[osg-users] Scene.cpp deadlock

Hi, I found a deadlock in Scene.cpp. The problem exhibits itself when calling std::exit() instead of standard way of terminating of the application. The deadlock is seen on Windows only. On Linux, I get sigsegv or, at least, valgrind gives me info about using already freed memory. After the

Re: [osg-users] OpenSceneGraph performance drop between Qt 4.7 and 4.8

Hi Marco, I can not test it right now, but when Qt 4.8 will be made available with the new Ubuntu release in April, I will probably dig in the problem if I notice it on my application. John On Monday 12 of March 2012 11:10:51 Marco Fiocco wrote: I've even disabled the vsync but it does not

[osg-users] light position through uniform

Hi, I want to place a light into the scene without using fixed pipeline. Thus, I created uniforms to pass light parameters to shaders. These works fine except light position and light direction. I want to pass light position in eye coordinates. I expect, I have to multiply

Re: [osg-users] best format for paged database

Thanks Brad, osga is really what I was looking for. It can store everything and it contains index, so the only overhead on open is to read the index (and not the whole file as with some other formats). I am going to try it. John On Thursday 08 of December 2011 20:20:16 Christiansen, Brad

[osg-users] best format for paged database

Hi, what is the best file format for paged scene database? The database may be both - small and big (gigabytes) and it may or may not contain geospatial data. The special requirement is that it should be possible to store non-standard data like reflective color (not present in OpenGL), for

Re: [osg-users] Interest in new releases of 2.8.x?

There is one research group at our university waiting for any new official release. They ask me from time to time about it. However, they are not apparently reading mailing list too often as they are busy with their own things. I guess that number of people would welcome the new release

Re: [osg-users] Interest in new releases of 2.8.x?

Is there any feature they specifically want in a new release, or are they just wanting the 3.0 stable release? If I remember correctly, it was mostly related to CMake scripts. Probably those responsible for finding the libraries on the disk. These should not be difficult to include in

Re: [osg-users] saving camera view state

What about keeping your cameraManipulator using ref_ptr (instead of deleting and creating another one. By the way, your code deals with HOME position, not with current manipulator position. If you will be still lost, look at lexolight.sf.net sources. It uses two manipulators and you can swap

[osg-users] requestRedraw bug during ON_DEMAND rendering

Hi all, I am using osgViewer::Viewer in ON_DEMAND RunFrameScheme, e.g. there is no continual re-rendering and 100% CPU loading, but the scene is rendered only when really needed. Bug: The window is not repainted when obscured by another window and re-shown again. I was trying to fix the

Hi Vincent, void CameraManipulator::setHomePosition(const osg::Vec3d eye, const osg::Vec3d center, const osg::Vec3d up, bool autoComputeHomePosition=false) takes eye parameter as a position of the camera. Center is any position that camera is looking at, giving the orientation of the camera.

[osg-users] extension detection

Hi, I am currently puzzled by some code inside OSG to detect extensions. Example code: _isSomethingSupported = OSG_GLES2_FEATURES || OSG_GL3_FEATURES || isGLExtensionOrVersionSupported(contextID, GL_EXT_something, 2.1); Question 1: Why we are sometimes testing for version? e.g. 2.1?

Hi Holger, I would prefer to have an export to OptiX native format. And if there is none, to have a class that would take OSG scene graph as a data source, setups OptiX node graph and does OptiX rendering, returning final image. That would be a very cool class for anyone interested in

[osg-users] textures in osga

Hi, I want to put textures and geometry files to one archive file. I looked at osga plugin, but I am not sure if it can be used for such a purpose. If I read particular geometry file from osga, it may trigger loading of a texture that is used by the geometry (e.g. standard material texture).
