DESCRIPTION
FractalNow is a command line tool that generates pictures of fractals as Portable PixMap (PPM) files.It is multi-threaded and implements advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.
See QFractalNow, a graphical tool to explore fractals.
OPTIONS
- -h
- Print help.
- -q
- Quiet mode, only errors are displayed.
- -v
- Verbose mode.
- -j <NbThreads>
- Specify number of threads (see help for default value).
- -g <GradientFile>
- Specify gradient file, overriding gradient from configuration/ rendering file.
- -l <FloatType>
-
Specify float type:
-
single Single precision.
double Double precision.
ldouble Long double precision.
mp Multiple precision.
-
single Single precision.
- -L <MPPrecision>
- Specify precision of Multiple Precision (MP) floats (see help for default value).
- -a <AntiAliasingMethod>
-
Specify anti-aliasing method:
-
none By default.
blur Gaussian blur.
oversampling Oversampling.
adaptive Smart oversampling.
-
none By default.
- -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).
-
Radius for blur (values in [2.5, 4] are generally good).
- -p <AAMThreshold>
- Threshold for adaptive anti-aliasing (see help for default value).
- -i <QuadSize>
-
Maximum size of quadrilaterals for linear interpolation.
-
Default is good for no visible loss of quality (see help for default value).
1 means no interpolation (all pixels are computed).
-
Default is good for no visible loss of quality (see help for default value).
- -t <Threshold>
-
Dissimilarity threshold for quad interpolation.
-
Default is good for no visible loss of quality (see help for default value).
A quadrilateral that shows too dissimilar values at its corners will be computed, as opposed to interpolated.
-
Default is good for no visible loss of quality (see help for default value).
