[osg-users] [vpb] Creating .osga File
We have an existing terrain database consisting of 1x1 degree square .osga files. The database was created when osgdem still supported the -a option to compile everything into an archive file. We are upgrading our application to run on OSG 2.8.2 and I would like to rebuild the terrain database with the newer version of VPB and the corresponding OSG. Since I cannot create the .osga files with osgdem, I had tried to create the archive later with osgarchive. However, I can only load the new .osga file properly, with osgviewer, if the output directory containing the .ive files still exists and has not been renamed. If the directory has been removed, osgviewer will only display the master .ive file and does not seem to find the rest of the archived .ives. Is there a workaround to this problem, or some other way to archive the .ives into an .osga file?

[osg-users] OSG Viewer and JOGL
We currently have an application that is built around the OSG Viewer using a glut window. We are interesting in adding a considerable GUI interface to the application and we would prefer to use JAVA to implement the GUI. So basically I am trying to find a way, probably using JOGL, to create the GUI and graphics window on the JAVA side and perform all of the drawing on the C++/OSG side. I think I should be able to create a glContext on the JAVA size, with JOGL, and when making a call to C++ with JNI have access to the same context as long as it is done within the same thread. Unfortunately, I have not figured out how to assign the JAVA created glContex, retrieved with a call to wglGetCurrentContext, to the OSG Viewer/Camera. I know that osgvp has created a JAVA/JOGL/JNI interface to OSG but it looks like a lot of effort went into creating the JNI interface and making calls into OSG. I would really like to reduce the JNI to little more than init, display, keyboard, and mouse functions. Any help is appreciated.

Re: [osg-users] Overlaying Shapefiles onto Terrain
I played around with the osgsimulation example, and I think I may have misunderstood exactly what function the OverlayNode class performs. Using my shapefiles and one of our existing terrain files (build with VPB) I could never get the shapefile overlayed onto the terrain. If the shapefile was provided as the root object then it would be displayed as a filled polygon, otherwise only the terrain would be displayed. Basically I am trying to get a result exactly like the first example in this post: http://forum.openscenegraph.org/viewtopic.php?t=3309 The lat/lon coordinates are stored in a shapefile, but if it has to be pulled out and handled as individual points, that is not a problem. Thanks for any help. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=18542#18542 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Overlaying Shapefiles onto Terrain
I am trying to find a way to overlay some boundary lines defined in a shapefile across an existing terrain. I would like to support the ability to load shapefiles at runtime instead of generating a terrain file with the boundary lines with something like osgGIS. I have looked at the osgSimulation example and used that as a template to load the shapfile, but the lines defined in the shapefile are never displayed. Do I need to setup some attributes/states to properly draw the lines from the shapefiles?
