[osg-users] osgDB FilePathList std::deque vs std::set

Re: [osg-users] Updating a portion of a VBO?
Hi Glenn, Right now the OSG just supports updating an entire VBO when used via the osg::Array class. You could implement your own subrange copying by getting the VBO handle yourself and then manually doing the copying that you need to do. The other alternative would be to look at how one might conveniently add support for uploading sub ranges. So far I've avoiding tackling this as the API for is potentially quite cumbersome. Robert.

Re: [osg-users] Overlay nodes on complex polygons
HI Arthur,
Projective textures such as done in the OverlayNode knows nothing
about depth so can't do what you require as is. The best you could do
is just decide yourself what whole objects have the texturing on them
by enabling/disable the texture modes for them, or excluding them from
the OverlayNode subgraph.
From the sound of it what you are after is very specific to your needs
and you'll need to pursue another technique, this might involve
projective texturing, but since you have a very specific usage you'll
need some quite custom.

You can't expect others to dive into huge amounts of code and know

As for DYNAMIC - this is required when you have dynamic Geometry/Text

Maybe I missing something in what you're asking If you add and remove more data then you simply remove all the child of the group or PAT and then add the new nodes you want If you mean you want to actually scale everything under a PAT or group then you can set the scaling on a PAT, on a group you will have to insert a matrix above the Groups to scale the group and its children BTW I don't think it's all in the title you offer too little information I would suggest expanding on what you mean in this case because what you ask could be interpreted in many ways Gordon Tomlinson Product Manager 3d Technology Project Wyvern Overwatch(r) An Operating Unit of Textron Systems -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Ku Krapox Sent: Tuesday, May 11, 2010 9:08 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Shrink/Enlarge whole osg::Groups ?

It looks like number of vertices is growing in each frame. We have tried to rebuild, reinstall osg, clean caches etc, but results are still the same.

Re: [osg-users] fbx writer texture support
I found the cause of missing textures. If you have a Stateset with textures applied to a Geometry node, it generates an fbx file with textures. If the Stateset instead is applied to the Geode parent of the Geometry, you get no texture. Unless Sukender has some suggestions on how to tackle this, I'll try to figure out whats going on in WriterNodeVisitor::apply(osg::Geode node).

[osg-users] Object picking in Horizontal_Split Stereo
Hi everyone, I' ve been trying to get object picking using the mouse (and later using a 3D mouse equivalent) in a HORIZONTAL_SPLIT stereo mode setting. My initial code was using the osgPick methods ...resulting as you might imagine to completely wrong x coordinates and it took me ages to figure out it was the stereo projection messing it up. The problem is that apart from the viewport being double the horizontal size of what is actual rendered for each eye, there is also the eye separation offset that complicates things even more. I am considering 2 options to fix this: 1. Create a new mono view that is half the horizontal size of the stereo view and use it to pick the object. However this view should be renderless. How can this be done? 2. Take the double viewport width and the half eye (eye separation is total distance between eyes) separation values into account and rewrite the matrix transformations from screen to world coords. Has anyone done something like this before that can point me to the right direction? Code snippets will be most welcome :) ... Thank you!

Re: [osg-users] Object picking in Horizontal_Split Stereo
Hi Thanos, I haven't tried it myself yet, but you could try creating the split screen stereo up in osgViewer as two slave cameras, rather than let the lower level SceneView implement the stereo. Doing the work in osgViewer will allow the viewer to know about the viewports and hopefully do the appropriate reprojection. Robert.

[osg-users] Optimize and setDataVariance(osg::Object::DYNAMIC)
I've seen many posts on the forum (as well as the QSG) that say that setting 'setDataVariance(osg::Object::DYNAMIC)' will stop nodes from being optimized out of the graph. I've had several instances where this doesn't seem to be true. Most recently, I have an osgFX::BumpMapping node that is definitely being optimized out. I've set the data variance to dynamic for the node, all of its children and statesets and it still disappears. Remove the node, and everything else is fine. Turn off Optimize and everything is fine as well. Is there any absolute way to be sure that nodes will not be optimized out of the graph?

Curious, if yo are running in separate threads then I wouldn't have expected the Qt threads rendering to hold back the viewer as it shouldn't be blocking. Is the CPU just heavily contended? How many CPU cores do you have? This can probably be improved by using QGLWidget for rendering the widgets to texture. I am not that deep into the whole topic yet. Mixing render to FBO/texture rather than just direct GL will probably introduce similar problems to the straight GL route. One problem with using Qt for GL is that it couples the OSG with Qt in a way that forces the OSG to run single threaded as Qt itself is single threaded.
