[osg-users] Disable maximize button in Win32 window
Hi, I've tried using the following code to disable the maximize button in the window. osgViewer::ViewerBase::Windows wins; viewer-getWindows(wins); osgViewer::GraphicsHandleWin32* hwnd = dynamic_castosgViewer::GraphicsHandleWin32*(wins[0]); HMENU hMenu = ::GetSystemMenu(hwnd-getHWND(), FALSE); ::EnableMenuItem(hMenu, SC_MAXIMIZE, MF_BYCOMMAND | (MF_DISABLED | MF_GRAYED)); The above code is not working for maximize button, but it works well for close button.

Re: [osg-users] My Lines Disapering but Ploygons don't
Hi David, There could be couple of reasons, but I can't work out from your post exactly what is not working and where so I'll provide some general suggestions as to what might be wrong, but given I don't know what the actual problem is I can't provide any suggestions as to how one might fix it. 1) Could it be z fighting? The line is disappearing under the geometry? Try putting the scene in wireframe so that polygons won't obscure hidden lines. 2) Could it be a numerical precision issue? VPB uses local MatrixTransform to place tiles with a local coordinate frame into ECEF to avoid precision issues. 3) Near plan clipping? Robert.

Re: [osg-users] problems with weather
Hi Jose, Are you applying the fog in your shader? Remember that the GLSL spec states that Fog is not applied once a fragment shader has been supplied. Your shader replaces the fixed function shader that applied the fog. Check out: http://www.idevgames.com/forum/showthread.php?t=12436 for a discussion. The fog equation is easy to understand. Check out chapter 6, Blending etc., in the Red Book if you have problems understanding the code in the above link. -Keith On Tue, 13 Jul 2010, Jose Rincon wrote: Hi, I have a scene with weather(in this case with fog) but in the moment I apply a light shader, the weather dissapears.

If we apply triangulation to those few polygons then most models will be unaffected.

Thanks much for that input. I definitely ruled out that my problem was due to
the 64-bit architecture because I was able to reproduce it on 32-bit Linux
using VPB 0.9.10. Using the same tif file, I did not see this problem using
VPB 0.9.7.
I will try your fix to see if that works for my situation. I will report the
results.

Hi Shayne
I'm experiencing a similar problem. The SourceData::readImage(...) method in
\src\vpb\SourceData.cpp gives a destWidth and readWidth of zero which results
in a tempImage of zero size (tempImage = new unsigned
char[readWidth*readHeight*pixelSpace]).
This is due to (I think) a failure of the two pass 360-degree shift test for
intersection of the destination and source bounding boxes. The intersection is
tested for 'valid()', but might still be of zero size. I adapted the 'if
(!intersect_bb.valid())' test as shown below and it seems to work now.
if ((!intersect_bb.valid()) || (intersect_bb.xMin()==intersect_bb.xMax()) ) {
log(osg::INFO,Reading image but it does not intersect destination -
ignoring);
continue;
}
I'm building a simple terrain with BMNG data only. The destination bb is
therefore (-180,180]. The intersection test however generates a valid
intersection for the B1 tiff which is at (-270,-180] at some stage in the two
pass test. The generated intersection is valid, but of zero size and hence the
added condition in the above if.
I attach my SourceData.cpp as reference.

Robert,
After running osgdem in the debugger, it is crashing in gdalrasterband.cpp
where an integer divide by zero is happening. Tracing up further, it appears
that in the method SourceData::readImage(...) in SourceData.cpp, the variable
destWidth is coming in as zero. Interestingly, the first pass through the
loop in that method yields a destWidth of 256. On the next time around, it is
zero which is causing the crash in GDAL.
The .tif file is a file that I have used before with osgdem on another
machined with no problems so I know the image file is good.
I will try to dig further to get more on what's happening...

No matter what database I try to build, I get a floating point

Here is a sample command that fails: osgdem -TERRAIN -geocentric

My question is, has anyone else seen problems with VPB in a similar

why I'm getting this floating point exception. If I use any other

Re: [osg-users] FBX Plugin: animation speed not as expected...
Hi Alessandro and Michael, I have similar timing-related playback errors on a multi-take FBX exported from MotionBuilder. Playback in: OSG 2.9.8 OSG FBX plugin built with: FBX Sdk 2011.2: fbxsdk_md2005.lib / fbxsdk_md2005d.lib FBX exported from: MotionBuilder 2011 QuickTime can move between all twenty(ish) animation takes and play them with proper timing. The only oddity is that after each animation plays, there is a variable length dead space on the playback timeline in which the model does not move. For example, the first 40% of playback is animated normally, then it stays in a static pose for the remaining 60% of the timeline. Playback is different using the osgViewer modified for FBX playbacks and changing takes/animations when a key is pressed. Calling playAnimation() moves the character to the correct initial pose but he does not move. In the debugger, the animation durations appear correct (e.g., 12 seconds) but for most takes the model is motionless the whole time. For a few takes, after a long pause the model eventually runs part of the animation at very high-speed, in the way that Alessandro's 3-bouncing-balls model played at high speed. Then even these return to a static pose for the remainder of their play time. My best guess is the timing is thrown off and this is somehow compounded across takes. The plugin has FPS hard-coded to 25 fps so we tried exporting at both 25 fps and 30 fps with only slightly varying results. I can email a sample file to demonstrate this (~15 MB).

