Re : Re: [Flightgear-devel] getting the best perfo with FG
Hi again people, problem solved ! :D I've just recompiled the latest cvs of plib, simgear and FlightGear, turned on the threads flags, and now I have a FG running up to 60 fps (i have forced the synchro with the vertical refresh).

Without any anysotropic and antialiasing, i get FG running 30 fps and sometimes 20 fps. Here are the option i use in my command line : --airport-id=LFMI --aircraft=ufo --control=mouse --enable-game-mode --enable-horizon-effect --geometry=1280x1024 --visibility=5 --bpp=32 that means i have also specular highlight and i don't have enhanced runway lighting. The FG version is the one Fred put on a webpage with the process splash screen. I had the same performances with the official 0.9.8 release. I am currently downloading the latest NVidia quadro driver for XP to check if it is the main cause. Do you have any idea, suggestion, to improve FG perfo ?

It can be done quite simply - just look at any Hurricane instrument. The ordering of the elements in the .ac file is important, or as Jim said it can be done with an animation/animation tag. Sometimes you can get away with just one material/material tag, and sometimes you will need more. In addition to instrument lighting, the Hurricane also has 'floodlighting' of the panels and some 'stray' lighting around bits of the cockpit. Not real of course, just a tad of emission as required.

[Flightgear-devel] Shadows
I have started to add some volumetric shadows in Flightgear. It uses the standard stencil method to count shadow volume (let me know if you want an implementation without stencil, it can also be done with the alpha buffer). A few days ago I thought that it would be overkill for the processor or the graphic card to add this effect, but with a few optimisations the impact on frame rate - while still noticeable - is acceptable. I can render the Concorde with a debug build so all is not lost if your computer is not 10 years old. Some screenshots here : http://sites.estvideo.net/tipunch/flightgear/lab/shadows.html Let me know what you think of that. nb: only the AC is casting shadows atm, I still need to verify how are handled other objects in the scene graph (tile objects, AI objects, etc).

Normaly a good percentage should have correct cards (or will have in the next 6 month) but I feel that some still use olders cards. 2) you think it's a good idea to enhance a bit some visual aspect of Flightgear or you think that only simulation count and all the rest is useless eye candy ;) We should have the most realism that we can collectively produce, that's what sets us apart from other sims.

Just ensure that whatever you do can be switched off or degrades gracefully (preferably). V. I think that a design philosophy that incorporates backwards compatibility is A Very Good Thing. It's harder to start with but makes things much easier and more flexible in the longer term.

Re: [Flightgear-devel] Shadows
On Friday 17 Jun 2005 20:02, Harald JOHNSEN wrote: I have started to add some volumetric shadows in Flightgear. It uses the standard stencil method to count shadow volume (let me know if you want an implementation without stencil, it can also be done with the alpha buffer). A few days ago I thought that it would be overkill for the processor or the graphic card to add this effect, but with a few optimisations the impact on frame rate - while still noticeable - is acceptable. I can render the Concorde with a debug build so all is not lost if your computer is not 10 years old. Some screenshots here : http://sites.estvideo.net/tipunch/flightgear/lab/shadows.html Let me know what you think of that. nb: only the AC is casting shadows atm, I still need to verify how are handled other objects in the scene graph (tile objects, AI objects, etc).

Re: [Flightgear-devel] Opengl rendering
Le vendredi 17 juin 2005 22:37 +0100, Lee Elliott a crit : I had to patch FG, because i need a hight speed graphic card, I don't hope any come back from NVidia. The graphics card suplyer, don't take care with the old releases, they answer to the instant mass request. With FG Beware OpenGL 2.0. There is/was definite problem with the 7xxx nVidia drivers FG. Reverting back to the 69xx drivers works ok. There is a patch to the nVidia supplied source code that will enable it to be compiled on 2.6.11 kernels. LeeE Thanks for your help, BUT Sorry we are not talking the same subject and the same target. For my usage i need an operational video card with Open GL V2.0 fully operational, with the higher speed. Only the last driver gives that performance (7664). About old drivers i did used it a long time ago without patch first (old linux release) and with patch after (new linux release), with an other old NVidia Card. (just for the fun i benchmark my old video card and the new one both with the same old driver, the benchmark gave slightly the same performance) You are talking to reduce the performance of my last video card by using that old driver only to make FG running (sorry instead of degrading the video card performance, if choose to reduce the functionalities of FG). In the future, others will have to do that choice. -- Gerard ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
Re: [Flightgear-devel] Shadows
Forgive my annoyance, but here are a few more questions. =) First of all, I am seeing a potential problem when the sun is below the horizon (during dawn and dusk) and doesn't cast any shadow onto the ground. Does your code handle this special case at the moment? If so, how? Secondly, do objects with illumination (such as the flame from the f-16's exhaust) disrupt shadows? Finally, is there a potential for this technique of generating shadow to be used on generating the effects of spot lights (eg. landing light, taxi light, logo light, etc.)?

Vivian Meazza wrote: Engines/engine/boost-pressure-psi-gauge = 46.00167 (correct order of boost) Can you try it with the CVS code? This may be interacting badly with your local changes, which makes debugging difficult. Nothing in this mechanism should require any of the new code. Also on this subject: I started integrating the RPM-based supercharger attenuation, and noticed that your code added three new engine properties: mp-pascals: Is this needed? The standard so far for manifold pressure has always been inHg. Having lots of duplicate units around complicates things; we can always do conversions in the panel animations or Nasal code. boost-pressure-psi-gauge: This looks to have been hardcoded to sea level; it should be using ambient, no? Also, must the units be PSI, or can I change them to inhg? The final name would then be boost-gauge-inhg (units go last, and pressure is implicit in the units). boost-pressure-inhg: Reading the code, this looks like an absolute manifold pressure, and not a boost at all. Is this a mistake, it looks like a synonym for mp-inhg to me.

Having lots of duplicate units around complicates things; we can always do conversions in the panel animations or Nasal code. In this case inch Hg is wrong, because it is not an SI-unit. Pascal (Pa) is a SI-Unit so that should be used in the base code. Conversion from none SI-Unit can still be done in nasal code. We should really try to use only SI-units everywhere in the base code. If this is not the case, we should start to correct that. boost-pressure-psi-gauge: This looks to have been hardcoded to sea level; it should be using ambient, no?

[Flightgear-devel] JSBSim Crash Animation Handling
I would like to present what i am developing for crash animation
handling, with JSBSim
That exemple is only a skeleton. It use Nasal, and should be tailor made
for the Aircraft.
It is only based on AC_GEAR contact points (CP) definitions, test of
values for each CP and decision or not to start the crash processing (in
the exemple we only use WOW).
Once the crash detected an animation process can be started which look
like bo105 animation (in that case everything is possible).
This is only working with FG-9.8
The last CVS modification which activate a Pause on AGL test makes it
impossible. The contact points become unusable.
Nasal exemple as attached document
