While we are at it, somebody could now add the following patch in order

This already didn't work for the FlightGear 0.9.10 release, do you have
any background information that lets you expect things to work better
_now_ ?

In my eyes you're riding a dead horse here. A much simpler approach
would be, in my eyes, to work on avoiding the use of PLIB scenegraph
dependency in FlightGear wherever possible and to simply copy the
remaining PLIB dependencies - mostly joystick, networking and GUI -
into SimGear. The few patches that make their way into 'official' PLIB
could easily be incorporated into our copy as well.

Cheers,
Martin.

Perhaps you've been building against old OSG headers. Few weeks ago
Robert Osfield has removed a header file that contained declarations
for the osgViewer component and added a new one - fortunately Fred
Bouvier took on this and added the appropriate fix to FlightGear today,

 Thanks, but the problem is in OSG.  I have been building and installing
 debian packages.  Its not the supported way to build, so when it quit

Ah, ok. Simply compile OSG from source and install just by make

[Flightgear-devel] OpenSceneGraph 2.0

2007-06-15 Thread Jonathan Wagner

Just a thought for the rest of the list.  Now that OpenSceneGraph-2.0 
has been released, what are the thoughts on setting that as a fixed 
dependency for now (i.e., future development should work on 
OpenSceneGraph-2.0).  With one of the latest patches to the plib branch 
in CVS, FlightGear still compiles with plib-1.8.4 which is included in 
many Linux distributions.  I have a feeling that OSG 2 will soon be the 
version of OSG available in many Linux distributions.  Having OSG 
support just _work_ would allow developers to focus on FlightGear 
without also having to keep up with the latest daily developments in OSG.

Just a thought,
Jonathan Wagner

I think this is an excellent suggestions, and to do otherwise will be to
invite a *lot* of support headaches on ourselves when we finally do a
release based on OSG.  If the average user has OSG-2.0 (or the most recent
release at the time) and we depend on features in CVS, we will make it very
difficult for non-developers to get flightgear up and running on their
systems.

Our approach with plib is that if we absolutely must depend on something in
cvs, we push the plib folks hard to get that into an official release first,
then we cut over and allow our code to depend on it.  This is not without
headaches, but it's worked pretty well for us in the past.

Curt.

[Flightgear-devel] OpenSceneGraph, feedback - on Fedora Core 6

2006-11-09 Thread Matthias Boerner

Hi,

I got everything compiled and did a short performance test compared 
between the CVS-Version of FlightGear with PLIB of 26th, October and 
yesterdays OSG release:

With the options 

--timeofday=noon --prop:/sim/rendering/fps-display=true --bpp=32

both versions show almost the same rate of fps with a small advantage to OSG 
about 1 to 10 percent.

If I increase screen size to 1280x1024

--timeofday=noon --prop:/sim/rendering/fps-display=true --bpp=32 
--geometry=1280x1024

OSG shows about 5 to 20 percent higher fps then the PLIB version.

My frame rates are between 80 and 100 fps (Athlon64 4000+, GeForce 6600 GT 
and 2GB Memory).

 Hi Olaf,

 I have used your project files / precompiled libs to compile fg with osg

 A file simgear_config.h is missing; there is a simgear_config.h.vc5, 
 after renaiming to *.h it works.
 2 files had to be added to the simgear project file: 
 SGStateAttributeVisitor.cxx and SGTextureStateAttributeVisitor.cxx
 and 1 file has to be removed from the flightgerlib project file: 
 rotorblade.cpp to get compatible with actual cvs.
   

Yep, I have to post an update.
 A very big thank you to Olaf Flebbe, with your package it's very easy to 
 compile fg from the scratch with mcsvc express.

   
Thanks!
 But there is one problem with the running flightgear than: it's about a 
 factor 2 slower than the flightgear with plib (and shadows on)!
 I don't know if this can be improved with other compiler flags, but I am 
 a little bit surprised.

 And I fear, that with shadows the frame rate will be decreased further.

 I am using a P4 2.2Ghz with GeForce  Fx 5600Go

 @Olaf:
 what is your experience regarding the frame rate with osg vs. plib?
   
I do see a dramatic slowdown, too. A GeForce FX 5200Go and an ATI 
X1600Pro both show a significant slowdown. I have to doublecheck 
compiler settings The Slowdown on the ATI Thingy is definetly not 
CPU bound...

Hi Mathias:

1. Further investigations, new insights regarding the FG-OSG black
screen problem
- must be a terrain/ground problem, the a/c  is located under the
surface when one selects special airports.
- found it out by using the UFO, it is located under the surface but if
you go up to the ground-surface then you can see the normal 3D-scenery.
As you can't go up with the normal Cessna you get this black screen
because you stuck in the earth.
- there are also missing ground tiles (white area, located between EDDF
and Feldberg, see screenshot) and mismatching ground-tile boarders (see
second screenshot, London scenery)
2. Therefore I forget about accusing the sceneries at the moment, all
sceneries are displayed (nearly) the right way when the UFO is used and
flies to the ground-surface
3. Just to complete all, one other little problem: 3D-billboard objects
are not displayed right now (ie trees)
4. Hope this helps you a little with debugging

The new screenshots:

 important message/information for you as we user don't know how far the
 implementation process has grown until now and what is still lacking.
 In general I was very surprised how far you have got in this short time
 and that much more is working as I expected before.
Thanks.

