Re: [osg-users] OSG 2.8.4 - CMake with GDAL (VS9-32bit)
Hi Sanghyung, GDAL is not part of the OSG, it's only used by the OSG's gdal plugin, so you shouldn't be setting the GDAL_INCLUDE_DIR to point the OpenSceneGraph, rather you should be pointing it to whereever you have GDAL headers installed - from the sound of it this will be the 3rd party dependencies folder.

Re: [osg-users] [vpb] How to convert texture file to same coordinate system as height file
Hi Abhishek, I can't recall off the top of my head the gdal command options you require, so to answer your question would have to head over to the gdal website and read up on the commands... So it would be quicker to just go check out the gdal website out yourself, there'll do a much better job of explaining the usage and background functionality than I ever could.

[osg-users] [forum] Collision between 2 MatrixTransform [Coordinates]
Hi,
My name is Leandro and I'm spanish student, I'm working with OSGArt, that is a
library to integrate OSG + ARToolKit in Ubuntu 10.10.
I think the OSG developers has done a great work with OSG and I want thank you.
I'm using OSG with two markers, they control each MatrixTransform and I can
draw objects like balls or cones.
I want to control the collision between these objects, my problem is que
relatives coordinates, I can't get the same coordinates when the objects are in
the same position.
I've tried several things like this:
Code:
osg::Vec3 OsgArt::getWorldCenter(osg::MatrixTransform* mt)
{
osg::MatrixList worldMatrices = mt-getWorldMatrices();
for(osg::MatrixList::iterator itr = worldMatrices.begin(); itr !=
worldMatrices.end(); ++itr)
{
osg::Matrix matrix = *itr;
osg::Vec3 center = mt-getBound().center() * matrix;
std::coutNodemt-getName();
std::coutcenter=center;
std::coutworldMatrix=cameraMatrixstd::endl;
return center;
}
}
or
Code:
computeLocalToWorldMatrix (osg::Matrix matrix, osg::NodeVisitor *nv)
Get the transformation matrix which moves from local coords to world coords.
computeWorldToLocalMatrix (osg::Matrix matrix, osg::NodeVisitor *nv)
Get the transformation matrix which moves from world coords to local coords.
and I also tried this:
Code:
const osg::BoundingSphere bs1 = movingObject-getPat().getBound();
const osg::BoundingSphere bs2 = stationaryObject-getPat().getBound();
if(bs1.intersects(bs2)){
cout Collision OK;
}
Anyone did something similar? ¿Could someone help me, please?
Thank you!
Cheers,
Leandro.

Re: [osg-users] COLLADA plugin: out of memory error.
Hi Alessandro, This sound like a COLLADA problem to me, so the best place to look for a solution will be COLLADA forums and source code. On the OSG side a 75Mb data file is something that load comfortably on an modern PC, so unless there is a specific COLLADA usage bug instigated in our dae plugin I would guess that look for the bug and solution in the OSG will be fruitless. Once you do resove the COLLADA problem I would expect things to work fine on the OSG side. Robert.

I understand the circular reference problem with setting
_userDataContainer to this, so overriding get/setUserDataContainer()
and ignoring _userDataContainer seems like a reasonable solution to me.
Making _userDataContainer a private (not protected) field of osg::Object
prevents end-runs around subclasses that overrides getUserDataContainer().
Having UserDataContainer::getUserDataContainer() return this would
still create a
circular reference as any code that chained calls to use data would
end up in an infinite loop.
The osg::Object serializers automatically write out the
UserDataContainer so is one
example of code that would end up in an infinite loop. One could put
work arounds in
to such code but it's not particularily robust.
Logically I don't think it make sense either, as osg::Object agregates
UserDataContainer, and
UserDataContainer is a osg::Object so should logically do the same.
I don't think the UserDataContainer having an active
getUserDataContainer() is a problem,
but osg::Object::set/getUserValue not working how you'd expect in on a
UserDataContainer is
so I would suggest that this template functions implementation be
tweaked to return use this

unsigned int i = udc-getUserObjectIndex(name);

[osg-users] [osgPlugins] Difficulties to load images from memory
Hello community,
I'm stuck in a perhaps small problem but I don't know which way to go.
I'd like to use the image loaders OSG implements. I've succesfully fetched
images from web links and my own HD. However, now I'm trying to do the same
with an image stored in a string, in main memory.
My OSG version is 2.9.9. The extension for the file is png, and considering s
is the string containing the image, I've tried the following portion of code:
Code:
osg::ref_ptrosg::Image image;
osgDB::ReaderWriter* rw =
osgDB::Registry::instance()-getReaderWriterForExtension(png);
if (rw)
{
osgDB::ReaderWriter::ReadResult rr = rw-readImage(s);
if ( rr.success() )
image = rr.takeImage();
}
From debugging the code, I can see the program executes readImage, but since
rr.success() is false, the image is not taken.
I'm inferring the png plugin doesn't implement this readImage method. Am I
missing something? Would you recommend any solution?
Thank you!
Cheers,
Daniel

Re: [osg-users] Meta-data in core OSG - project started
Hi Robert, hi all, first, thank you for what you've done with this project! I must say i didn't expect the meta data to be in before the 3.0 ... Right now, Sukender is more or less dying under his heavy workload, so I think he reads his emails but unfortunately doesn't have enough time to deeply look into everything you've said. As for me I have two main questions: 1. This first question is not directly linked with the meta feature it's just that i'm still very new to OSG and even more to serialization. How are we going to serialize a custom type meta in our container? I've looked into the UserDataContainer serializer, and I get that when it serializes the _objectList, every object serialializer is called depending on the object type. But I still couldn't figure how and where I should specify the proper serialization for a custom object. 2. When I see the 3 diffent attributes in the UserDataContainer for _userData, _descriptionList and _objectList, I don't know if there's something awkward, or if I don't fully understand the issues. The _userData and _desciptionList are, to me, meta values like any other meta value, so why the special treatment? It makes the UserDataContainer a little heavier to have these three attributes instead of one std::vector. Couldn't we imagine some kind of _userData and _desciptionList subclassing from Object? Maybe this way we could make UserDataConainer inherit from std::vector directly? Instead of being a container containing our real containers.

