Re: [osg-users] [vpb] .tif and .tfw

[Pierre Bourdin (gmail)]

Hi Lucie,
to cut your terrain you can use a lot of tools...google is your friend,
you'll find a lot of info on that topic.

If you have the budget for it, one of the most convenient tool is
probably GlobalMapper: http://www.globalmapper.com/

Of course gdal_translate can do it too:
http://www.gdal.org/gdal_translate.html

I believe 3Dem can do it:
http://freegeographytools.com/2007/dem-terrain-depiction-using-3dem

and probably QGis: http://www.qgis.org/ 

Hope it helps.
Pierre.

Re: [osg-users] [vpb] .tif and .tfw

[Pierre Bourdin (gmail)]

Hello Lucie,

When looking at your log I see that the tiff texture is reprojected...

started DataSet::createDestination(3)
reprojecting to file temporaryfile_013c07_0100_deme.tif
reprojecting to file
temporaryfile_S4_06032_5215_20061018_m20_1_utm20.tif
Time for after_reproject 8.389910

as recommended by Shayne, you should re-project your data, first it will
save you some processing time and secondly it will allow you to detect
projection problems more easily...


To avoid aliasing artifacts when accessing data, you can also use
gdaladdo to store the mip maps in the .tiff, like explained here :
http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/osgdem
(but it won't fix your projection trouble)

Otherwise I believe there was some problems with GDAL 1.5 at least with
some release ;  particularly the 1.5.0 was buggy...

If using known to work data, you still got strange result, try to update
gdal lib...

I've downloaded and tested on my machine (Debian 64bits - osg 2.9.7)
your Boston terrain and it looks normal... but the files are probably
not reprojected...

You could also try to look at your data in a GIS tool like Quantum GIS
http://www.qgis.org/

Just to see if everything is looking good ?


Pierre.

Re: [osg-users] [vpb] .tif and .tfw

[Pierre Bourdin (gmail)]

Hi Lucie,
maybe you could try to use the "OSG_NOTIFY_LEVEL=INFO" flag to know a
little bit more about your problem...

What are the version of osg, vpb and gdal you are using ?

Also you could maybe try to use some known to work data like the Boston
sample of the OsgGis project ?
http://osggis.org/downloads/boston-sample.zip

Cheers, Pierre.

Re: [osg-users] Quad buffered stereo?

[Pierre Bourdin (gmail)]

Hi,
is there any limitation when using last Qt version (4.6) and Quad buffer
stereo ?

I'm using Qt 4.3 and OSG 2.8.2 in an application and in the tests I had
made for upgrading to newer version of Qt the Quad buffer stereo was not
working anymore...
I was missing time so I didn't look further and and kept Qt 4.3...

Pierre.

Re: [osg-users] [ANN] The book OpenSceneGraph Design and Implementation is published

[Pierre Bourdin (gmail)]

Dear Wang,

I just wanted to add a small question off the mailing-list.

I've seen in the mail, you have been collaborating with many Chinese
Universities among which some people of the Beijing Forestry
University...

I am just starting a project about Virtual Landscape Visualization with
Xavier Pueyo from the University of Girona (SPAIN) and Marc Jaeger from
the CIRAD (France), and other partners...

I know Marc Jaeger is working with a lot with Chinese Partners, since he
was one of the joint Director of the LIAMA (Sino/French Laboratory for
Computer Sciences: http://liama.ia.ac.cn/wiki/)

Could you be interested in collaborating with us on an international
project on the topic of Landscape Visualisation ?
  
Nothing is started yet, but we are already looking for partners.

Regards, Pierre.

Re: [osg-users] problem with quadro cards & database pager / terrapage terrains = black tiles

[Pierre Bourdin (gmail)]

Hi Vins,
I am running Delta3D terrain simulation & VPB built terrain on some
quadro card on Linux 64-bit system without any trouble...

But it might be different, as I've not such big database as you are
talking about and the terrain is not a terrapage file.

Does the problem only occur on very large database ?

