Re: [osg-users] Problems with setFinalDrawCallback and stereo rendering

Hi  Robert.

Thanks for your explanation.

I see that the camera-view-framestamp-framenumber updates every second time 
the callback is called, so I will try to use this to figure out witch frames I 
can skip and which frames to capture. 


Cheers,
Dag Magne

[osg-users] Problems with setFinalDrawCallback and stereo rendering

[Dag Magne Ulvang]

Hi,

I'm capturing screenshots to disk using FinalDrawCallback in order to make 
videos.

I am using the osgviewer in split horizontal stereo mode on a nvidia quadro 
graphics card (with support for quad buffer stereo, but I guess this s not 
needed in spit screen stereo) , but in the captured images the resulting left 
and right images are not in synch (in the attached image this is visible on the 
time in the upper right corner). Especially the right image is jumping while 
the left image is rendered as expected. 

Can anyone explain this behaviour, and maybe give a suggestion on how to force 
the images into synch?

Thank you!

Cheers,
Dag Magne
