Re: [osg-users] !Present3D GUI
Hi Bruce, On Fri, Feb 12, 2010 at 5:49 PM, Bruce Wheaton br...@spearmorgan.com wrote: The Present3D wiki asks for contributors. If it would be acceptable for a GUI to be written in juce then I would like to help. Juce works as GPL or under a commercial license. That does mean an OSG licensed GUI would probably not be possible, although I can ask the developer. Maybe not an issue, as it's an app, not library? I'm not familiar with Juce. Why Juce rather than other GUI toolkits? W.r.t license Present3D is GPL, while osgPresentation and the p3d plugin that provide the bulk f the functionality are OSGPL. Having a GPL'd library ontop of osgPresentation that adds GUI might be OK. However, there are other alternative GUI libs that LGPL'd, such as Qt, so I'd wonder why these wouldn't be better. I terms of functionality Present3D itself my plans has been to refactor osgPresentation to provide a better object model and then scripting on top of this, and have GUI elements that sit on top of this for create/editing presentation objects. The GUI elements would be a mix of fully 3D elements using osgWidget/osgManipulator and 2D elements such as file browsers. Present3D is used extensively as immersive (stereo) presentation tool, so being able to stay in fully immersive (i.e. not 2D elements at all) is important when fine tuning a presentation. I would use an offshoot of the code commerically. If we can get the osgPresentation layer right and avoid too much deviation ontop of this hopefully we'd be able to have a family of presentation tools that would be pretty compatible with each other. If some of these are commercial then great, especially if they can drive forward the osgPresentation layer and provide better tools for generating content.

[osg-users] Enhancement of osgDB::serializer
Hi Wang, I managed to get the serializer working. I have some proposals to enhance the serializer: 1. It is only possible to serialize objects inherited from osg::Node or Images. Classes just inherited from osg::Object are not handled. There is a Function Code: WriteResult writeObject( const osg::Object object, std::ostream fout, const Options* options ) const but this function only tries to cast into image or node and fails otherwise. It would be great to provide also serialization for osg:Objects. 2. documentation: I have a list of questions/ common mistakes. Should I modify the wikipage directly (login/permission required) or should i send you the list? Thank you!

Re: [osg-users] OpenSceneGraph and MultiThreading
Hi,
I searched the forum and was enspired by the following Topic:
http://www.mail-archive.com/osg-us...@openscenegraph.net/msg08183.html
I tried to create separate thread which will run from main function and run
LoadNodefile.
Code:
class MyThread : public OpenThreads::Thread
{
public:
MyThread(osg::Node* node) : _done(false),_node(node) { /* ... */ }
virtual ~MyThread() { /* ... */ }
virtual void run()
{
_node = osgDB::readNodeFile(cow.osg);
}
void stopWorking()
{
_done = true;
join();
}
protected:
bool _done;
osg::Node* _node;
};
int main()
{
osg::Node* node = NULL;
osg::Group* root = new osg::Group();
MyThread* myThread = new MyThread(node);
myThread-start();
root-addChild(node);
osgViewer::Viewer viewer;
root-addChild(node);
viewer.setSceneData( root );
viewer.addEventHandler(new osgViewer::ThreadingHandler);
while( !viewer.done() )
{
..
}
}
The value of node is null. I'm a newbie in Threading Programming, but I need to
find a way to work it out.
could anybody help?
Thank you!
Cheers,
Danny

Re: [osg-users] OpenSceneGraph and MultiThreading
Sorry, sent too early. Anyway, OSG has a potential solution to this - ref ptrs. If you pass and hold ref ptrs, then you will have two objects pointing to the same thing. Specifically, you would pass a pointer to your ref ptr. Having said that, I'm new to OSG - there's probably a better way. Please also consider thread safety - what would happen if your main thread tries to access the node while it's being created? What are you trying to do?

[osg-users] Two rotations on an object?
So i am learning to use OSG and am currently learning the basics and am currently creating little scenes to help me understand how it all works and such. I am trying to create a scene of a planetary system, using textures, lighting and primitives and am currently stuck with a problem that I cant quite work out, How to apply to rotations to a sphere. As it is a planet that I am trying to model it will rotate around its own axis and also rotate around a central sun. Below is what i use to get the planet to rotate around its own axis: Code: MatrixTransform *moon_Rotate = new MatrixTransform; moon_Rotate-addChild( geode_moon); moon_Rotate-setUpdateCallback( new AnimationPathCallback(osg::Vec3(0, 0, 0), osg::Z_AXIS, inDegrees(25.0f)) ); This works successfully, but how would I then add a second rotation to make it rotate around another sphere that I have created? Thanks for any input. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=24150#24150 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Two rotations on an object?
Hi, you could to it as a chain of PAT Notes 1. rotate to the desired angle of the planet around sun 2. translate the planet to add you desired radius 3. Rotate the plane to rotate it around it own axis.

Re: [osg-users] External threads and osgViewer
Robert, all, I've got it running by replacing the 'ReentrantMutex s_contextIDMapMutex' with a normal Mutex in osg/GraphicsContext.cpp:246. I'll send you the whole file on osg-submissions in a minute. I'll do some more testing, and probably create an OpenThreads::createForCurrentThread() if I hit more issues. Somebody suggested using SceneView in an offline email to me, but I'm not sure if this is a good approach since it is marked deprecated. Any opinions?
