NAME¶

evolvotron_render - Render an evolvotron function tree to an image.

SYNOPSIS¶

evolvotron_render [options] imagefile.[png|ppm]

DESCRIPTION¶

evolvotron_render reads an evolvotron image function from its standard input and renders it to an image in the file specified (suffix determines type, defaults to ppm if not recognised).

Image functions can be obtained by saving them from the evolvotron application, or using evolvotron_mutate.

See the evolvotron manual (accessible from the evolvotron application's Help menu) for more information on image functions.

COMMAND-LINE OPTIONS¶

-f, --frames

frames Generates multi-frame animations. .fnnnnnn is inserted into the specified filename (before the filetype suffix, if any). You can use this on functions which weren't evolved in animation mode, but there's no guarantee they have any interesting time/z variation.

-h, --help

Display a summary of command-line options and exit.

-j, --jitter

Enable sample jittering.

-m, --multisample

multisample Enables antialiased rendering. This specifies the size of the sub-pixel sampling grid, so 1 provides the default one-sample-per-pixel behaviour, while 4 provides 16 samples per pixel on a 4x4 grid. Unlike the main evolvotron application, there is no upper limit, but of course rendering time increases as the square of this number.

-o, --output

imagefile.[ppm|png] This option is an alternative to specifying the output filename as a positional argument.

-s, --size

widthxheight Specify resolution of output image. Defaults to 512x512.

-v, --verbose

Verbose mode; useful for monitoring progress of large renders.

EXAMPLES¶

evolvotron_mutate -g | evolvotron_render -s 1024x1024 function.ppm
