 grin Wouldn't it be lovely if there is a batch facility with Mandelbulber as it takes typically five minutes to generate a 1920 x1080 image. Dozens of images could then be batched overnight. If there are any further speedups for the program it would make the program even better. Keep up the good work on this brilliant program.

I'm not sure if I understand well what you mean writing "batch facility". Mandelbulber can be started from DOS shell (or Linux terminal) with following parameters:

mandelbulber [options...] [settings_file]
  -nogui          - start program without GUI
  -flight         - render flight animation
  -keyframe       - render keyframe animation
  -start N        - start renderig from frame number N
  -end            - rendering will end on frame number N
  -format FORMAT  - image output format
     jpg - JPEG format
     png - PNG format
     png16 - 16-bit PNG format
     png16alpha - 16-bit PNG with alpha channel format
[settings_file] - file with fractal settings (program also tries
to find file in ./mandelbulber/settings directory)
When settings_file is put as command argument then program will start in noGUI mode

For example:
mandelbulber -format png16 "Hybrid 1.fract"
will render fractal image defined in "Hybrid 1.fract" settings file located in ./mandelbulber/settings folder and save image in PNG 16-bit format in folder defined in given settings file.

If you want to make some batch rendering you can write some simple script in .BAT file or bash script on Linux.

Now it is open topic. Maybe somebody is interested in writing some simple program for managing batch process.

I'm currently also looking for a way to calculate lots of settings with Mandelbulber (on windows) and came across a similair description. But at least with v2.05, it seems any command line parameter gets ignored.
Also, scanning the source (main.cpp), i see nothing (really) referring to the command line parameters.

Any hints welcome.

hi arnie, welcome to the forum  grin

mandelbulber will get a vast cli interface in 2.0.6
take a look at the current codebase at github, especially:
this gives you a good idea what to expect.

i think what paolo means by "batching" is exactly the queue system what will also come with 2.0.6:
you have a list of settings files which will be processed one by one.
you can also specify multiple fract files on the command line, which get thrown into the queue and processed.
or a whole folder, which gets searched for fract files, the fract files pushed to the queue, and the queue rendered.

btw: development is now in feature freeze and bug hunting.
i think next release can be expected in 1 - 3 weeks?
