Re: [osg-users] Error in the new version OSG
Hi Maxim, I haven't seen any threading issues with svn/trunk, testing with Kubuntu 10.10 64bit, and there aren't any recent changes that are likely to affect threading behaviour under Linux. I would suspect a build issue, runtime linkage issue. Could you try a clean build and double check that you don't have older plugins being loaded due to hardwired paths to plugins. glxinfo on my machine returns: OpenGL renderer string: GeForce GTX 260/PCI/SSE2 OpenGL version string: 3.3.0 NVIDIA 260.19.06 Which isn't quite a recent as your driver, so I guess that might be another variable. Beyond this I can't really add too much other than to suggest a debug build and looking at the track trace at crash. Robert.

Re: [osg-users] Flush event stack
Thanks for reply, I have some another question. Using osgUtil::PolytopeIntersector we get the x, y, and z coordinates at current mouse position. Can I do opposite of it, means if I have x, y and z coordinate then, can I calculate the screen coordinate. Actually I have to find points around a given coordinate. Or is there another method to find the nearest points around a given point (range is also given) Thank you!

[osg-users] stats issue with svn
Hi all, Not sure if its just me: But on Windows7 64bit,VS 2008 build, latest SVN, when I run osgviewer cow.osg and enable stats using the s key, my draw rate shows up as 15-16(draw thread per a context). Cycling through threading modes using the 'm' key gets rid of the draw rate problem and it drops to a mere 0.10. Anyone else?

If you want to create and chain RenderStages then using an osg::Camera in the scene graph is often one of the best ways to do this, and use the Camera::setRenderOrder(..) to control the order. You can also use a custom cull traversal callback to create RenderStage/RenderBin and assign these to the rendering backend, but this does require a greater knowledge of the internals of the rendering backend.

I have several more post-processing stages to follow, so I'm convinced that's the way to go for me to have full control over the pipeline.

It's also very inconsistent. Sometimes you'll start osgviewer and it's fine already, sometimes it will be in this weird state. Sometimes 'm' a few times will bring it back to normal, sometimes not. (anyways that's my experience) If you have a lot of experience in debugging threading issues, you might be able to have a look, as it's probably caused by timing between threads or something like that.

[osg-users] iOS: integration with not-OpenGL apps
Hi, I'm trying to find a way to integrate OSG into a generic app for iOS, but I'm facing some problems. Maybe I'm missing something, but as far as I've understood, it looks like that, in order to use OSG on iOS, I must always use the UIWindow and the corresponding UIView/UIViewController objects created by means of GraphicsWindowIOS::WindowData...but in this way I find difficult to later manage those UIView and UIViewController objects especially if I need to integrate them in a dynamic view hierarchy. What I'd like to do is to create a UIView-derived class that encapsulates everything required to use OSG to draw in just that view, then I'd like to manage that view by my own UIViewController (not related to OSG). Is there a way to do this with what is already available in OSG (2.9.13)? If not, can anyone suggest what (beyond creating a context and all OpenGLES related stuff) the UIView-derived class should do from the OSG point of view? Thanks.

[osg-users] Cannot get texture map from loaded .flt file

I have tried to get the texture map from the loaded .flt file but it returned
null.
I have looked up the thread here
Code:
osg::Group* Ground = dynamic_castosg::Group*
(osgDB::readNodeFile(C:/Program/Multigen-Paradigm/creator_3_2/tutorials/DesktopTutor/Models/arena.flt));
I use a node visitor to find all geodes in the scenegraph Ground and the
apply function looks like this:
for (unsigned int i=0; icurrentGeode.getNumDrawables(); ++i)
{
osg::StateSet* StateSet =
(currentGeode.getDrawable(i))-getStateSet();
osg::Texture* Texture = dynamic_castosg::Texture*
(StateSet-getTextureAttribute(0, osg::StateAttribute::TEXTURE));
--- modify the texture ---
}
l
It said use the option
preserveFace
can get the texture. But I still cannot get any info from the model.
Is there any one can get texture from .flt without any problem?
I have also attached the flt file and let others try to get the texture.
Thanks
Cheers,
ChiaYuan
