Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Simulador 747 a escala real
The projectors are (3) short throw 1200x800 native resolution units, mounted on the ceiling. Each projector is first mechanically aligned using the projector test pattern. Next a warping mesh based on projector location and screen dimensions is created and a test pattern using the mesh is produced by FlightGear. The warping mesh is then adjusted to tune the resultant image thrown on the screen as well as mechanical adjustments. And as a final step the "production" image is adjusted by setting the viewing heading for the side projectors for horizontal alignment and projector internals and mesh recalculations for the vertical as required.
Los proyectores (3) unidades de corto alcance con 1200x800 de resolución nativa, montado montados en el techo. Cada proyector primero mecánicamente alineados con el modelo de prueba del proyector. A continuación una malla de deformación según la ubicación del proyector y dimensiones de la pantalla y se crea un patrón de prueba utilizando la malla es producido por FlightGear. La malla de deformación se ajusta para ajustar la imagen resultante tirado en la pantalla, así como los ajustes mecánicos. Y como paso final de la "producción" de la imagen se ajusta mediante el establecimiento de la visión en dirección al lado de los proyectores para la alineación horizontal y los componentes internos del proyector y nuevos cálculos de malla para la vertical como sea necesario.
The image warping software is contained in the CameraGroup.cxx based on the [[OSG]] code for a spherical panoramic display. Tim Moore adapted the source to run with the FlightGear camera group and I extended it to display a warping mesh for a cylindrical panoramic display. There is a stand alone utility to create a mesh warping file that can be tailored for each projector and is loaded at FG init time.
