Re: [osg-users] Move object with callback
Hi, if you don't want to use callbacks you can split the viewer->run() into !done and viewer->frame(); And then just update a PositionAttitudeTransform or MatrixTransform that sits above your node you want to move between frame calls. jp On 21/04/10 09:54, daniele argiolas wrote: Hi, in my program I've external inputs that change the position of my object.

Re: [osg-users] openGL error with osgEarth?
Hi Jason,
In fact, I create the map through program.What the program does is that as and
when some new tif file arrives at particular folder which I am monitoring
continuously thru callback, I add the file to the already created map. It works
well for some 2-3 tile addition. When it goes beyond that it throws the openGL
error. Have a look at my code. Is there any other way to do the same.
Akilan. A
Code:
class monitorCallback : public osg::NodeCallback
{
public:
monitorCallback(osgEarth* map)
{
_map=map;
}
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
//
// look for any new tif arrival at specific folder
//
.
.
if(new_tif)
{
sprintf(name, "tile_%d", tif_cnt);
osgEarth::Config conf;
conf.add("url", new_tif);//new tif name with relative
path
_map->addMapLayer( new osgEarth::MapLayer(name,
osgEarth::MapLayer::TYPE_IMAGE, "gdal", conf ) );
}
}
osgEarth::Map* _map;
};
int main(int argc, char* argv[])
{
_chdir(curr_dir);

}

[osg-users] Simplifier does nothing if smoothing set false
I have experimentally determined that a Simplifier with _smoothing set to false will not accomplish anything. The number of verticies always stays the same: osgUtil::Simplifier simp; simp.setSmoothing(false); // set true to actually do something. simp.setSampleRatio(0.5); root->accept(simp); If smoothing is turned on, then decimation takes place. Can anyone reproduce this? I'm looking at the code but haven't determined what is generating the necessary side effect with smoothing turned on. Perhaps the SmoothTriangleFunctor is helping?

Hi Claus, You can setup your camera view matrix using : viewer.getCamera()->setViewMatrix(matrix) or viewer.getCamera()->setViewMatrixAsLookAt(eye, center, up) The second one is a good start. For the meaning of the parameters eye, center and up, ask your friend (google ^^) about gluLookAt.

Re: [osg-users] [3rdparty] Digital elevation model visualization
Hi Lucie, I would recommend looking at both osgEarth and VirtualPlanetBuilder for displaying geospatial data in OSG. Both VPB and osgEarth are built using OSG's osgTerrain library so the resulting scene graphs are similar. The main difference is that VPB produces optimized static scene graph tiles from input geospatial data and osgEarth produces the scene graph at runtime from a variety of different sources (local geospatial data, WMS servers, TMS servers, etc). I'm one of the developers of osgEarth, let us know if you have any questions. Thanks!

Re: [osg-users] [3rdparty] Texture applied in modelling tool not showing up
Hi Adam, Don't worry about inexperience. The people around here are very friendly and will only generally respond negatively if you display no desire whatsoever to try and debug things yourself, or if you post a heap of code and ask others to debug it for you. This was not your case, so you're fine :-) 1) As a newbie, I assumed reading in the .DAE file was self-contained and the textures would "magically" display themselves. Is this assumption naive and misguided? (Yes/No) The dae format refers to, but does not embed, textures. So your textures need to be found and then read by the loader. So I suspect the problem is paths. A dae file is XML, so you can open it in a text editor and read it to see where it expects to find texture files. Additionally, and this is useful OSG debugging info in general, you can turn on additional debug info by setting the environment variable OSG_NOTIFY_LEVEL=DEBUG. This will print lots of things, among which the plugins that the app will use to load your file, where it looks for the texture files, etc. This, I believe, is mentioned in the Quick Start Guide. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] [3rdparty] Texture applied in modelling tool not showing up
Hi, I hope I am posting to the proper forum. I would like to ask a very basic question. If there is something I missed in the FAQs/forums, I apologize in advance and I will look again. I created a textured scene with a 3D tool (Truespace) and exported the scene as a Collada (.DAE) file. I then tried to render this scene using osgDB::readNodeFile method and the usual osgViewer code. The scene displays but none of the textures I applied in the modelling tool are present. I also tried to enable texturing using set texture mode methods, but to no avail. Clearly the issue is my inexperience and has nothing to do with OSG. My two questions are: 1) As a newbie, I assumed reading in the .DAE file was self-contained and the textures would "magically" display themselves. Is this assumption naive and misguided? (Yes/No) 2) If the answer to question 1 is Yes, what additional steps do I need to do or what forum/web site should I read to resolve this? Just as an FYI, I am aware of and have read some of texturing information in the OSG QuickStart guide. I appreciate any help you can give me and I apologize if this is a RTM question. Thank you!

give the error
A first chance exception of type 'System.AccessViolationException' occurred in

I am not sure how to debug this because I believe this is one of the first

Hi Suvajit, From your description I suspect that your problem is caused by the osg object cache. try osgDB::Registry::instance()->clearObjectCache(); before the ReadFile() to see if that's the problem. If that helps you might want to just supress the usage of the cache for this readfile call: osgDB::ReaderWriter::Options* opt = osgDB::Registry::instance()->getOptions(); if (!opt) opt = new osgDB::ReaderWriter::Options(); opt->setObjectCacheHint(osgDB::ReaderWriter::Options::CACHE_NONE); osgDB::Registry::instance()->setOptions(opt); readFile() opt->setObjectCacheHint(osgDB::ReaderWriter::Options::CACHE_ALL); osgDB::Registry::instance()->setOptions(opt); Cheers, Laurens.

