[osg-users] OSG Python integration, take 2

I need to invoke OSG from Python code. I can't get osgswig working adequately in my environment, and I don't have time to chase the problems. So, time to write some C++. I have a Macintosh Leopard environment and a Windows XP environment. I can use either, but I prefer the Mac. I want t

Re: [osg-users] Windows wglShareLists and osg::GraphicsContext Sharing

Hello John, You can have a render context share lists with another context that has existing display lists. You just need to pass in the context with existing display lists as the first parameter to wglShareLists and the new context as the second parameter. OSG should get the sharing right au

[osg-users] Long-standing Particle System File loading IO performance trouble

This has been discussed on this list a number of times in the past, but I never saw any resolution. osgParticle systems cannot be cloned, so they can't be cached and cloned any time you want to use one. This means that each time a particle system is needed, it must either be read from disk ever

Re: [osg-users] MFC SDI Example

The OSG MFC example does not assert/unhandled exception for me. It does have the memory leaks that people have talked about. I'm not quite sure how to use the setUpViewerAsEmbeddedInWindow because the mfc example passes an dc to the camera whereas setUpViewerAsEmbeddedInWindow passes in a differe

Re: [osg-users] High resolution screencast

Ok forget about it it was a problem of -fPic flag in the compilation of some libraries. The next step is to make osg framerate constant in order to get smooth videos. If I undertood well what was said before this consists in rewriting the Mainloop of the viewer. I'll try this soon. Thanks once aga

[osg-users] Windows wglShareLists and osg::GraphicsContext Sharing

Guys, wglShareLists requires that the context which IS GOING TO SHARE has no display lists existing. NOTE: See the italicized hglrc2 at this link: http://msdn.microsoft.com/en-us/library/ms537565(VS.85).aspx This creates a massive problem if we start with one window and wish to create more (sha

Hi You can do this with a simple NodeVistor, that collect pointers in a array to yout Switch Nodes and Transfrom(DOF) nodes See something like http://www.vis-sim.com/osg/code/osgcode_bbox1.htm or http://www.vis-sim.com/osg/code/osgcode_color1.htm Add case for the swithc and transform nodes etc..

Hi Vincent, There are a number of different ways you can force an object(s) to render over the top of the rest of the scene. One way is the render a HUD scene after the main scene has rendered using a in viewer Camera or in scene Camera, other is set the RenderBin details on the a StateSet attach
