[osg-users] Depth, CULL, renderBin : what and when ?

Hi, I need some explanations about the ways OSG allow to modify the render. I am working on a function, to apply to a node, to set it always rendered over the other nodes. In other words, If I apply this on an osgText, I would be able to read the text whatever my camera position can be (of

Re: [osg-users] Depth, CULL, renderBin : what and when ?

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

Re: [osg-users] MFC SDI Example

The MDI mfc version has the same problems last time I tried it. Try calling setUpViewerAsEmbeddedInWindow on your viewer. If you problems go away you're hitting threading issues. 2009/1/8 Brad Huber br...@procerusuav.com: Umit, Thanks. The SDI application that I have created so far is very

Re: [osg-users] Image writers without compression support still try

Hi Roland, This sounds like a bug in the various image plugins don't detecting a pixel format that don't support. The file name extension for compressed files really should be .dds, but this isn't under the control plugins as you could load an .rgb file then compress the image at runtime, but

Re: [osg-users] Depth, CULL, renderBin : what and when ?

Hi, Thanks for your explanations. If anyone can explain me the Depth class and the binName string , I would be very grateful. For now, I've tried this : *void setNodeAlwaysRendered(osg::Node* n) { if(!n) return; osg::ref_ptrosg::StateSet state = n-getOrCreateStateSet(); //no

Re: [osg-users] Depth, CULL, renderBin : what and when ?

Re, Some correction : But nothing changed... I apply it on a PAT, and on a geode ... but the node it still culled by the other one... I use HUDs in the scene, but the scene graph is not attached to them... so I don't think it can explain that. Correction : Sorry I was wrong, it works on a

[osg-users] finding switch and dof nodes in a 3D model without name

Hi all, I have a application that load some 3D models in .flt format. This models include both switches and Dof and I like to enable it. To do so i have done a research in OpenSceneGraph documentation and I have found the tutorials regarding the argument (in particular [1]). It works well but I

Re: [osg-users] finding switch and dof nodes in a 3D model without name

Hi Francesco, You just need to write a NodeVisitor that traverses through the scene and detects the osg::Switch and osgSim::DOFTransform. The NodeVisitor has an apply(osg::Switch) method, but not a DOFTransform one so you'll need to implement and apply(osg::Transform) and then dynamic_cast this

Re: [osg-users] finding switch and dof nodes in a 3D model without name

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

[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

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

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

[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

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