What is your standard card vs Quadro card ? 
What is your driver version ? 
what is your system ?

If it is not a driver related problem, it might be a problem with some
VBO/PBO functions...

Pierre.

Maybe you could have look at delta3d Compass class:

I think it is doing exactly what you're looking for...

If you want to know which low level operation fail using vpbmaster you
could maybe try using "strace"...
strace -v -o /tmp/vpbmaster.log vpbmaster
Take care the log can rapidly increase, but it should give you a
complete report about all operations done.

Re: [osg-users] osgviewerQtWidget Quadbuffer Stereo & Alpha Problems

[Pierre Bourdin (gmail)]

Hi Scott,
does it works with osgviewer ?

something like 

osgviewer --stereo QUAD_BUFFER cow.osg

should display the cow in stereo without any error...

Also I can't remember it exactly, but I think you have to re-init the
context or something like this when switching to quadbuffer stereo...
When switching in other stereo mode it is not necessary...

Maybe others can be more helpful...

Pierre.

Can you share a little bit more about the QuickTime Plugin ?
Do you have some recommendation for using it ?

What is the *best* codec to use ? 
Does it work well with mpg format (mpgv for vidéo, mpga  for audio) ?

On which plate-form are you using it ? 
I think it is not available on Linux ?

Thanks,

- try using osgviewer with any 3d model, like osgviewer cow.osg 

- try the examples applications if you choose to build it in the cmake
config process.
They should be in share\openscenegraph\bin

Anyone else has had trouble with osgmovie ?

I'll try with OpenSceneGraph-2.9.5 to see if ffmpeg handles it
correctly.

[osg-users] Proximity trigger ?

[Pierre Bourdin (gmail)]

Hi all,

is there something that looks like a proximity trigger in
OpenSceneGraph ?

I mean, something that can start an action when the user (the camera)
goes close or in contact with some particular object ?

I know it exists in Delta3D but I don't remember having seen it in
OSG...

Regards, 

Pierre.

Did you look at the osgstereoimage examples ?

Most of the code related to stereo is in the DisplaySettings class, but
there is code related to stereo also in the SceneView class
(computeLeftEyeViewImplementation,
computeRightEyeProjectionImplementation etc...)
and the graphic context is setup in View::setUpViewAcrossAllScreens.

If you don't find what you're looking for, try reformulating your
question...


Robert should be back next week, maybe he can give you the solution...

Hope it helps, 

Pierre.

Could be that the binary version plugin is not made for 3DS Max 2010...

You could try to rebuild it from source may be ?

you can maybe have a look at the osggis project

It does this quite well.

I've used it for tracing the river aver the terrain for example...

[osg-users] Best video format for a fullscreen video rendering ?

[Pierre Bourdin (gmail)]

Hia all,
I want to show small video with sound and if possible subtitles in an
OSG application.
I guess the best way is now to use ffmpeg plugin like in osgmovie... 

I think, for the sound it needs some external tool like SDL to play the
audio part.

Have you got any feedback about the compression format to use ?

Is there somebody working on integration of Qt Phonon in
OpenSceneGraph ?


Thanks, Pierre.

Well I've only made half of the work, putting the 4600 on my machine...
(I didn't test the 3450 in the other machine).

The bad news is that the bug is still there. I've upgraded the drivers
to 185.18.14 (last one) just in case it could change something, but alas
nothing's better.

Hi Kim, J-S,

I've run the osgOcean_debug and got the dump.
http://perso.imerir.com/bourdin/wiki/doku.php/en/projets/osgocean#osgocean-1.0-debug

I've made an archive including a screenshot the tiles that were created
and the debug file.

I've made 2 runs, one with libfftss & libfftw3f but it does not change
anything about the problem...

Ah, and I've made some tests on another machine, with a diiferent
Graphic card (Quadro 4600): the waves are working well, but I've a
trouble when diving underwater... When I reach the water surface, the
view is flickering until I'm completely underwater... Has someone else
experience the same effect ?