I've downloaded the latest source code of the FBX plugin and osgAnimation from svn but, I'm still experiencing different playback speed with respect to QuickTime moreover I have also problems with the animations themselves. As I said I'm using the latest code for FBX plugin and osgAnimation, on the other hand I'm using OSG 2.9.6 for all other plugins and libraries, so my question is: beyond the FBX plugin itself and osgAnimation what else could cause the problems with animations I'm experiencing? (ie not only speed, but also wrong/bad animation playback in general) By the way, I tried with both QuickTime and the ViewScene example that comes with the FBX SDK, they both play every model correctly. Talking about test models, I tryed: humanoid.fbx: model messed up during animation the 3-bouncing-balls model (sent to Michael some days ago): animation played at exagerated speed and now I have two more humanoid models one of which has the same problems of humanoid.fbx and the other seems to be missing some starting and ending frames. I'm going to send them to Michael. Regards.

Re: [osg-users] Fwd: Re: floating point exeption in VPB...
Just a follow up email...the fix that Bernardt proposed in SourceData.cpp of
the VPB code, seems to have fixed the problem. I don't have any issues
building my database with VPB 0.9.10 now. This seems like a pretty blatant
problem so I'm somewhat surprised that this problem hasn't come on the radar
screen of the OSG community in general...

Bernardt,
Thanks much for that input. I definitely ruled out that my problem was due
to the 64-bit architecture because I was able to reproduce it on 32-bit
Linux using VPB 0.9.10. Using the same tif file, I did not see this problem
using VPB 0.9.7.
I will try your fix to see if that works for my situation. I will report the
results.
Your contribution is most appreciated...

Hi Shayne
I'm experiencing a similar problem. The SourceData::readImage(...) method in
\src\vpb\SourceData.cpp gives a destWidth and readWidth of zero which
results in a tempImage of zero size (tempImage = new unsigned
char[readWidth*readHeight*pixelSpace]).
This is due to (I think) a failure of the two pass 360-degree shift test for
intersection of the destination and source bounding boxes. The intersection
is tested for 'valid()', but might still be of zero size. I adapted the 'if
(!intersect_bb.valid())' test as shown below and it seems to work now.
if ((!intersect_bb.valid()) || (intersect_bb.xMin()==intersect_bb.xMax()) )
{
log(osg::INFO,Reading image but it does not intersect destination -
ignoring);
continue;
}
I'm building a simple terrain with BMNG data only. The destination bb is
therefore (-180,180]. The intersection test however generates a valid
intersection for the B1 tiff which is at (-270,-180] at some stage in the
two pass test. The generated intersection is valid, but of zero size and
hence the added condition in the above if.
I attach my SourceData.cpp as reference.

Bernardt

Robert,
After running osgdem in the debugger, it is crashing in gdalrasterband.cpp
where an integer divide by zero is happening. Tracing up further, it appears
that in the method SourceData::readImage(...) in SourceData.cpp, the
variable
destWidth is coming in as zero. Interestingly, the first pass through the
loop in that method yields a destWidth of 256. On the next time around, it
is
zero which is causing the crash in GDAL.
The .tif file is a file that I have used before with osgdem on another
machined with no problems so I know the image file is good.
I will try to dig further to get more on what's happening...

Hi Shayne,
I develop under 64bit system and haven't encountered any floating point
exceptions issues with 64bit build of VPB.
Could you please run osgdem in a debugger and see what happens. Could you
also
update to svn/trunk for OSG and VPB to see if the problem persists.
Robert.

All,
I'm using VPB 0.9.10 along with OSG 2.8.2 on a system that is using
64-bit Linux (Fadora core 10) i386. Both packages were built from source.
No matter what database I try to build, I get a floating point
exception when running osgdem. I know the DTED and imagery are good
since I've built VPB databases with this content on a windows 32-bit
system.
Here is a sample command that fails: osgdem -TERRAIN -geocentric
-PagedLOD -whole-globe -t wholeearthtexture.tif -l 10 -o output.ive
My question is, has anyone else seen problems with VPB in a similar
environment.
Re: [osg-users] Human 3d model animation/motion
Hi Glenn, As if now, I was hoping to use open source tools for at least the conversion to osg part. I did some reading following Jean's and Martin's post and I kind of followed the following: 1) Since I am trying to use models in my simulation, I wouldn't want to spend too much time on creating rigged+animated models in blender/3ds etc. I would want to buy/use already rigged+animated models. 2)In Blender, to export, I presume Collada 1.4 is the best format to pick in order to preserve animations and skins. 3) The part I am having trouble getting figured out is this: Assuming I have a model in dae format (collada). I didn't find any example where this can be used in a simulation straight away taking advantage of the animation already present in the model. I am already working on an osg app using visual studio and was not sure if I can use just the character animation part of delta 3d as osg satisfies my other requirements so far.

Re: [osg-users] Human 3d model animation/motion
Hi Sanat, If you want to use blender the best way to export is to use osgexport for blender IMO. I did osgAnimation and osgexport for blender at the same time. If you plan to use 3dsmax or other I guess the best is to use collada. You can get osgexport here http://hg.plopbyte.net/osgexport/ with mercurial like this: hg clone http://hg.plopbyte.net/osgexport/ You will find some 'template' data in the repository as example ready to export and usable in osg.
