Introduction
-------------
This work is only a sort of experiment. A challenge with myself to see what and how much I know about the GPL programming world.
I would like to say it's a test to demonstrate to myself my skillness with the art of GPL editing.
But, since I'm a computer graphics enthusiast too, I also tryed to give all this a sense and a purpose.
I got the idea behind this work watching the Barchetta's GPL Reflector movie. In it he used that wide and undefined white space to show the GPLEA cars, such as in the "Construct Program" of The Matrix movie, a large and vague landscape to drive shapes into.
So what's this?
----------------
Chroma Key is a free space working environment for GPL that makes simple the bluescreen and chromakey compositing processes. It allows movie-makers, computer artists and developers to have a monochromatic stage to easily perform cutting operations as well as blending and other compositing techniques.
How does it works?
---------------------
Chroma Key is installed as a standard track in GPL.
Loading it, you'll have a wide and opened free space (9424 km^2) to make whatever you want with your favourite car. Then you'll be able to take a screenshot and have a fresh image (without any kind of environment) with which perform a chromakey compositing process and overlap any kind of landscape.
Obviously video compositions are allowed as well. Using the Camera Control Master by Peter van der Burg (and a video capture program) you can obtain a source that can be easily filtered and precisely overlapped to another existing video.
Coloured Workspaces
-------------------------
The default workspace colour of Chroma Key is the pure white (255, 255, 255), but obviously you can freely change this colour according with your specific image processing needs. In this package other three stage colours are available: blue (0, 0, 255), green (0, 255, 0) and magenta (255, 0, 255).
To install a specific workspace colour, simply extract the corresponding file archive into your gpl\tracks\chromak folder. Remember that the white workspace is installed as default, so if you want to run it, simply delete all the .mip files in the chromak track folder.
What's about chromakey?
