Re: [osg-users] OSG Animation Tutorial

I don't know if they are tutorails about this, but animation can be done with OSG. To set your animation, you can use blender for example and then, export to osg. Then, use osgCal to perform animation and skinning. Eric -- Read this topic online here: http://forum.openscenegraph

Re: [osg-users] OSG and QT problem

Hi, I experiment this. I used an already displayed scene in another viewer. (I think you do not reload your nodes). So, they are a marker in the osg::Texture which indicates to unref the image after apply. I thinks it a save memory trick. But in our case, the image does not exist anymore w

[osg-users] Qt4, OSG and HUD

Hi all, Since Qt 4.4, we are able to mix OpenGL and Qt in a way which provides more possibility than the osgViewerQT do by using QGraphics framework, especially for HUD display. I joint the example I write to do this. The main function loads a model a display into my QGraphicsScene inherit

Re: [osg-users] Rendering the scene multiple timeswith differentshaders.

I don't know how you perform your multi-pass rendering. But as far I understand the nodeMask, a node is traversed if the logical AND operator between the visitor mask and the node mask is not null. So, if you use two cameras, the first can have a mask to 0x1 to render the subgraph Node_1 and the

Re: [osg-users] Rendering the scene multiple times with differentshaders.

I think use osg::Switch is right way to do. You can set a StateSet to any Node, then (correct me if I'm wrong) all children will inherit the stateset. So, I think about a graph like this: Root | | Switch ___|__ |

Re: [osg-users] Object position on screen coordinates

Hi, To display a node on top of the other, I think you can set off the depth buffer test and put it into a render bin up all the others (> 10, since it is the transparent bin, if I remember) to draw them at the end. It's all done via StateSet, you should find them easily. Eric Z. -Messag

Re: [osg-users] OpenSceneGraph 2.19 osgViewer

I'm porting my application from 1.2 to 2.x too and meet the same problem. To render an empty scene, I do a viewer->setSceneData(new osg::Node); In osgViewer the function frame() do all the work for you and, anyone can correct me if I'm wrong, you do not need to call any update() anymore b
