[osg-users] osgEarth fading effect?
Hi, Similar to osgEarth which provides to set fading effect to the terrain tiles, could it be is possible to get the same effect directly from osg alone and how? Bcoz, to exploit that feature from osgEarth, it puts some constraints like the terrainDB should be generated with --terrain options and some other split level specifications. By passing all those constraints I wud like to see thru my terrainDB with the fading effect. I hope dat dis s not just to do with pagedLOD.

Re: [osg-users] Add a color node in the scenegraph?
Hello, I tried what you said, but it doesn't work.
Do you see an error in my code ?
Code:
osg::ref_ptrosg::Sphere sphere = new osg::Sphere(osg::Vec3f(0.0, 0.0, 0.0),
.5f);
osg::ref_ptrosg::ShapeDrawable sphereDrawable = new

osg::StateAttribute::ON);
osg::ref_ptrosg::Geode sphereGeode = new osg::Geode();
sphereGeode-addDrawable(sphereDrawable.get());
osg::Matrix I = osg::Matrix::identity();
osg::ref_ptrosg::MatrixTransform mtI = new osg::MatrixTransform(I);
mtI-addChild(sphereGeode.get());
double x = 0.0;

Re: [osg-users] Quadro FX 2500M weird polygon edge lines
Hi Chris, This is almost certainly a driver bug, so if can't change the driver your options are likely to be pretty limited.

Re: [osg-users] [osgPlugins] gecko plugin
Hi Wang Xianghua, I have tried building osgdb_gecko on windows and found that the xulrunner prebuilt SDKs were not suitable. You should download the 1.8 source code, for instance, xulrunner_1.8.1.16, and obtain complete packages from it. BTW, why not have a try of the new osgQt library and osgbrowser example.

Re: [osg-users] [osgPlugins] gecko plugin
Hi Wang, I wouldn't recommend using the gecko plugin as gecko has turned out to be rather a beast to get working across platforms. In OpenSceneGraph svn/trunk and the 2.9.x series there is support for using QWebKit, so I'd recommend using this rather than the gecko plugin as Qt is much easier to get working across platforms.

Re: [osg-users] run-on-demand
Hi Paul, I just did a test on my Kubuntu system and used top to track the CPU utilization and found that when spinning the cow.osg CPU usage is very low, but when I stop the model spinning the CPU usage goes up to 100%. Ooops looks like the code is going into a spin lock. However, if I enable the limiting of the frame rate CPU usage when using run-on-demand goes back down to near 0: osgviewer --run-max-frame-rate 100 --run-on-demand cow.osg So my guess is that the frame loop, when runing on demand, is just running in a continuous loop checking where a new frame is required. The solution to high CPU utilization is likely to be just to add a sleep when on demand rendering is enabled and there is nothing to do. I'll look into this. Robert.

Re: [osg-users] osgEarth fading effect?
Hi Akilan, If you're talking about the FadeLayerNode in osgEarth it's basically just doing a shader that blends multiple texture units together. The osgFX::MultiTextureControl does something similar without using shaders is so that we could support fading along with imagery that contains an alpha channel. You should be able to use the shaders for the most part and apply them to a regular VPB model.

[osg-users] How to not show textures
Hi everyone,
I'm having a tough time preventing textures from showing in the scene. I've
tried the approach explained in the QuickStartGuide, but I'm obviously missing
something bigtime...
Here is the main part of the code:
Code:
unsigned int mode = osg::StateAttribute::OVERRIDE | osg::StateAttribute::OFF;
osg::ref_ptr osg::StateSet state = sceneNoColor-getOrCreateStateSet();
for( unsigned int ii=0; ii 12; ii++)
{
state-setTextureMode( ii, GL_TEXTURE_1D, mode );
state-setTextureMode( ii, GL_TEXTURE_2D, mode );
state-setTextureMode( ii, GL_TEXTURE_3D, mode );
}
Frankly, I wouldn't mind removing the textures alltogether, but I'm not sure
how to do that efficiently.
I would very much appreciate any suggestions about how to make this work.
Thank you in advance.
Inos

Re: [osg-users] osgIntrospection serialization
Hi Paul, I'm working on extact the same issue! My plan was to finish my cluster implementation and then discuss with the community if some parts could be reused to add cluster functionality to osg something like osgCluster. At first I tried to use boost::asio for my project, because the usage seems quite simple and it has great features (e.g. sending my serializeed stream over network would be only some lines of code), but I did'nt managed to get boost::asio compiling with my osg application.

Robert, Unfortunately, this causes another problem. Now when I do this: $ osgviewerd --run-on-demand --window 0 0 400 400 cow.osg The window doesn't rerender on resize or repaint. I would expect that a window resize would set a need to render flag. Thanks for you help.

Re: [osg-users] 3D model fomat
Hi Generally in many cases yes IVE's will/can help improve your runtime performance especially load time, when converting from other formats such as 3DS, FLT to IVE optimizations can be done that can aid the run time as well , but could model a lot of that as but most folks don't model that way these days, it's a skill that being lost Whatever the run-time you use it is generally found that the native binary format IVE in the case of OSG will typically outperform the generic modeling formats Having said that how you model a feature or set of features can also dramatically improve or hit the runtime performance whether or not you use IVE etc Gordon Tomlinson Product Manager 3d Technology Project Wyvern Overwatch(r) An Operating Unit of Textron Systems -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Yong Wang Sent: Wednesday, April 14, 2010 10:39 AM To: OpenSceneGraph Users Subject: Re: [osg-users] 3D model fomat Hi, Gordon: Thanks a lot for your quick response, does that mean IVE provides better performance for runtime?

