This project is now approximately 4.5k loc and has taken me 3+ months of development time..! Since it meets my "photography" needs as it is I decided to pause it once again to concentrate on other projects :P .. Overall it is pretty stable , useful and I have done a good job profiling code and taken performance seriously while building it... If someone wants a particular feature or has a bug fix , etc , you are welcome to add it on the issues tracker so that it may be added or fixed..

You can use the ./get-dependencies.sh script to get the required packages for compiling the project..!
Overall :
sudo apt-get install cmake git g++ gcc wx-common libwxgtk3.0-dev libalut0 libalut-dev freeglut3 freeglut3-dev libxxf86vm-dev libjpeg-dev libpng-dev libglew-dev imagemagick wget sed libnotify-bin
should give you everything you need to build this application using the CMake build system.
To compile the project open a terminal cd to the root of the project and run
mkdir build && cd build && cmake .. && make
if you want to install the app ( after compiling the project ) , run
cd build && sudo make install
your password is required..
This will add a shortcut on the applications list and the binaries flashyslideshowsgui and flashyslideshows on the system ..
./update_from_git.sh will download the latest version of the software from the master repository on github It also downloads AmmarServer which is an add on that enables a web interface for the application your password is required..
if you want to uninstall the app , run ./uninstall.sh your password is required..
Instead of the static app_clipart/backgroundN.jpg picture , the slideshow can draw its
background with a fragment shader. Press B to cycle through the ones that were found
at startup and back to the picture background , or pick one from the start with :
flashyslideshows -background aurora path/to/album
The ones that ship with the project are aurora , bokeh , gradient and plasma.
Every shaders/background_*.frag in the shaders
directory becomes a selectable background , so adding one is a matter of dropping a file
there , no recompiling involved. The files are
ShaderToy compatible : they contain a
mainImage(out vec4 fragColor,in vec2 fragCoord) and can use iResolution , iTime ,
iMouse , iDate and iChannel0..3 , so most single pass shaders from shadertoy.com
can be pasted in as they are.
ambient is a special one : instead of drawing a pattern it takes a heavily blurred ,
over-scaled copy of the photo the camera is on , so the background is coloured by the
album itself and cross fades whenever you move to another picture.
This needs a driver with GLSL 1.30 support. If there is none , or if the shaders directory is missing , the application says so and keeps using the picture background.
Transition mode 3 turns the slideshow into a full screen presentation : the photo you are on fills the window , and moving to the next one is carried by a fragment shader rather than by the camera. Whatever animated background is selected keeps showing in the bars either side of the picture.
flashyslideshows -t 3 -transition wipe -background ambient -play path/to/album
Press M until the transition mode comes round to it , and V to cycle through the
effects. The ones that ship are crossfade , dissolve , wipe and zoomblur.
Every shaders/transition_*.frag becomes a selectable effect , the same way the
backgrounds work. They may be written either in the ShaderToy dialect , or in the
GL Transitions one — a vec4 transition(vec2 uv) using
progress , ratio , getFromColor and getToColor — which is detected from the file
and wired up for you , so shaders from that collection can be dropped in unmodified.
Modes 0 to 2 are unchanged : 0 is the 3D seek through the album , 1 is an immediate jump and 2 is the transparency effect.
