Re: [osg-users] floating point exeption in VPB...
Hi Torben I checked out and successfully recompiled an unmodified VPB (trunk rev 1015) with GDAL 1.7.2 (GDAL 1.7.2, released 2010/04/23) and MS VS8 a few minutes ago. As far as I remember VPB also compiles with the version of GDAL provided with FWTools (GDAL 1.7.0b2, FWTools 2.4.7, released 2010/01/19). I haven't tested other compilers though. Note that the GDAL version strings I give are the result of gdalinfo --version Kind regards, Bernardt Torben Dannhauer 08/10/10 8:58 AM Hi bduvenhage, You saif you are using GDAl 1.7.x ..

Re: [osg-users] Fwd: Re: floating point exeption in VPB...
Thanks Robert I've used the latest version of vpb (and osg) and successfully built the blue marble terrain that previously led to a memory access violation and program crash. It does indeed seem that the problem is fixed now :-) Regards, Bernardt Robert Osfield 08/09/10 9:50 PM Hi Bernardt, Shayne et. al, I've now reviewed Bernadt's change and understand the need for this. To make the required test clearer I feel that it would be worth making an additional test of a valid GeospatialExtents in the form of a GeospatialExtents::nonZeroExtents() method which, this would then replace the use of valid() method in the SourceData code. I have now implemented, tested and checked in this change. I don't have any databases that trigged the numerical error so could you guys do an svn update on the OSG and VPB and test these changes out.

[osg-users] OpenSceneGraph + NVIDIA Optix == true?
Hi all. Is there anyone on the list that could elaborate on this: http://developer.download.nvidia.com/presentations/2009/SIGGRAPH/Siggraph-SceniX-2009.pdf I get the feeling that it is possible to take an OpenSceneGraph app and use Optix to render the scene to get high-quality Raytraced images... If so, its nothing but a huge leap forward, being able to render hi-quality stuff to get screenshots, movies using the same code/app as in realtime. Sounds a liiittle bit to good to be true if you ask me. I know that RedSDK has this support, but thats inside the same scenegraph. This seems to work through a mechanics named SceniX.

I should also mention that it wouldn't be using the same code as in realtime. You have to write the OptiX code to get the ray tracing done. It's not hard to do, from the examples I've seen, but it's not just plain old scene graph code either. What they're showing off is the ability for SceniX to manage the scene structure, but actually doing the rendering using ray tracing. Their OptiX engine does run interactively, but it uses progressive refinement. If the scene to be rendered is complex enough, you don't get a pretty picture at first. You get a really grainy one instead. If you keep the camera still, it slowly improves as more rays are cast to resolve the scene. It makes a pretty cool demo, but its still got a while to go before it replaces polygonal rendering for interactive apps. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

To me it looks like the boost exceptions are initializing themselves (to
have enable the global functions like current_exception etc.) by throwing
around some exceptions. Now the MSVC exception handling implementation (as
far as I read) uses a special errorcode (-*529697949* , In *hex*, this is
0xE06D7363) internally to determine if an exception occured. With this
errorcode set (from the unevil exception during initialization) the
LoadLibrary call exits with an error, just because the internal errror flag
is set to the C++ exception Magic Number...so far my ideas, I might be
totally wrong.
However, looks like a openvrml problem rather then an osgPlugin one.

Thomas

One more thing - if the exception is from the filesystem module, it
could mean that boost is told to open something that it cannot find.
What kind of exception are you getting?

Re: [osg-users] OpenSceneGraph + NVIDIA Optix == true?
Anders Backman wrote: I think you are wrong, having ray tracing in the same scenegraph which you use for real-time rendering is not because you want to use it for the every day simulator. The purpose mainly (until it is fast enough) is for engineering, movie making, screenshots etc. where real time is not an issue. I misunderstood you. I thought you were referring to getting high quality ray traced images at interactive rates. OptiX can't do that (yet). Indeed, one of the demos at SIGGRAPH this year was a CAD company that had integrated OptiX into their CAD renderer. The end result lets you position your viewpoint interactively, using an interactive, but grainy rendering. Then, once you let go, it gradually refined the image to a high quality rendering over time. It's an interesting way to provide both interactivity and high quality at almost (but not quite) the same time. Generating movies of high-quality from a simulator without the need to write a single line of code is not a bad thing!! Its a request you get on a daily basis when you sell simulators. Nobody's saying it is a bad thing :-) Anyway, I just wondered if someone had played around with Optix and seen any relation to OSG. If they can mix SceniX and OptiX, I don't see why someone couldn't mix OSG and OptiX. I haven't done a lot of digging, but I don't see why it wouldn't be possible. As you said, it's just a matter of getting the scene data there. No idea how much work it would be, though. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

You are getting bad_alloc from Boost, that type of error usually means that: a) you have run out of memory (not likely) b) allocation failed due to corrupted heap. My bet is on the second possibility - likely the DLL heap (which is separate for each DLL) is messed up. I would check the compiler switches related to DLLs and make absolutely sure that there is no mismatch between debug and release libs, even for dependencies of OpenVRML - everything needs to be the same. Debug uses different memory allocation code and such crashes are pretty much the symptom of mismatched libs. Can you build some of the OpenVRML demos?

[osg-users] osgEarth processing problems
Hi,
I write a map.earth file according to the original examples of .earth files in
osgEarth project. The map.earth file is as follows:
map name=tkm type=projected
heightfield name=terrain-dem driver=vpb
url C:\Test.ive /url
/heightfield
/map
where “Test.ive” file is generated by VPB0.9.10 and it’s a terrain file using
Gaussian projected coordinate system.. Therefore, the type in .earth file is
projected.
Then in my win32 console program, I read the map.earth in my project, the codes
are as follows:
// header files …
……
int _tmain(int argc, _TCHAR* argv[])
{
int num =1;
char* path = D:/maps.earth;
osg::ArgumentParser arguments(num,path);
osgViewer::Viewer viewer(arguments);
osg::ref_ptrosg::Node Test_node =
osgDB::readNodeFile(“D:/maps.earth”);
viewer.setSceneData(Test_node.get());
viewer.realize();
std::coutpathstd::endl;
viewer.run();
return 0;
}
The compilation is correct. When debugging the code, I find the Test_node point
is not empty. However, the ive terrain file is not shown in the whole scene. In
the whole scene, there is nothing but the blue background. I use cow.osg to
replace Test.ive for tests. However, I cannot find the cow, either.
I wonder what is going on with my osgEarth, are there some problems with my
coordinate setting or something else? Plus, all the osgEarth dll libraries have
been put in the environmental path. Thank you.
Thank you!
Cheers,
ting

Re: [osg-users] osgEarth processing problems
Ting,
I'm not sure what a Gaussian projected coordinate system is.. can you
elaborate?
To use the VPB driver, you have to specify several additional options so
that osgEarth knows how to load the model. Look at the docs here:
http://www.osgearth.org/wiki/TileSourcePluginVPB and look at the
vpb_earth_bayarea.earth sample.
I also suggest you set the environment variable OSGEARTH_NOTIFY_LEVEL=INFO
and see if the output gives you any clues.
