Re: [osg-users] 3D Frame Packing with OSG
Hi, I've found a solution to using the Sony HMZT1 with OSG and a Quadro FX 3800. It basically comes down to setting the following as per the Quad Buffered 3D Stereo instructions in C:\NVIDIA\DisplayDriver\driver version\your OS\International\NV3DVision\nvst3.chm which say: To enable quad-buffered professional stereo: From the NVIDIA Control Panel navigation tree pane, under 3D Settings, select Manage 3D Settings to open the associated page. Click the Global Settings tab. From the Settings box, click Stereo-Display mode and then select the appropriate option, depending on your stereo hardware. From the Settings box, click Stereo-Enable and then select On. Click Apply. From the NVIDIA Control Panel navigation tree pane, under Stereoscopic 3D, select Set up stereoscopic 3D to open the associated page. Make sure the Enable stereoscopic 3D check box is cleared, then click Apply. Sterescopic diplay type: should indicate Quadro professional stereo. It may be necessary to make the HMZT1 the primary display. Then use: Code: osg::GraphicsContext::WindowingSystemInterface* wsi = osg::GraphicsContext::getWindowingSystemInterface(); wsi-setScreenResolution(osg::GraphicsContext::ScreenIdentifier(screenNum), 1280, 720); or similar to setup the correct resolution. Try testing with the osgViewer using the QUAD_BUFFER command line option and cow.osg and... ...Hello 3D Daisy! Now on to integrating with our actual software. I would be curious if anyone figures out a way to make the HMZ T1 work with GeForce cards and OSG as my laptop doesn't have a Quadro.

[osg-users] 3D Frame Packing with OSG
Hi, I am trying to get OSG to output in 720p 3D frame packed format. My understanding is that this requires a screen resolution of 1280x1470 ( 2x(1280x720) + 30 buffer) but I must be missing something as the Sony HMD I am sending the output to is not recognizing it as a 3D format although it is displaying a down-sampled 1280x1420 desktop. I have been using the OSGViewer with command line arguments to specify a stereo mode of vertical split and am setting the screen resolution with: Code: osg::GraphicsContext::WindowingSystemInterface* wsi = osg::GraphicsContext::getWindowingSystemInterface(); wsi-setScreenResolution(osg::GraphicsContext::ScreenIdentifier(screenNum), 1280, 1470); If anyone has some experience with this I would be grateful for some pointers. Thank you!

Re: [osg-users] 3D Frame Packing with OSG
Jason, Thanks for the response. That link is helpful and i have done some research on the anatomy of modelines but no success yet. I am running my code on windows and while we occasionally build for Linux I'm hoping I don't NEED to go that route to crack this problem. It appears that my graphics card (qaudro something or other, not in front of it right now) can output 1280x1470 as I can see a desktop with that resolution in the HMD when testing it as a custom resolution. The osg viewer is launching without complaint at that resolution as well. Unfortuntely the HMDis not recognizing it as a 3D source. I will try your suggestion of forcing the black band between viewports. I wonder if the HMZT1 processing box is actually looking for black pixels in the middle of the source when it is determining if it should consider it a 3D format? I am having trouble finding this type of information for both the format and the device itself.

Re: [osg-users] OSG 2.9.9 - Problem building osgSim
Hi, For now I think the best thing is to compile OSG with the standard GL.h and only use the Qt version when absolutely necessary for our project specific work. Thank you!

Re: [osg-users] OSG 2.9.9 compile issues on Mac with Qt 4.6.3, other Qt issues
Hi JS, Can you confirm that the 2 examples you mention in your post made it into the 2.9.9 developer release? Thank you!

Re: [osg-users] OSG 2.9.9 compile issues on Mac with Qt 4.6.3, other Qt issues
Hi, I was referring to the osgViewerQt* examples - though I can see that is not clear in my original post! Thank you for the clarification. I have built all the QT examples in 2.9.9 at this point and they seem to be working great.

[osg-users] OSG 2.9.9 - Problem building osgSim
Hi, When building 2.9.9 the following warnings/errors are generated: 1SphereSegment.cpp 1.\SphereSegment.cpp(1368) : warning C4091: '' : ignored on left of 'double' when no variable is declared 1.\SphereSegment.cpp(1368) : error C2143: syntax error : missing ';' before 'constant' 1.\SphereSegment.cpp(1368) : error C2106: '=' : left operand must be l-value Build environment is Windows 7, VS2008 SP1, 64bit release with QT. Does the variable rad2 in line 1368 of SphereSegment.cpp redefine a macro or typedef? Renaming this variable eliminates the compile error. Thank you!

Re: [osg-users] OSG 2.9.9 - Problem building osgSim
Hi, So this issue (and many others) arises from the GL.h file that QT installs in place of the default windows version. Reverting to the vanilla GL.h file fixes it. Does anyone understand why QT does this and are there any tips for making QT play nice with OSG? Thank you!
