Hi Stefan, Could you be more specific about what you are talking about? I think none of OSG-User can understand your problem. So if you want a solution, firstly try to tell more understandable way. Regards. 2009/6/15 stefan nortd ste...@nortd.com Nice, I was just looking into using

[osg-users] Using the z Buffer

Hi folks, I am using the z-Buffer in osg 2.4 and have problems getting reasonable values. When the camera is about two meters away from any flat object surface, I'll get the value 0.995, and when the camera is about eight meters away i'll get 0.997 from the z buffer. I have also tried to

Re: [osg-users] zbuffer issue

Hi Christian, I really doubt you have a general z-buffer issue, but from the pictures is looks like you have problems with geometry that is overlapping that shouldn't be. Any chance that you are accidentally creating quads that overlap in your code? Robert. On Sun, Jun 14, 2009 at 11:06 PM,

Re: [osg-users] OSGSpotLight example on a GLSL material

HI Albino, I'm not quite sure where to start... your GLSL shader doesn't seem to have any reference whatsoever to projective texture coord setup in the vertex shader or application of the projective texture in the fragment shader. To me this suggests that you haven't yet learnt enough about the

Re: [osg-users] Using the z Buffer

Hi Roland, A couple of points. First up if the CompositeViewer is being run multi-theaded then the draw traversal may not be complete, and the values not copied yet to the osg::Image by the time your frame loop reaches your image data output line. In this context it probably will just mean

Thanks Robert. Do you think the problem exists, because of not clearing the z buffer at the beginning? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=13981#13981 ___ osg-users mailing list

Re: [osg-users] [build] Can't build libraries under windows

Hey Ümit, Thanks for your answer. It's actually not that complicated. jonim8or compiled osg for mingw and posted it online. Unfortunately the link above in the thread is down. I was just wondering if these mingw binaries can be made available again. I think people would find them useful

[osg-users] SVG plugin

Hi all, I saw in the osg 2.6 release log a svg plugin. But, it does not appear in the cmake config or in the compiled plugin and 3rd parties. So i can assume there are some external dependencies, or a special procedure to install it... but I did'nt found anything. So the first question is : how

Re: [osg-users] zbuffer issue

Hi, thanks for all the reply like colin noted, the render problem vanished as i stripped off the offsets which caused the large coordinates and work now with localized coordinates. if i ever need to display the real coordinates in an text-insert, i can re-add the stripped offset before display

[osg-users] Annotating large numbers of objects

Hi, I need to label or annotate large numbers of 3D locations with a short label like a number. Think possibly 100,000+ locations or nodes (for example, represented as small cubes). I naively used osg::Text to create labels and ended up consuming 100's of MB of memory. This seems like a case

Re: [osg-users] Annotating large numbers of objects

Hi Chris, Thanks for the suggestion - I am backed into a corner a bit by the need to support access via Windows RDC ( remote desktop connection) which works quite well for small/medium models but only supports basic OpenGL(1.1?) without shaders. Of course I can test for that and use an

[osg-users] should ViewerBase::_done be volatile?

Subject says it all: shouldn't the done flag be volatile? If it isn't, how can you be certain that the viewer thread will ever notice it has changed from false to true? Some context here: I call ViewerBase::run() in its own thread. To shut it down, I call viewerBase-setDone(true) from my main

Nevermind, I made it compile. It looks nice (see attached image) and is fast for a real time ocean simulation. But apparently it doesn't find the instaled resources, neither in the bin directory (instaled there by default) nor in the OSG data directory (where osgDB find things). Only finds them
