Mandulia

Mandelbrot/Julia set explorer.

Invocation

Multi-core CPU with lots of RAM recommended:

mandulia configuration

Currently there is one preset configurations available: 'main' -- keyboard navigation with randomized attract mode.

To render videos (see below):

mandulia configuration |
ppmtoy4m -S444 -F25:1 |
ffmpeg2theora -v 8 -f yuv4mpegpipe -o mandulia.ogv -

Controls

'main' defines the following key bindings:

Escape -- quit F11 -- toggle full screen a -- enter attract mode immediately r -- record for 10 minutes (assuming 25fps) s -- record for 1 frame (aka screenshot)

Note that recording is via PPM images on 'stdout', so to avoid flooding your terminal with binary data be sure to redirect it somewhere else.

As a side-effect, the following count as 'activity':

PageUp -- zoom in PageDown -- zoom out cursors -- move around End -- stop moving Home -- return to base [ ] -- change speed

-- reset speed

{ } -- change weight ~ -- reset weight

Attract mode is entered after 1 minute (assuming 25fps) of inactivity, and left on any activity.

Other configurations may differ, check their sources for details.

Scripting

Mandulia can be reconfigured without recompilation, using Lua scripts. The first (non RTS) argument to 'mandulia' will be executed on startup. First it will try to load it as a file, then via Lua's 'require()'. See 'defaults.lua' to see the available interface, and 'main.lua' for an example of keyboard navigation. Note that some variables only take effect on startup, and later modification will be ignored.
