Re: [osg-users] Paged LOD for osg terrain

Hi Brett Osg paged lod is basically implemented as the name states, there are a pagedLod node in your model that will spawn a load of the nodes below it when it gets close enough to the camera and is inside the view frustum. I guess the technique is quite similar to a standard LOD node except

Hi John, I believe the problems you are seeing will probably not be related to the changes I've recently checked in w.r.t the texture pool. Have you had osgviewer and present3D working fine on this machine with these models/presentations before? What spec hardware (i.e. graphics card, CPU etc)

[osg-users] osgWidget event handling question

Hi osg-users, I would like to know if there is a way to handle an event by a widget like a push event and tell other GUIEventAdapter to not handle it ? My goal is to have a widget with some matrix manipulators, but when I click on the widget area I don't want the matrix manipulators to handle

Hi Alexandre, GUIEventHandlers are themselves responsible for deciding whether they want to handle an event that is already handled or not. In your can return true from your own handle() method or setting the handled flag on the event. Have a look at the ::handle(..) implementations in

Hi Robert, I agree that it has nothing to do with your recent changes. My suspicion is it has something to do with file i/o, or, if it's involved (?) - threading - and me having used a wrong version of something. What part of OSG/P3D handles the i/o? ( This is my home computer on which OSG

Hi Dimitrios and Jan, I have the same need. I was looking at the code and while the information is obtainable from the raw heightmap (there is even a convenient interpolation function for it), it is not exposed in the public API. I think you need to hack the osgOcean code and expose the
