Re: [osg-users] Multi screen & VSync & Linux & NVidia

Serge, as Robert says, TwinView is what you need. Here's the deal. On Nvidia non-Quadro cards on Linux, the only way to guarantee no tearing on one screen is: UBB flipping enabled, full screen OpenGL app, no obstructions, Vsync flag with that screen number - there's an environment variable.

Re: [osg-users] osgtexture1d example / osg::TexGenNode order

Hi Robert, yes, this is what I understand, I think. But that means the example relies on the fact that children added to a parent are ordered in the same way as they are added. So, root->addChild(texGenNode); root->addChild(loadedModel); should not work, or? Thank you! Cheers, Hartwig -

Hi Huiliang, so as far as I understand you want to have the output of the osgPPU's pipeline for further processing, right? If so, then take a look into video example. There the output of the osgPPU pipeline is used as texture over the quad. In this example last unit is UnitInOut in order to use

Hi Serge, Enable the unref image after apply in your case is a bit awkward as, as you have found, the mechanism assumes that all contexts will require the texture. Another way around the issue is to use the texture object pool to keep a cap on the memory usage on the driver and GPU side. Another
