[osg-users] Qt crashes on key press

Hello! I've a problem with Qt once again :) There is OSG scene, where I put some Qt controls, like in osgQtBrowser example, where Qt controls are getting rendered like OSG objects (I create camera for them and stuff). So, when I press any key on keyboard, Qt controls just jump somewhere around

[osg-users] Updated FFmpeg plugin

Hello! I have been making updates to the FFmpeg plugin that I believe would be useful for others using OpenSceneGraph. The updates mostly revolve around changing the plugin to use APIs from FFmpeg 0.11. Since the previously supported version of FFmpeg is at least two years old, is it important

Re: [osg-users] Shader reloading

Hi, Christian Can't help you with crash, but i think you can find this usefull: 1) noise functions for glsl not implemented in hardware\drivers of most vendors, so dont even bother to use them. 2) why do you ever need to recreate program and all that stuff, if all you need is to change randomUni

Re: [osg-users] Why to reset OSG settings every time while rendering in Android

Hi, I came to know that the "QCAR::Renderer::getInstance().drawVideoBackground()" statement clears the OpenGLES context. I think this is the reason to reset the OSG setting every time. I tried to restore the OpenGLES context as follows. Store the State object at initial time and restore it af
