Re: [osg-users] [build] problem compiling osg 3.0.0 for Android
Hi, just a quick one... (I was not sure whether I should have posted it here or somewhere else. anyway...) I was testing the example application for OpenGL ES 2.0 and worked flawlessly using the Android 2.2 SDK. I tested on a Samsung Galaxy Tablet. I am testing now, using the Android 3.1 SDK for an ASUS Eee Pad Transformer. And I am out of luck... The result I get is the application starting (I can see the menu but the rest is black) and suddenly exiting a couple of seconds after. No error messages. Is this version of android (3.0 or 3.1) supported? Thank you!

[osg-users] Metadata: add new types?
Hi Robert, hi all, I'm moving our software to the current meta implementation. And clearly, adding new types handled by ValueObject is difficult: I may try adding META_ValueObject(SomeType, SomeTypeName), I won't be able to compile as Set/GetValueVisitor classes don't handle the new type. I may also try to create a MyTemplateValueObject which accept some MySet/MyGetValueVisitor (I did!), but there is plenty of problems, and cumbersome code to work around them. So I think I'm going to store my custom types directly as Objects, not as ValueObjects, manually handling the retreival of the values. However, if for exotic types there is no solution apart from modifying (again) the OSG's implementation, I ask if more common types may be added. Namely: - long - osg::Vec[n](f|d)Array classes - a DateTime class Thoughts? Do you think of any other type that could be added? For the DateTime class, I know there is no censensus on it and users may have choose different implementations. However this is quite common to require such a feature, and it may be useful to have a class in OSG for it... or at least a simple string that users may convert from/to their own type.

Re: [osg-users] Metadata: add new types?
Hi Suikender, It's meant that one would subclass from osg::Object rather than ValueObject for complex user types. The ValueObject type is meant just for simple values not composite/array values. Extended the OSG serializer classes is quite straight forward so I wouldn't worry about this aspect - once you wrapped a couple of classes it becomes pretty natural. The osguserdata example illustrates this in action. Robert. On Thu, Jul 28, 2011 at 11:16 AM, suky0...@free.fr wrote: Hi Robert, hi all, I'm moving our software to the current meta implementation.

[osg-users] Using existing OpenGL texture with OSG
Hello I have several SVG images which I want to use as textures in my application which uses both Qt and OpenSceneGraph. I want to do it using QSvgRenderer on QGLFramebufferObject. It allows to render SVG image directly on FBO and then use rendered image as texture like this: QGLFramebufferObject * fbo = new QGLFramebufferObject(width, height); QSvgRenderer renderer(QString(texture.svg)); QPainter painter(fbo); renderer.render(painter); After that I can use fbo-texture() to get OpenGL texture id and everything works perfectly in a simple test project (Qt + raw OpenGL). However I can't find any way to use this texture id with existing OSG classes. I've googled for the ability to use existing OpenGL textures with OSG and looked breifly through the code of the osg::Texture and osg::Texture2D and it looks like I have to create a class derived from the osg::Texture which will wrap external texture. Is it the right way? Are there any good articles how to create your own texture class?

I'm trying to think of a way to preload all of my textures into VRAM so that I don't get a frame rate stutter the first time one object or another comes into view.

[osg-users] Curious error on exit under Kubuntu 11.04
Hi All, Since I moved to Kubuntu 11.04 I've been getting a Inconsistency detected by ld.so: dl-close.c: 737: _dl_close: Assertion `map-l_init_called' failed! on exit from OSG apps runh from the console, it doesn't happen for all app/models, but even the same app can see the problem with certainly models, but not others. Looking on the web there seems to plenty of other applications with the same error since moving to Kubuntu/Ubuntu 11.04. I haven't really seen any good leads - the best I can guess from what I've seen with online discussion and my own tests is that it looks might to be something todo with libc, I don't wonder if it also might be related to dynamic loading of plugins.

Re: [osg-users] Moving skinned mesh by manually transforming the bones.
George Bekos writes: Hello OSGers! The last days I am playing with osgAnimation in order to implement something. I managed to make something work like I want it to but I don't know if this is the right approach or not. I will describe my problem and then I will describe my solution. I would be more than grateful if you could give my suggestions,advices,tips etc. Problem: I have a skinned (it has a skeleton, it is based on bones) hand model in a DAE file. The model does not contain any keyframes or animation. I want to import this hand into my OSG application and be able to move the fingers independently using the k/b. The movement of the fingers is simple: only rotation around an axis. (have your palm wide open and try to make a fist, each finger rotates around one axis that passes through the joint). Solution: * I load the model normally. * I get a pointer to a bone(using an osg::NodeVisitor). * I get osgAnimation::UpdateBone callback for that bone * I get get the osgAnimation::StackedTransform from that osgAnimation::UpdateBone * I push_back() a new osgAnimation::StackedRotateAxisElement (I also store the pointer somewhere else) to the osgAnimation::StackedTransform * Then I pass (using the constructor) the previous stored osgAnimation::StackedRotateAxisTransform pointer to a custom EventHandler that inherits from osgGA::GUIEventHandler and I add it (the handler) to the osgViewer (using addEventhandler()). * Then inside the handler() function of my custom even handler I check for key presses and then I modify the angle of the osgAnimation::StackedRotateAxisTransform. All the above seem to work fine, but I don't know if this is the right way to solve this kind of problem. I would appreciate any comments/suggestions/ideas/tips. Thank you very much for your time! Hi George, if you are directly moving a bone, you could bypass all the transformation system and just replace its update callback with one of yours that should compute the bone position in skeleton space.

If you want to inject fake events into the system, the WindowManager

bool MyClass::mouseReleased(

const osgWidget::WindowManager* wm

Would this work? I could still be misunderstanding something, or making
