Re: [osg-users] Deos readNodeFile(OSGDB) support multithreading?

Hi robertosfield and hybr, Thanks a lot for the nice help. My develop environment is windows XP 32 bit with SP3. On 32 bit machines the code works well. When I run on Win - 7 Ultimate 64 bit then I am getting run time error some times. I dont have development environment on 64 bit machine.

Re: [osg-users] Screen Distance

HI Till, The DisplaySettings::ScreenDistance value is used as hint to set up of the eye offset (in world coordinates) to use when wants to scale the model so that the center is at the image plane, this is done with the trackball/terrain camera manipulator so that when you zoom in/out the stereo

Re: [osg-users] Rendering issues with `osgVolume::RayTracedTechnique`?

Hi Robert, It's likely to be a driver bug, or perhaps a sensitivity in the driver to the GLSL shaders that are used - sometimes some drivers can be more picky than others. We also thought about this possibility. Is it possible to obtain debug information about the way the card processes the

Re: [osg-users] Deos readNodeFile(OSGDB) support multithreading?

Hi Koduri, I think perhaps you should take a few steps back from the approach you are taking a learn a bit more about the basics of threading, performance profiling and optimization before you dive into implement threading to try and tackle what you perceive to be the way to solve problem. So

Re: [osg-users] Rendering issues with `osgVolume::RayTracedTechnique`?

Hi Robert, [...] If using the DEBUG notification doesn't provide any clues then only other tools you have left are 3rd party OpenGL debug tools. Unfortunately AMD have swallowed up glDEbugger so I you options are now a bit more limited. Perhaps others can suggest options. Another route

Re: [osg-users] Qt and OpenThreads

Thanks, Nico, very interesting info, I'll read that through. Was not my case, though: Can't believe how dumb my mistake actually was was: mixing release OSG libraries with debug Qt libraries. Never mix debug with release, thats what I've learned :) Thanks to all who wanted/tried to help.

Re: [osg-users] Deos readNodeFile(OSGDB) support multithreading?

Hi one reason for binary files to be huge is embedded media like textures, as they are stored as uncompressed data. you can use binary formats with external image files (pngs \ jpegs) in this case to cut down file size. you can use osgconv with various options to sort htis out, check osgconv

Re: [osg-users] adding tool tips to objects in a 3D scene

I've been asked to add some tool tips to objects in a 3D scene, and I wonder if there is anything existing in OSG that would facilitate an implementation. I figured it out myself - and I think I got that done with quite minimal effort. We're already integrating Qt and OpenSceneGraph by means

Dear list, we collected some debug output of the shaders in question under http://pastebin.com/L88sCxBn. Around line 247 of the paste, things seem to get interesting. I am not quite sure what to make of the ...is not supported entries. Is anyone able to help? Kind regards, Bastian

Hi, Sorry, please disregard my last message - I wasn't reading carefully. There are is supported and is not supported messages. The is not supported messages require a closer look. Christian ___ osg-users mailing list osg-users@lists.openscenegraph.org

Hi, Seems to be working if I disable some effects such as glare and some underwater effects (I did not look exactly which ones are causing the problem). Cheers, Janna -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=50198#50198