Hoping it will be helpful.

Re: [osg-users] [3rdparty] Is the osgOcean Linux bug still present?

[Pierre Bourdin (gmail)]

Hi Kim,
I'm sorry to tell it is the same for me...

I've compiled osgocean from svn trunk and tag 1.0 with
fftss-3.0-20071031.tar.gz 
linked with OpenSceneGraph Library 2.9.4

I've just made a simple run/shutdown log:
http://perso.imerir.com/bourdin/wiki/doku.php/en/projets/osgocean

If you need more informations, tell me how I could help.

Cheers, 

Pierre.

Hi Kim,

first congratulations for this new osgOcean 1.0. It's really nice.

The fix for the shader bug on 7 series nVidia cards which caused an
error when indexing arrays using uniform variables is working well for
me. I can see osgOcean demo on my computer now.

I'm not sure about what you call the "patchy ocean surface bug", but now
that I can see osgOcean demo on my computer, it doesn't looks like the
previous one... The waves look more like squares, so it's probably this
bug ?
I've made some snapshots:
http://perso.imerir.com/bourdin/wiki/doku.php/en/projets/osgocean

I've also a problem when resizing the window (snap 5) 

This is probably related to Kwin and Kde window manager...

Hi Chris,
you could be interested by the work of Kevin Boulanger
http://www.kevinboulanger.net/grass.html

For a parallax sample using GLSL there are probably a lot of samples on
ATI or Nvidia developper site, but maybe you'll find some interesting

I was happy to have the stereo with my notebook, even if it is eating
all the battery, heating the office... It's working ;-)

But yes the drivers is crappy, and they have stopped updating it if I've
well seen...

If the stereo is working on OSX, it might be an interesting
alternative...

Re: [osg-users] Stereo Problem

[Pierre Bourdin (gmail)]

Quad stereo is working well on my thinkpad T42p with a FireGL.

I've used it with Openscenegraph may times and it works well.

It is very convenient to make a nice demo with a 3D DepthQ projector...

It just miss a modern shader support...

If you want to use it for active stereo, you need an adapter to
synchronize the IR emitter...

I now some notebook have quadro card too, so I guess it is also working.

Re: [osg-users] FirstPersonManipulator

[Pierre Bourdin (gmail)]

I've just made an osgViewer with a FirstPersonManipulator...

I've tested with a terrain...

The Manipulator is shouting: "you are lost in space!"

What kind of model you suggest to use it ?

I had no time for a more complete test, so maybe I missed something
obvious ?...?

At least I can say it compiles on Linux Debian Testing with 2.8.1-rc5
without any problem...

Hi Robert,
I just finished compilation on Debian testing, without any trouble...

Everything seems to work perfectly.

I'll do some more tests this afternoon...

Yep ,but the terrain is built and rendering is slow and popping but
correct...

I'll tell you more precisely at the end of the afternoon, cause I can't
get the machine for now...

But the graphic board is an integrated ATI Radeon Xpress 1150...

The drivers are probably from before September 08...

Sorry, I couldn't find another machine for a quick compatibility test

Re: [osg-users] Help: Using OSG To Build Tiled Display Wall

[Pierre Bourdin (gmail)]

Hi,
an interesting approach for a distributed rendering system is FlowVR...
http://flowvr.sourceforge.net/


I know openscenegraph has been used with Delta3D team with CIGI Image
Generator: http://cigi.sourceforge.net/ 
To not only advertise for concurrent project ;-)

Re: [osg-users] VPB stuff

[Pierre Bourdin (gmail)]

Hi,
I can confirm it works well with many textures...

Here's screenshot of some terrain build with 2 textures:
http://perso.imerir.com/bourdin/wiki/doku.php/en/projet/massane


The only problem I have is with Shapefile, but I'm using osggis for
that... If you know how to use them with osgdem ? I'm interested...

For the --terrain option, it works also very well, but I have to disable
GL_ARB extension with my ATI otherwise it crashes.