[osg-users] Should I stop the rendering thread when updating the scene graph? I suppose not, but..
Hi,
I am a relative new OSG user and I am developing OSG ActiveX application.
My C++ project is compiled in VS2008 with /CLR (I am using .NET platform for
the Web services communication).
In my application the rendering (viewer-frame()) is running in a separate
thread which is started when the application in initialized. The OpenLocalFile
function (running in the main thread) is responsible for loading scenes from
the local disk.
The following is the function source code:
void CDl3dViewerCtrl::OpenLocalFile()
{
// sigal the rendering thread to stop and wait for it
StopRenderingThread();
// clean the model (except of the service nodes)
int cnt = _root-getNumChildren();
_root-removeChildren(NUMBER_SERVICE_NODES, cnt - NUMBER_SERVICE_NODES);
// Load a new model
osg::ref_ptrosg::Node node = osgDB::readNodeFile(_loadedFile);
if (node.valid())
{
node-setDataVariance(osg::Object::DYNAMIC);
_root-addChild(node.get());
_viewer-setSceneData(_root.get());
// Back to home position to see the whole scene
_viewer-getCameraManipulator()-computeHomePosition();
_viewer-getCameraManipulator()-home( 0.0 );
_viewer-realize();
}
else
{
::MessageBox(0, A2BSTR(Fail to open file.), LError, MB_OK);
}
// run the rendering thread
StartRenderingThread();
}
My problem is that without StopRenderingThread() the code doesn't work.
Actually it works, but after number of sequential calls i am getting debug
assertion: Expression: (this-_Has_container(), 0). That call stack presented
below.
I suppose that is normal practice to make changes in the scene graph when the
rendering is running, but in my case it makes problems.
I'd happy to get any suggestion/ideas regarding this problem.
Thanks and Best Regards
Oleg
Some additional info:
I took Wang Rui http://markmail.org/message/shdd6p5lqcqg62bf sample as a start
point for my application.
The same problem is reproducible in the original (Wang Rui) ActiveX, that is
not /CLR.
It also occurs when the ActiveX is running in my tester (ActiveX container), so
I think the Internet Explorer is not guilty here.
It is happing at least on four computers (Vista/Windows 7).

Re: [osg-users] FBX plugin with FBX SDK 2011.2
Hi Michael, I've now updated the FBX plugin to compile with the latest FBX SDK. Unfortunately this breaks compatibility with previous versions so next time you get the plugin you'll need to install version 2011.2 FBX SDK if you want to recompile the plugin. Wouldn't there have been a way to keep it compatible with both? (#ifdefs or something) Also, will the new sdk/plugin read older files (that the old plugin read fine)? I guess the answer is yes, otherwise you wouldn't have modified the plugin in that way, but then where does the incompatibility come from? Just curious.

Re: [osg-users] using draggers to move objects in a scene
Hi, I created a scene consisting of a man holding onto a book. Now I am trying to get the scene to act as follows: * when i pick the man, the book moves with it * when i pick the book, it moves without the man, and actually detaches from it (if i move the man again another time the book will not move) I tried to use some dragger (axis transform ,tabBox) method but to no avail - everytime the object i move is being duplicated, and i cannot move the man with the book. any ideas on how to to it? I'm using visual studio 2008 with the osg 2.8.0 If my question is in any way missing or unclear, please let me know and i'll elaborate. P.S. : The node tree i used to do it is: root -- body -- all the body parts (head, arms, legs etc...) each of them has it's own tranform root -- book (also with it's own transform) ... Thank you!

[osg-users] Issues drawing interactive line
Hi, In my windows machine i am using osg and qt based framework for making a small application. I am able to draw lines as AXES in my application, but when i try to draw line using mouse. It does not work. The same code of line drawing using mouse works on windows 7 to my surprise. it also works on any machine having external graphics card. I am using osg 2.8.2 and Qt 4.6.1. Anyone having any idea? Regards, Nem ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] FBX plugin with FBX SDK 2011.2
Wouldn't there have been a way to keep it compatible with both? (#ifdefs or something) I would have if I could have without making the code nightmarishly complicated but the structure of how animations are presented by the SDK is very different now. Also, will the new sdk/plugin read older files (that the old plugin read fine)? I guess the answer is yes, otherwise you wouldn't have modified the plugin in that way, but then where does the incompatibility come from? You guess correctly, yes old files read fine :) I should have said the latest SDK breaks compatibility with previous versions* of the plugin code*; there's no break in compatibility with any .fbx files. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] 3D model fomat
Essentially, it REALLY depends, because some formats are text based while others may be proprietary file types. Some are designed for animation, others may include textures. It might help to try experimenting with some of them. See which ones you like. -Masoug ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] strange Matrix interface
Hi, can somebody explain to me why in Matrixd/Matrixf there is a getRotate, setRotate, getTrans, setTrans, getScale ... but no setScale? is there a reason for this? and why do i have to pass a matrix to the (non-static) bool Matrix::invert method? Cheers, Jason PS: a Matrix MatrixTransform::getMatrix (no const reference) would also be nice, so i could operate on the contained matrix directly if i wanted to and would not have to copy it with getMatrix and copy it again with setMatrix...) ithrak (Jason Fisher) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=26806#26806 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] FBX plugin with FBX SDK 2011.2
Hi Michael, You guess correctly, yes old files read fine :) I should have said the latest SDK breaks compatibility with previous versions/ of the plugin code/; there's no break in compatibility with any .fbx files. Great, thanks, that clears it up. Guess I'll install the new SDK. Will your modified CMake find file find the required version (2011.2) even if both 2010.2 and 2011.2 are installed? I'll probably keep 2010.2 installed so I'm able to compile OSG 2.8.3...
