ARINC661, for example, has a clear separation between the display graphics and the rendering engine. The ARINC661 instruments are based on SVG vector-based artwork, compiled into byte code (purely for size issues). The display units 'run' this byte code and convert it into the appropriate image. Problem with OpenGC: The display graphics are hard-coded in the source code of the project, and currently only Boeing-related. No Airbus, no Honeywell, and definitely no steam gauges. For example as comparison, FS2004, as well as the FG instrument system, use stacked bitmap images which have arrangements defined in an XML file. Why not make an application that does that externally? In the long run, if OpenGL is used as a rendering API, it could also be used to render vector-based images as well. I'm targeting a generic audience, from a Cessna flyer to a 744 or 787 pilot. Keep the actual graphics out of the program code, but the rendering in there. For speed, you could reduce this to a VM-based architecture, with the instruction set corresponding to OpenGL rendering commands and the data in memory being the A/C data pulled out of a simulator like FG, FS2004 or PS1, hence almost a full ARINC661 implementation. On the hardware front, each DU could be driven by their own TFT display (portrait) and a Mini-ITX form factor board on the back. MiniITX boards have LVDS connections on board, and are powerful enough to run 2D graphics. If a DU fails, the network code could be programmed to detect that and let another DU take over. Some of the intelligence could be transferred from FG to the external applications and interface logic, while still keeping FG up to date on any changes, through the property system. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