Re: [osg-users] Remote execution and OSG

Hi all,

maybe the first thing to do is test with some easy application, like
xclock or something else to be sure your X forwarding is working...

I've just tested yesterday, with "ssh -X" and it was working for me...
But it's extremely low...

I completely agree.
Congratulations, It's really nice !

Without any intention to influence you in any way, having such nice
rivers would be really wonderful ;-)

Re: [osg-users] terrain database popping...

[Pierre Bourdin (gmail)]

Hi all,
what could be interesting to would be the integration of automatic
vegetation placement like the work done in Delta3D:
http://www.movesinstitute.org/~wdwells/4181/index.html
I'll be glad if can give any help on that part...

So far I've never succeed in adding a vector layer mapped to an
osgTerrain using osgdem (I can open each separately but not combine
both).

But it was done easily with osggis...
I have juste started to look at it and it looks also impressive...

Re: [osg-users] Converting .ive model to .osg - including textures

Hi J-S,

you can query the options via:

osgconv --format osg

It's verbose, but very useful...

Re: [osg-users] [build] Windows binary download

[Pierre Bourdin (gmail)]

Hi Mattias,
I've just checked this morning this file:
http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8/binaries/Windows/VisualStudio9/openscenegraph-all-2.8.0-win32-x86-vc90sp1-Debug.tar.gz
Using tar on my Linux Debian gave me some errors...

I've just tried again and have not any error now !
Everything's fine.

Thanks for all the work you've done, Pierre.

Re: [osg-users] [build] Windows binary download

[Pierre Bourdin (gmail)]

HI all,
I agree with all of you, it is probably more convenient to have ZIP
files, but the one that is not able to open a TAR.GZ archive will
probably not be able to use Openscenegraph...

I just wanted to point out, about those binaries for windows, that some
of the TAR.GZ are corrupted... at least the x86-vc90sp1-Debug
It is not a big issue since user can just pick up individual packages
instead of the "All_Debug" package...
But it's better to fix it.

I've just tried the MSVC09 download at
http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8/binaries/Windows/VisualStudio9/

Re: [osg-users] Converting large obj file with osgconv

[Pierre Bourdin (gmail)]

Hi,

thanks for your help we've done the conversion with one file (not the
biggest), but now when I try loading the data in IVE it makes a
segfault ?!

I've also successfully converted the IVE to osg, but it make the same
segfault...

I'm using OpenSceneGraph Library 2.6.1 with openthreads-version-number
2.3.0

Below is the log in the console setting OSG_NOTIFY_LEVEL=DEBUG.

Maybe blocking the optimisations as suggested by Marcin Prus could
help ?

If you have any idea, for the conversion or for viewing the object ?

We just would like to view the full object in a "low" resolution, and
zoom to some part of the object in full resolution...
It seems to me that building an LOD hierarchy, would be best way to do
it... But is it the best in our case (we have a single big cylindrical
object) to use "simple LOD" or do we need to build a pagedLOD or
something different ?

Any advice is welcome, Pierre.

Re: [osg-users] Compilation of OSG with /MT option.

Hi,
just to confirm that adding the DebugCRT DLL with the DLL of OSG it is
possible to debug a project using the libs...

The test I've done was using the Openscenegraph compiled with MSVC09_US
in a project compiled and debugged with MSVC09_FR:
Without the DLL you can compile but windows refused to execute the
project.
With the DLL you can compile and execute/debug the project.

Thanks , Pierre.

I'm doing just like you (only US/English), but the students are
complaining and MSVC has been installed in FR/French as there is a
french version.
That's also why I didn't detected the problem in advance...

I'll do some tests to see if I can debug a project...

Using this, I mean releasing the project with the "Debug_NonRedist dll",
can I work on my project (compile/execute/debug) on the new machine ?
I'm not sure you can understand what I want to say ? So let me be more
precise...
I had trouble doing some work with OpenSceneGraph with some students
because the installed version of MSVC was in French and OSG was compiled
with some US/UK version... (I think it was a "LdrpWalkImportDescriptor()
failed to probe" error)
After installing the US redist installer, we where only able to work in
release.
I've not tried at that time to add the Debug_NonRedist as "private
side-by-side assemblies"...

