'''Headless mode''' is still something that could be improved; currently it seems limited to <code>--disable-gui</code> which is more about disabling user | |||
input (message boxes etc) that may block unattended activities. SimGear | |||
can be configured to be built in headless mode which probably isn't what | |||
you want. | |||
Currently there are parts of FG that require the scenery to be loaded | |||
(for the ground elevation) - the easiest fix for this is probably to | |||
either not have any scenery or to default to a position in the ocean (we | |||
always used to use lat -25, lon-25) and/or use a small window.<ref>https://sourceforge.net/p/flightgear/mailman/message/37344888/</<ref> | |||
A set of different headless modes was always in Edward's TODO list for the | |||
test suite infrastructure, however he ran out of time for now. | |||
Anyoneelse can add it though. Edward's idea was to build it up in steps, having | |||
unit as well as system/functional tests for each. Firstly running the | |||
fg main loop in the absence of a scene graph and with a minimal set of | |||
subsystems present, then with a basic scene graph (no scenery, testing | |||
with basic geometric objects, and a basic 'sphere world'), and then | |||
rendering frames to bitmaps on disk or in memory for per-pixel checks. | |||
Scenery loading would be absent from all these basic tests, simply due | |||
to not having access to it - the test suite would require very basic | |||
and tiny test-suite specific scenery tiles for efficient testing. | |||
Edward would recommend following such a route if more advanced 'headless' | |||
modes are desired, as that would help with long-term stability of | |||
these modes, and bring in a major piece of infrastructure into the | |||
test suite that the project could really benefit from!<ref>https://sourceforge.net/p/flightgear/mailman/message/37345003/</ref> | |||
