Port of frei0r to the Futhark programming language
fut0r is a port of the frei0r effects library into the Futhark programming language.
You can use it either as a Futhark package or a drop-in replacement for frei0r.
Only a few effects have been ported. Feel free to port some more! Try to follow the structure of the existing effect ports.
Run:
futhark-pkg add github.com/nqpz/fut0r
futhark-pkg sync
Example use:
$ futharki
> import "/futlib/array"
> import "lib/github.com/nqpz/fut0r/effects"
> let (h, s, l) = (0.1f64, 0.7f64, 0.5f64)
let grey_image = replicate 16 (replicate 16 0xff999999)
in colorize h s l grey_image
Run:
git clone git@github.com:nqpz/fut0r.git
git submodule update --init
(cd frei0r && cmake . && make) # Check frei0r/INSTALL for dependencies
make
This will build frei0r.h-compatible .so files for all Futhark effects. This can be used with programs like ffmpeg and Kdenlive, although it hasn't really been tested.
This will also build docs for the Futhark filters.
Run make test to test that the Futhark ports return the same image as
the original plugin. It generates a random image with random parameter
values, passes it to both the original frei0r plugin and the new
Futhark-using plugin, and compares the two outputs.
See https://github.com/dyne/frei0r/blob/master/AUTHORS for a list of the original plugin authors.
