darktable which sucks less

this is an experimental complete rewrite of darktable, naturally at this point with a heavily reduced feature set.

the processing pipeline has been rewritten as a generic node graph (dag) which supports multiple inputs and multiple outputs. all processing is done in glsl shaders/vulkan. this facilitates potentially heavy duty computational photography tasks, for instance aligning multiple raw files and merging them before further processing, as well as outputting many intermediate results as jpg for debugging. the gui profits from this scheme as well and can display textures while they are still on gpu and output the data to multiple targets, such as the main view and histograms.

features

• very fast GPU only processing
• general DAG of processing operations, featuring multiple inputs and outputs and feedback connectors for animation/iteration
• full window colour management
• minimal set of image operation modules
• noise profiling
• minimally invasive image database

build instructions

you should have checked out this repo recursively. if not, do

git submodule init
git submodule update

to grab the dependencies in the ext/ folder. you should then be able to simply run 'make' from the bin/ folder. for debug builds (which enable the vulkan validation layers, so you need to have them installed), try

cd bin/
make debug -j12

simply run make without the debug for a release build. make sanitize is supported to switch on the address sanitizer. changes to the compiled used can be set in config.mk. if you don't have that file yet, copy it from config.mk.example.

running

the binaries are currently wired to run from the bin/ directory:

cd bin/
./vkdt -d all /path/to/your/rawfile.raw

note that you have to edit the filename in the example cfg to point to a file that actually exists on your system. if you run the command line interface 'vkdt-cli', it will replace all 'display' nodes by 'export' nodes.

licence

our code is licenced under the 2-clause bsd licence (if not clearly marked otherwise in the respective source files). there are parts from other libraries that are licenced differently. in particular:

rawspeed: LGPLv2 imgui: MIT

and we may link to some others, too.

dependencies

• vulkan, glslangValidator (libvulkan-dev, glslang-tools, or use the sdk)
• glfw (libglfw3-dev)
• submodule imgui
• submodule rawspeed (deponds on pugixml, stdc++, zlib, jpeg, libomp-dev)
• libjpeg
• build: make, pkg-config

optional (configure in bin/config.mk):

• freetype (libfreetype-dev)
• exiv2 (libexiv2-dev)

faq

• can i run my super long running kernel without timeout? if you're using your only gpu in the system, you'll need to run without xorg, straight from a tty console. this means you'll only be able to use the command line interface vkdt-cli. we force a timeout, too, but it's something like 16 minutes. let us know if you run into this..