Did someone already try this ? 
Does it allow to work with debug files ?

If yes It would save me a lot of time...

Pierre.

I'm afraid you will have some false positive, but I've not tested...

I understand pretty well what you would like to do, but I don't know if
ti's possible...
Maybe using the _CRTDBG_DELAY_FREE_MEM_DF (Keep freed memory blocks in
the heap's linked list, assign them the _FREE_BLOCK type, and fill them
with the byte value 0xDD. OFF: Do not keep freed blocks in the heap's
linked list. )

The best way is probably to log every allocation and deletion to a file
using a macro to override the normal new, delete, malloc or free...
Then you will have a complete liste of allocated and liberated bloc...

Maybe it can be of any help ?

Yes it does except I don't know if it allows to go back to the allocated
bloc when it finds some memory leaks...

By the way, just putting before the # include 

>

in stead of after the # include

makes a link error on msvc 2008, complaining operator new is already defined...
So there's maybe something else missing ?

Re: [osg-users] Memory management in OSG

[Pierre Bourdin (gmail)]

Hi,
valgrind is very powerfull if you're on an Linux/Unix environnement, if
you are using MSVC you can use this:

add this bloc at the beginning of each file you want to trace (after all
includes):
#ifdef _WIN32 
# ifdef _MSC_VER
# ifdef _DEBUG
# include 
# undef THIS_FILE
static char THIS_FILE[] = __FILE__;
# define malloc(s) _malloc_dbg(s, _NORMAL_BLOCK, __FILE__, __LINE__)
# define calloc(s) _calloc_dbg(s, _NORMAL_BLOCK, __FILE__, __LINE__)
# define realloc(s) _recalloc_dbg(s, _NORMAL_BLOCK, __FILE__, __LINE__)
# define new new(_NORMAL_BLOCK, __FILE__, __LINE__)
# define delete delete(_NORMAL_BLOCK, __FILE__, __LINE__)
# endif /* _DEBUG */
# endif /* _MSC_VER */
#endif /* _WIN32 */

It replace all allocation routines by the ctr_dbg equivalent.

then add this code in the main to set the proper dbg flags:
// Look at http://msdn.microsoft.com/en-us/library/5at7yxcs.aspx
// for more information about the flags
#ifdef _DEBUG
int flag = _CrtSetDbgFlag( _CRTDBG_REPORT_FLAG );
flag |= _CRTDBG_LEAK_CHECK_DF |_CRTDBG_CHECK_ALWAYS_DF ;
_CrtSetDbgFlag(flag);
#endif 

when you stop debugging you program, it make a memory leaks report in
the msvc output console...

There're also some other tools that look interesting, but I've never
used:
http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx
http://www.cbmamiga.demon.co.uk/mpatrol/

my 2 cents, 

Pierre.

[osg-users] osgcon and textures ?

[Pierre Bourdin (gmail)]

Hi,
I'm trying to convert an ive file that contains some textures to a
collada file, but the textures are not exported at all ?
Did I miss an option ?
I've also tried to convert it to osg file with the same result...
(I'm using openscenegraph 2.6.1)

I was supposing the best way to exchange with someone working with
sketchup would be collada ? 
Do you see a better solution ?
Is there any plugin to read/write google sketchup file ?

Thanks, Pierre.

Hi,
if you're interested in creating particles, you can have a look at
Delta3D which is based on Openscenegraph:
www.delta3d.org

There is a tool for creating particule effects in their utilities (IHM
is based on fltk).

Yes it's working out of shell with osgviewer,  setting it in stereo
mode:

OSG_STEREO=ON
OSG_STEREO_MODE=QUAD_BUFFER

You may also need to activate de quad buffer rendering of your quadro in
the advance settings (or stereo rendering may be, can't remember the
exact name...)