Hi Dario, This sound like but unfortunatly don't works. I've exported the variable (export OSG_OPTIMIZER="OFF") but the result is the same as above.

Re: [osg-users] [osgPlugins] FBX conversion lost "NULL" nodes.
Hi Dario, I've exported in FBX a scene structured as the above example and then I have converted this file into an OSG file (osgconv). The OSG file don't contains the NULL nodes but only the object_with_mesh. This is not specific to the FBX loader. osgconv runs the osgUtil::Optimizer on the loaded graph (loaded from the input file) before outputting the new file, and the Optimizer can reorganize the scene graph in some ways. For example it will remove nodes it thinks are redundant. We generally set OSG_OPTIMIZER=OFF in the environment before running osgconv so this does not happen. In our case, we often use DOF nodes with no geometry under them to position cameras / lights on models, and the Optimizer removes those by default (because it thinks they're useless if they have no geometry under them). So I suspect something similar is happening to you. Try setting OSG_OPTIMIZER=OFF to see if that helps.

[osg-users] [osgPlugins] FBX conversion lost "NULL" nodes.
Hi, Converting a FBX file (2010.2) into an OSG I saw that some "NULL" nodes are lost. For example I've tried a convertion of a simple scene: OBJECT |OBJ_WRAPPER |object_with_mesh OBJECT and OBJ_WRAPPER are simple "NULL" nodes, typically used to group others object. I've exported in FBX a scene structured as the above example and then I have converted this file into an OSG file (osgconv). The OSG file don't contains the NULL nodes but only the object_with_mesh. Analyzing the FBX file, I think that this happens when to a NULL node is applied no one transformation. OBJECT and OBJ_WRAPPER aren't inserted in the OSG file if they have FBX properties like: Property: "Lcl Translation", "Lcl Translation", "A+",0,0,0 Property: "Lcl Rotation", "Lcl Rotation", "A+",0,0,0 Property: "Lcl Scaling", "Lcl Scaling", "A+",1,1,1 Property: "Visibility", "Visibility", "A+",1 Instead, if they have some non-zero Translation field or others properties, then they are inserted in the OSG file as MatrixTransform node. So, this behavior can be an optimization but the OSG file not always respect the original hierarchy. Is there any way to keep the original hierarchy? Thank you!

Re: [osg-users] [osgPPU] HDR example: wrong average luminance?
Hi Luca, Allen, Josselin, ok, I found the bug. as I said the bug is not really a bug it is more or less slightly unclear definition of glsl. The problem was to use texture2D method instead of texture2DLod to get value from mipmaps. Actually in the definition of glsl texture2DLod is mean to be used only in vertex shaders. For whatever reasons texture2D do not really accept the last parameter, so one do always read the first mipmap level, instead of the last one. Another problem was not to clamp the resulting luminance to 0 on negative values. Negative values happens when everything is black, so the log(0+epsilon) became negative. On nVidia hardware texture2DLod can be also used in fragment shaders. Unfortunately I have no clue about ATI hardware. I placed some extra glsl extensions into the shader code, to activate this behaviour also an ATI cards. I found this info on a forum about game development. So, maybe this helps. I debugged now the HDR example and it seems to work perfect. However I am not sure how it will work on ATI cards, I hope it would also work perfect :) New changes are submited into osgPPU-0.4.1 repository, the svn trunk is not patched with this changes for now. I will do this in the next days.

Re: [osg-users] Refreshing a Scenegraph
HI Suvajit,
The debig message is telling you that it's just reusing the
osgViewer::Scene object, not that it's not re-assigning the scene data
itself. The Scene object is a background class used to manage
multiple views sharing the same Scene.
As for the no visual changes, well are you calling frame afterwards?
You won't see any changes unless you re-render the scene.
Robert.

Re: [osg-users] Help for control of Text Labels on HUD type display OFF/ON/BLINK and text
Hi Tim, As a general guide I would recommend picking the simplicist way to implement a solution first and it perform fine then stick with it, don't worry too much about performance. Times to worry about performance are when you've already established a bottleneck through testing and now need to address it, or that you know you are about to throw 10's of thousands of objects at the scene graph and need to do it most efficiently. In your case a simple HUD won't take either the CPU or GPU and an osg::Switch and associated update callback are very unlikely to provide any type of bottleneck. Robert.

[osg-users] [osgOcean] Iam in a puzzle about the realization of osgOcean's 'Glare effect'
Hi,
I saw the code in 'OceanScen.cpp', that 5 cameras in
'osgOcean::OceanScen::_glarePasses' were used to render the glare effect.
But I saw the realization code in "water.frag" is just as bellow:
if(osgOcean_EnableGlare)
{
float lum = luminance(lumColor);
gl_FragData[1] = vec4(lum);
}
And it looks like that the cameras in 'osgOcean::OceanScen::_glarePasses' were
not been used anywhere. Will tell me why?
Thank you!
Cheers,
Tian

[osg-users] Refreshing a Scenegraph
Hi,
I have attached a GUIEventHandler to osg::Viewer to refresh the model if the
content in the file has changed.
Like whenever refresh action is called I do the following:
osg::ref_ptr root = osgDB::readNodeFile("path_to_shp_file");
viewer->setSceneData(root.get());
I have to reread the source file as the content in it has changed.
But while setting the scenedata OSG states:
View::setSceneData() Reusing exisitng scene01EF1108
and hence no visual changes due to change in scenegraph is not perceived.
It is obvious that I cannot refresh a viewer scene data just by overwriting it
as the reference to existing root still exists. What is the smart way of doing
this like as in updating view when model changes in MVC ?
...
Thank you!
Cheers,
Suvajit