 It was only a short test yesterday evening and so was today due to
 lacking sparetime.  But I found out that the EDLA  scenery is only one
 exampe of a lot of sceneries behaving the same. Not only
 3D-objects-heavy ones like the Paris or London one but also the Hamburg
 scenery which has got only an overviewable number of 3D objects.
 But if you write that the ac3d loader has to be improved now then I
 think we should wait with further investigations about these sceneries
 until this task has been completed.

  May be you can put that on any ftp/whatever server before sending a mail
  bomb :) ?

 No problem at all, next weekend could be a good time to do so.
Well I will leave at Thursday evening until Sunday. So this week has mostly 
passed for osg and flightgear :-/ ...

 First I thought of the normal and uncritical display artifacts. But
 the dark screenshot only to demonstrate that the GUI displays fine.
 Here they are:

 http://home.arcor.de/vollnhals-bremen/OSGErr/fgfs-screen-0154.jpg
Ok, for the black screen I am at the moment a bit clueless.

The transparency stuff is due to a switched off z test. I believe that the old 
plib version did so too.
I know that problem. I am working on integrating the panel into the 
scenegraph. That will be beneficial anyway.

Re: [Flightgear-devel] OpenScenegraph MSVC8

2006-10-31 Thread Maik Justus

Hi Olaf,

I have used your project files / precompiled libs to compile fg with osg 
from the scratch. It worked with only negligible problems.
A file simgear_config.h is missing; there is a simgear_config.h.vc5, 
after renaiming to *.h it works.
2 files had to be added to the simgear project file: 
SGStateAttributeVisitor.cxx and SGTextureStateAttributeVisitor.cxx
and 1 file has to be removed from the flightgerlib project file: 
rotorblade.cpp to get compatible with actual cvs.

A very big thank you to Olaf Flebbe, with your package it's very easy to 
compile fg from the scratch with mcsvc express.

But there is one problem with the running flightgear than: it's about a 
factor 2 slower than the flightgear with plib (and shadows on)!
I don't know if this can be improved with other compiler flags, but I am 
a little bit surprised.

And I fear, that with shadows the frame rate will be decreased further.

I am using a P4 2.2Ghz with GeForce  Fx 5600Go

@Olaf:
what is your experience regarding the frame rate with osg vs. plib?

Maik

2.) Is the stuff in SimGear/simgear/scene/util/ still needed ?

Hmmm, maybe its CPPFLAGS=-I/opt/OSG/include ./configure (it's been a while and I'm going from memory here.)There once was a way to add to EXTRA_DIRS from the command line, but that apparently was lost along the way at some point.

[Flightgear-devel] OpenSceneGraph

Hi,

It took some time. And still not everything ready. But here the promised
checkin preparations.

As a first thing, you will need an updated OpenSceneGraph version that
containe 3 additional patches.
1. most important an updated ac3d loader - that is our most used one ...
2. a fix to the RGB Loader
3. a small backport of OpenSceneGraph-CVS doing the right OpenGL version
checks ...

You can find that tarball at

ftp://ftp.uni-duisburg.de/FlightGear/Misc_maf/OpenSceneGraph-20061029/OSG_OP_OT-1.2-Flightgear.tar.gz

I am working on getting the two patches upstream ...

For the Flightgear part, I will past that sent mail create the

PRE_OSG_PLIB_20061029

branch.
Whoever needs that plib stuff can still live on that branch.
Caution, I for myself have no plans on merging ongoing work on that branch
back to HEAD. So please do not do huge development work on that.

I have in the past week worked on hunting bugs and display problems.
So I hope that I have an at least usable checking.
The MSVC Project files are not yet updated.

I will tell when I have checked in :)

Greetings

Mathias

[Flightgear-devel] OpenSceneGraph


... is now in.

There are plenty if places where something is marked with an OSGFIXME
comment. At least these places need to be fixed at some time.

For everybody willing to help:
feel free to provide patches/fixes/improvements/cleanups.

I think that we should make use in the longer term of the Producers 
capabilities for multiple view installations.
But not only multipipe installs will benefit from that. The Producer will also 
help to get benefit from multicore SMP machines.
For that the following article is of huge interrest:
http://www.donburns.net/OSG/Articles/OSGMP/

Having read that, there is a guideline for writing code for use with that:
Do *not* modify the scenegraph from outside an update callback of any 
scenegraph element.
Also do not read any application data in the cull or draw stage. Cull or draw 
callbacks can be installed but they should not read anything from the rest of 
the application except the scenegraph and they should not modify the 
scenegraph structure.

happy hacking!

Greetings

 Mathias

We should branch the data and maybe the doc repositories. At some point, the
improvement brought by OSG will show up in data files too.

