I've just flown over Chalgrove (near RAF Benson) at night. Except I didn't know it was Chalgrove I then spent 2 hours trying to work out what this huge 3 runway centre-intersecting airport with full runway lighting and PAPIs was. ;-P Its obviosly very mis-laid in FlightGear (maybe by DAFIF)as Chalgrove in real life appears as a classic RAF undeveloped 3-axis triangular airfield with very minimal infrastructure.

If GPUs were better CPUs than CPUs, guess what we'd all be running for our performance-critical operations? Specifically, find me an implementation of string search (the fundamental operation in gene sequencing) that works on a GPU. Or index building (database stuff); or a big if()-tree based on complicated state (server-side business apps)... GPUs have dedicated hardware for the purpose of 3D rendering. Most importantly this includes: + Parallel, pipelined, single-precision 4D vector operations. A typical CPU has 2 or 3 floating point pipelines. A high end GPU can have dozens. + 1- 2- and 3D lookup tables (i.e. textures), with built-in interpolation/extrapolation (i.e. mipmapping & filtering). The memory bandwidth they can bring to bear on this stuff just crushes what a CPU can do. It also includes less generically useful stuff, like perspective-correct interpolation of vertex constants across a polygon. And it lacks a lot of stuff that CPU users take for granted: + High clock speeds. A CPU can dispatch single instructions 10x faster than the fastest GPU. This means that anything requiring quick decision making or iteration belong on the CPU. + Registers and cache. CPUs get special bonuses for iterating on the same data they were just using. GPUs get almost nothing (there's a little bit of caching that goes on within a single polygon's texture mapping, and a vertex cache of recently transformed vertices), and have to fetch it from main memory every single time it's used. + Turing completeness. Other than recent NVidia hardware, GPUs simply can't decide a lot of problems without CPU intervention anyway. + Double precision floating point math. Sometimes, single just ain't enough. And lots of others. Basically, this is all just a long winded way of saying "use the right tool for the job".

Why not? It makes sense. As a classmate of mine pointed out: the GPU is just a chip for matrix manipulations. ..aye. I'm just wondering how much work we can yank off the Control Process Unit and dump onto these General Purpose processing Unit_s_. ;-) I was referring to Graphics processing units. ..me 2. ;-) Am I missing something here? :-\ A joke ;-) (see the ";-)" smiley of Arnt) ..well, all good jokes can't come up with a potential like the http://gpgpu.org; your average recent GPU chews code 6 times faster than your average CPU. So, we can use part of the GPU to show pretty pictures, and the remainder, say "half", to say, triple FG framerates? ;-) Are there any decent books about those Navier-Stokes equations and how ..chk these: http://download.nvidia.com/developer/SDK/Individual_Samples/DEMOS\OpenGL\src\gpgpu_fluid\docs\GPU_Gems_Fluids_Chapter.pdf (Yeah, those back-slashes worked in Konqueror!!! 8o)) http://www.gpgpu.org/cgi-bin/blosxom.cgi/Miscellaneous/Books/ http://www.gpgpu.org/cgi-bin/blosxom.cgi/Miscellaneous/Courses/ http://www.gpgpu.org/cgi-bin/blosxom.cgi/Miscellaneous/ http://download.nvidia.com/developer/SDK/Individual_Samples/samples.html#gpgpu_fluid http://www.strangebunny.com/techdemo_stokes.php (arrrgh bummer, should have been done in OpenGL) http://www.eet.com/in_focus/silicon_engineering/showArticle.jhtml?articleID=55300900 http://www.eet.com/showArticle.jhtml?articleID=55300904 ..and you might wanna compare Microsofts take with the other guys: http://www.cs.unc.edu/Events/Conferences/GP2/program.shtml ;-) Thanks for the links! I'll look deeper into them after the exams. to implement them in C or java? ..nonono, FG is C++ and will likely remain so for all sortsa good reasons I was buried under when I asked "Why not C like in the kernel?", an extensive discussion of the wisdom of writing Java code can be found over at http://Groklaw.net/, hints on "follow the money", also points towards Redmond and Lindon, Utah. I knew that FG was written in C++ :-p. Problem is that I haven't been properly educated to program in C++ (yet).

Maybe the center of gravity > needs to change a bit? Two things: I have the impression that two notches of flaps are set per default on startup, it might me worthwile to remove this. And there's a second point which becomes visible when you use the HUD: http://document.ihg.uni-duisburg.de/bitmap/FGFS/PC7_02.jpg The third 'scale' from the left has two markers (the first is power, the second is airspeed and the one I meen is the one that comes next). The marker on the right side displays the elevator position and the one on the left side !? I don't know why this isn't centered and I, don't know how to make it centered. Actually I don't know even know what it means, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -- ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
