Re: [osg-users] Particles not working
I'm posting the solution to my problem should anyone encounter the same dumb problem. It appears I had left in my code a line that changed the root scene node every frame. I think the particles may be reinitialized when the root scene node is changed, so the particles never got beyond the first frame. I just changed to change the root scene node only if an actual change took place, and it works. It was on my todo list, but didn't think it would be relevant. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=30555#30555 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Particles not working
Hi, I'm trying to add some particle effects in my project. I took the spaceship model shipped with osg, when I load it in a viewer it works fine. When I load the same model in my project, the hull of the ship appears, but not the particle effect. I'm using SDL as a window, and my code is derived from the SDL viewer. Camera is moved manually, so there is no camera manipulator. There is also no event handler. I tried giving viewer::frame() the frametime, but that didn't fix it. My project is over 4000 lines of code, and I have no idea where the bug may lie, so excuse me for not posting the code. I'm just wondering if some of you could give me pointers as to what may be wrong, so I can find the relevant part myself. Thank you for any help you can provide with that little info. I'll gladly supply parts of the code that seem relevant, I just can't figure out what is. rewpparo -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=30491#30491 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] OSG + SDL
Geez thanks I feel ashamed now, that's exactly what I'm looking for. I got myself settled for some hacking and never thought it would be this simple. When you think about it it makes perfect sense.

[osg-users] OSG + SDL
Hi, I'm trying to use OSG to draw to a SDL window. I've found lots of information everywhere on this, but it all seems to use SceneView, which is said to be deprecated, and doesn't work when I try it. It's a shame because it's exactly what I needed to integrate nicely with my code. I heard there's another way to do this, using the osgViewer, but I never found a sensible piece of code that would explain me what to use and how it works. I would rather use my own code to do this rather than a library, as I need a good control over input and over the SDL event queue. The best would be a way to draw a scene to the current openGL context, using only opengl commands. What would be the correct way to do this ? Thank you for any information regarding this.
