DESCRIPTION:
Demonstrates how to run GroIMP headless (without a GUI) and how the internal model can be automatically run several steps.
Furthermore at each step the actual scene will be rendered form two viewing directions and the result images will be saved.

The command line to run GroIMP headless is:

java -cp BASE/XL-Core/build:BASE/Utilities/build:BASE/Graph/build:BASE/Platform-Core/build -Xmx1000m -Djava.util.prefs.userRoot=USERDIR de.grogra.pf.boot.Main --project-tree --headless --debug=INFO MODEL.gsz 2> ~/render_out.txt

where you have to insert for

BASE ... the GroIMP path
USERDIR ... your root directory
MODEL ... the name of the model you want to start

HOW IT WORKS:

To run GroIMP headless you have to insert two methods. The startup()-method, which is run automatically when a GroIMP-model runs and the run(Object info)-method, which is our "new" run-method.

The run(Object info)-method mainly just calls another method where the real work will be done. In this other method we have got a loop where we derive one step and call the render-method for several times.

The renderImages()-method finally calls twice the renderer from two different viewing directions and saves each result image as exr-file.

To insert a additional cameras open the Camera panel by Panels -> Explorers -> 3D -> Cameras and add a new camera by choosing Object -> new. The new camera can be afterwards used and identified by his name.
