only errors are displayed. minimalism, but make it terminal 💅
• -v — verbose mode. it will tell you everything, and honestly? love that for us 📣
• -j <NbThreads> — specify number of threads. (peep the help for the default value 👀)
• -g <GradientFile> — specify gradient file, overriding the gradient from the configuration/rendering file. so like, this wins 🏆
• -l <FloatType> — specify float type:
  • single — single precision.
  • double — double precision.
  • ldouble — long double precision.
  • mp — multiple precision.
• -L <MPPrecision> — specify precision of Multiple Precision (MP) floats. (check the help for the default value 💖)
• -a <AntiAliasingMethod> — specify anti-aliasing method:
  • none — by default.
  • blur — Gaussian blur.
  • oversampling — oversampling.
  • adaptive — smart oversampling. 🧠
• -s <AAMSize> — specify size for anti-aliasing:
  • Radius for blur — values in [2.5, 4] are generally good.
  • Scale factor for oversampling — [3, 5] is good for a high quality image.
  • Scale factor for adaptive — integers between 3-5 are good for a high quality image.
• -p <AAMThreshold> — threshold for adaptive anti-aliasing. (the help has the default value, bestie 🎀)
• -i <QuadSize> — maximum size of quadrilaterals for linear interpolation. the default is good for no visible loss of quality (yes, the help has the default value too 💜). and heads up: 1 means no interpolation — all pixels are computed. every single one. 😭
• -t <Threshold> — dissimilarity threshold for quad interpolation. default is good for no visible loss of quality (help → default value, you know the drill 🌸). a quadrilateral that shows too dissimilar values at its corners will be computed, as opposed to interpolated. it's giving "we tried to skip it and it said no" 💀
