Re: [osg-users] OSG and vsync (UNCLASSIFIED)

Hi Bob, The 2 frame latency thing didn't smell right to me either, having been used SGI machines extensively in the past. However after doing various closed loop latency tests, I'm convinced that the latency of modern Nvidia cards is higher than I would have expected. The 2 frame latency when

Re: [osg-users] Render to 3D image...

Hi guys ! The solution I suggested to myself, actually works ! So, if someone needs to render to a 3D image one day, one available option is to attach slices of the target images as mentioned below. To get those slices I used some code like (where z is the slice to render to) *osg::Image*

Hey, thanks for the info Frederic! Actually, the atmospheric scattering effect you're pointing me at is what I've been trying to integrate into OSG for a few days now and the reason why I ask those questions :-) So I already know the content of the main.cpp and copyInscatter1 program quite well.

Re: [osg-users] Render to 3D image...

Well, Fred, if this is rendered within OSG then I guess that's exactly what I want to achieve with respect to the atmosphere :-) No chance to get any source sample for the texture precomputation stage I guess ??? :-) By the way, there is another major issue I would like to submit to the OSG

Hi Fred, I had tried 0 and 1 before but that gave me the exact same behavior. So in your application you have a different osgviewer window that displays in each screen the moment your program starts running ? I don't know if there is something wrong in the way I'm setting up my graphics

Hello Sanat, From the code you posted, you're creating 3 graphics contexts using the same traits for all 3. This will obviously put all 3 on the same screen. traits-displayNum and screenNum need to be set to the screen you want, a different one for each context. Hope this helps, J-S --