Hi Mathias,

I tried compiling your OSG tarball on cygwin, but hit an error:

c++  -O2 -DWIN32 -DNOMINMAX -W -Wall -mnop-fun-dllimport
-I../../../../include -
I/usr/local/OpenThreads/include -I/usr/local/Producer/include  -c
../ESRIShape.c
pp
../ESRIShape.cpp: In function `bool readVal(int, T, ESRIShape::ByteOrder)

   [with T = Double]':
../ESRIShape.cpp:69:   instantiated from here
../ESRIShape.cpp:38: error: `::read' undeclared (first use here)
make[4]: *** [ESRIShape.o] Error 1

The error seems quite reasonable. ESRIShape.h provides various prototypes
for read(int), but none with multiple arguments as is being called at that
point.

Anyone know what might be going on? Anyone else hitting the same issue, or
is there an IF_DEF that's messing with my install?

Try either including
#include unistd.h
(is this available on cygwin??)
or alternatively you can skip that plugin by removing ESRIShape from the 
PLUGIN_DIRS variable defined in OpenSceneGraph/Make/makedirdefs.
We do not need that plugin for flightgear.

 He is already working on that so that at the time we check that in we have 
 something that works about as good the Linux port.
 I have an IRIX machine available. Erik may hopefully excuse me - I would try 
 to recompile that on IRIX past it has appered in CVS.

Building OSG on IRIX is really simple, just follow the rules, the same
for Solaris. Yesterday I tried compiling from CVS on both platforms.
FreeBSD will follow right now,

OSG CVS compiles and works great on FreeBSD-5.3 with Radeon9200 and
XOrg driver - at least those examples that don't require GLSL.
The burning Cessna is a _very_ impressive demo !

 Hmm, last time I looked OSG wasn't ported to Cygwin. Is it now, or do we
 have a potential problem here?

 I built OSG under MSVC 8 some time ago now. Wasn't easy, but got there in
 the end.
   
I will provide a  3rdparty package Binary ZIP archive, like the one on 
http://www.oflebbe.de/oflebbe/FlightGear even for the patched OSG needed.

Since I had massive problems with the static OSG I provide a fully Dll 
Build rather than a static build this time. As a positive side effect it 
reduces link time dramatically.

2006-10-26 Thread Vassilii Khachaturov

Great news! Thank you very much for the porting.

 The rain stuff as well as the render surface stuff is nothing too complicated 
 and already available in osg, but that needs to be done and tested.
[SNIP]
 The 3d clouds are something to think about. osg can assist here but I need to 
 think about that.

I'll be happy to try to help to port/switch these. Of the above, I don't 
  quite find my way around the 3d clouds code, so I'll be starting with 
the rain/lightnings when the check-in is done; meanwhile I'll read about 
the OSG - never been into anything except overviews there. BTW, current 
rain (as opposed to lightning) is not branching the scene graph via 
plib, but rather directly drawing stuff through GL primitives; I 
wouldn't be surprise it it works as is (with the same ugly artifacts...) 
I'll try to properly port it to OSG. I'm especially happy about the OSG 
transition as I have some multitexturing-based rain prototype in the 
works, and I was unhappy about further direct GL ugly hacking needed 
because of that, as plib has no m/t support. AFAIU, OSG does have it, so 
it's really great news.

Since for the porting I'll have to use both branches, I'll be using both 
of them wherever you put the OSG stuff. Personally, I agree that the 
HEAD is the way to go.

Vassilii

Hi,

 I am eager to see it in CVS. It seems natural that the flow of innovation
 goes to HEAD and branches are used for freezing functionalities and doing
 maintenance release. Many big projects are doing like that, gcc for
 instance.

 It should be easier to do that because doing branch merging can be risky at
 a large scale. It is better not to rely on it and accept the idea of doing
 things twice if a bug appears in a branch and the trunk.

 So, IMO, we should create a pre-1.0 branch now, fix the more embarrassing
 bugs ( and missing features ) in that branch and let the innovation go in
 HEAD.
Ok.

 I hope Curt is not thinking about duplicating the repository like it was
 done for version 0.8.0 :-)

 BTW: I presume only SSG has been replaced and PUI/PUAUX/JS are still
 needed. right ?
Yep. I believe that we should import them into SimGear...

Re: [Flightgear-devel] OpenSceneGraph


Ok.

In summary I will create a branch this weekend in SimGears and FlightGears 
CVS.
That branch will contain the old plib based code. Whoever needs to work on 
that/stick with that - not recommended plib/ssg is deprecated now - can live 
on that branch.

Past that branch I will push into CVS what I have now.

Help is welcome then.
May be I can coordinate what needs to be done and what is already in the 
works ...

 The current 3D clouds don't work on every machine, and I think its

 better tested than the one we have in FlightGear.
There is no direct 3D Cloud set on osg.
But we have an impostor implementation that renders into a texture. That osg 
builtin RenderTexure replacement is more flexible and knows a primary and 
secondary target. I plan to use FBO's as primary target - that should be the 
best choice with todays graphics cards anyway - and as a fallback something 
that is allways there. Maybe we can make that configurable.

But yes. I strongly believe that we are much more portable and much more 
people will see 3d clouds. Or better everything that requires rendering in a 
texture ...