For backwards compatibility UserData is a osg::Referenced, you can't just assign it as a UserObject as this requires the Objects to be subclassed from osg::Object. You could in their have a custom Obect that holds the a ref_ptr for the UserData but this really would be an ungodly hack. In the case of the Descriptions list it's also backwards compatibility - you can fake compatibiity using a custom UserObject just for holding the Descriptions vector but it's a real hack to do so. So the approach I took actually has far less special treatment than the alternative, and fits very seamlessly in with the old API and it's usage. It makes the UserDataContainer a little heavier to have these three attributes instead of one std::vector. Couldn't we imagine some kind of _userData and _desciptionList subclassing from Object? Maybe this way we could make UserDataConainer inherit from std::vector directly? Instead of being a container containing our real containers. The extra cost a ref_ptr and std::vectorstd::string is pretty small, and in normal usage I woudl expect only a small number of UserDataContainer objects to ever be created so this cost really is likely to be very small indeed. Given we have removed the std::vectorstd::string from osg::Node I would expect the new scheme to result in small scene graphs for everybody.

I tried to put the ImageIO framework in to the Resource group of the OpenSceneGraph Xcode project, but the compilation fails again. I should specify that I'm compiling for iOS simulator, with OpenGL ES 1 enabled, iPhone SDK 4.3. Thank you again, Massimo Hi, can you test the attached ImageUtils.cpp? OpenGL ES doesn't know GL_INTENSITY, so I added an include to osg/Texture, as there are some defines... the ReaderWriterImageIO_IOS.cpp compiles fine on my end, don't know what's wrong. cheers, Stephan Am 10.06.11 16:06, schrieb massimo.ri...@acsys.it: Hi Robert, i'm trying to compile the 2.9.16 version for iOS, at the moment only for the simulator (checked out this morning) but I encountering some errors about GL_INENSITY: /blah/blah/OpenSceneGraph/src/osg/ImageUtils.cpp:473: error: GL_INTENSITY was not declared in this scope /blah/blah/OpenSceneGraph/src/osg/ImageUtils.cpp: error: Semantic Issue: Use of undeclared identifier 'GL_INTENSITY' and about the ReaderWriterImageIO_IOS.cpp: /blah/blah/OpenSceneGraph/src/osgPlugins/imageio/ReaderWriterImageIO_IOS.cpp:16:34: error: ImageIO/CGImageSource.h: No such file or directory /blah/blah/OpenSceneGraph/src/osgPlugins/imageio/ReaderWriterImageIO_IOS.cpp:90: error: CGImageSourceRef was not declared in this scope /blah/blah/OpenSceneGraph/src/osgPlugins/imageio/ReaderWriterImageIO_IOS.cpp:90: error: expected `;' before source_ref /blah/blah/Develop/OpenSceneGraph/src/osgPlugins/imageio/ReaderWriterImageIO_IOS.cpp:116: error: source_ref was not declared in this scope /blah/blah/Develop/OpenSceneGraph/src/osgPlugins/imageio/ReaderWriterImageIO_IOS.cpp:116: error: CGImageSourceCreateWithDataProvider was not declared in this scope /blah/blah/Develop/OpenSceneGraph/src/osgPlugins/imageio/ReaderWriterImageIO_IOS.cpp:126: error: CGImageSourceCreateImageAtIndex was not declared in this scope What's wrong?

Code: osg::ref_ptrosg::Image image;
osgDB::ReaderWriter* rw =

if (rw) {
osgDB::ReaderWriter::ReadResult rr = rw-readImage(s);
if ( rr.success() )

None of the plugins support reading from a string (a string is always
interpreted as a

Try (from memory):
std::stringstream ss(s);
rw-readImage(ss);

Re: [osg-users] COLLADA plugin: out of memory error.
This actually looks like an issue with libxml2, one of the dependencies of COLLADA-DOM. It might be that the bundled version has a bug, which would be an easy fix. What platform are you on? (Windows, Linux, Mac, other) Do you have libxml2 installed systemwide and did the build of collada-dom properly use that system version? What version is it? And, what version of COLLADA-DOM are you using, and with what build system?

Hi Ulrich, Thanks for the answer. Shortly before your answer I found out I could try the istringstream, but I still can't get it to work. The direct conversion is not working out of the box for me, it might be related to the string not being correctly generated (png crashes, jpeg gives a Corrupt JPEG data pop up). I'll keep trying.

Re: [osg-users] OSG based aplication nominated in CG Architect Awards
Hi, Thanks Alsessandro and Ulrich for your feedback :) Asking questions... 1) how do you cap holes when performing dynamic clipping? Every poly behind the holes is viewed by its back face. You only have to fill any back face with an uniform color in a fragment program. 2) is global illumination calculated in real-time as well? No. It's a precalculated radiosity solution, with some optimizations in the scenegraph and lighting info per vertex. 3) how did you integrated panoramas in OSG? Well, we had two ways doing that. At one hand, we developed our own panorama library, that textures any panoramic image in the inside face of a sphere, taking care of projections, texture load, movement control, etc. This is a good choose if you need to integrate in any way the panorama in your 3D scene. By the other side and in the last times we had integrated web browsing inside our own GI system, via awesomium. So most times it were faster and more effective using a page with a flash panorama viewer, like kr-pano. Bye and thanks again!
