Re: [osg-users] mygui integration (for Wang Rui)
Thanks Wang, actually I figured it out. I study the code and yes, I am seeing the Drawable calling the rendering method (doOneFrame()). However, the OpenGLRenderManager in it's override of begin() is calling glClear() so no matter I was doing mygui was keeping clearing the background even if there was no background widget, so I had to override all of these to make it work. Your suggestion can do the job but no blending of widgets with the OSG scene, since these glClear But, thanks a lot Cheers, Nick On Thu, Nov 12, 2015 at 1:55 AM, Wang Rui wrote: > Hi Trajce, > > This should be easy because MyGUI window is encapsulated in derived > osg::Drawable class and displayed in a HUD camera.

Re: [osg-users] mygui integration (for Wang Rui)
Hi Trajce, This should be easy because MyGUI window is encapsulated in derived osg::Drawable class and displayed in a HUD camera. You may simply set the camera ortho matrix to a different value like (0.0, 0.4, 0.0, 0.4) to have OSG scene as background.

Re: [osg-users] [build] using 3Ds Model in osgFX::BumpMapping and the Texture UV Coords for diffuse are not loaded
I never thought, that I can say this. But I resolved my problem. Thank you Scrawl for your tip using an own shader. I used the shaders from http://fabiensanglard.net/bumpMapping/index.php (Vertex shader + Fragment shader) and modified it in addition from http://forum.openscenegraph.org/viewtopic.php?p=38982#38982 and this works fine also with a TexMat :) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=65608#65608 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Robert, I removed the xrandr version check just for a try. Some old RedHat and CentOS distributions (at least 5.9) uses an xrandr version 1.1.1.

Re: [osg-users] xrandr version
Hi Gianni, I don't recall the decision making process w.r.t the xrandr 1.2 version check, it'll have been quite a few years back. My guess that was the minimum version that looked appropriate at the time. Just throwing away the version check is unlikely to be generally safe. It'd only be safe if we could confirm that all versions of xrandr in circulation supported the functionality that osgViewer's X11 code paths require. A better solution than just removing the check would be to find the earliest version of xrandr that supports the features we need. I'm curious, what system are you using for it to only have an old version of xrandr? Robert.

[osg-users] xrandr version
Hi, I'm trying to get the screen refresh rate from GraphicsWindowX11::getScreenSettings(...). Looking at the code I realized the point is the xrandr version. In fact supportsRandr() methods require xrandr version at least 1.2. But since I found the line: OSG_NOTICE << "You must build osgViewer with Xrandr 1.2 or higher for setScreenSettings support!" << std::endl; I suspect my xrandr 1.1.1 whould be enough to just read the sceen refresh rate (and it works fine indeed if remove the xrandr version check!). Moreover the supportsRandr() check is used just in two methods that simply read the screen settings while in setScreenSettings(...) it is not used at all. Now, in the actual code (I verified the OSG trunk), the xrand version check is really required?
