[osg-users] PagedLOD preprocessing

Hi, advanced problem: Is there a chance to preprocess scene by OSG to use PagedLOD? The scene contains 3GB of textures (or any higher number). My idea was to make PagedLOD scene that would load high-resolution textures only for the most close scene parts to the camera. The problem is clear:

I tried by best and I found a way to solve thi problem. The idea is: First see the scene structure: SceneRoot Teapot01 Box01 Teapot01 and Box01 are the children of SceneRoot. When I select Teapot01, the osgManipulator::selection (I call it in my program Selection) set Teapot01 as one if its

[osg-users] Problem with makeCurrent implementation in osgViewer

In my previous posts [osg-users] Help - trying to get a wxWidgets implementation ofosgViewer::Viewer working! I described a problem with the viewer scene not being updated. I have now tracked this down to the implementation of makeCurrent in osgViewer. My application renders an osg scene in

Re: [osg-users] Problem with makeCurrent implementation in osgViewer

Hi Roger, If your app makes the context current in a different thread than osgViewer has for rendering to the same graphics context without osgViewer knowing about the fact that the context has been stolen from underneath it then it is not suprising you'll find problems. You'll need to either

[osg-users] Embedded Callbacks

I'm working on a system with several 100,000 separate items for rendering. So, they are being added to the scenegraph via PagedLOD's since each was originally created as a separate geometry file and later spatially partitioned at higher levels to reduce the number of actual distance evaluations.

Hi Robert, thanks for the quick reply. I've been playing around and it seems happy with using the same texture to render into. I've since used just a osgViewer::Viewer rather than the CompositeViewer, and it seems fairly happy. -J

Re: [osg-users] PagedLOD preprocessing

The problem is clear: OSG would probably freeze the computer during preprocessing when loading all the textures. In Inventor, it seemd simple: just to override the texture type and make the implementation not to load texture data. Any chance for solution in OSG? There every chance

[osg-users] How do PagedLOD children expire?

Hi Robert -- My understanding of the DatabasePager is that PagedLOD children that are not visible in the current view volume should eventually expire, which I assume means be unloaded from memory. OSG would then have to reload such children from disk if they ever came back within range. However, I

Re: [osg-users] How do PagedLOD children expire?

The DatabasePager has a lower limit on the number of expired PagedLODs before it starts removing expired ones; I believe the default is 100. So, unless 100+ PagedLODs are loaded, you won't see any removed due to expiring. I recall someone adding a function to the DatabasePager so you

Re: [osg-users] How do PagedLOD children expire?

Paul, PagedLODs are registered as inactive when their frame count gets out of synch with the overall viewer. Once they become inactive, their children are released. In other words, if each child has an identical bounding sphere, none of them will get freed until the lowest child is culled.
