Re: [osg-users] Height Above Terrain for PagedLOD node converted from Proxy node
Hi, Is there any chance of querying the height of this terrain with OSG 1.2? OSG 1.2 doesn't have this osgSim::HeightAboveTerrain class.

[osg-users] Paging Openflight
Hi, I read some very interesting posts by Robert and Brian Hill on paging an openflight database. Robert says, 'The OSG natively supports database paging, and its automatically set up in osgViewer::Viewer/CompositeViewer when your scene contains osg::PagedLOD nodes - it's PagedLOD nodes that provide the information about the what to page in. The OpenFlight loaders doesn't know about paging itself, the format itself doesn't support as far as I'm aware. If you wish to use it forpaging then you'll need to take the database and convert to an OSG native format and insert PagedLOD nodes where appropriate.'How do I 'take the database and convert to an OSG native format and insert PagedLOD'? I actually managed to download ConvertPagedLOD.cpp from another post by Brian R Hill. Do I compile it in OSG environment, and then try to 'convert the osg::ProxyNodes to osg::PagedLODs'? How do I set the osg::PagedLODs center and radius?

[osg-users] Maximum database size without paging
Hi, I'm in the midst of converting a very large database of openflight files and textures into ive to be loaded in osgviewer. It seems that when my ive files are close to 1 Gb of size, my osgconv will crash from a windows error. When I break my flt files into a few ive files and load them with osgviewer, the same thing happen. I'm using osg 1.2, but I guess 2.4 will have the same problem. 1) Is there a maximum size (eg ive) that can be loaded into osg? Could the limit be on my graphics card memory or system RAM?2) Is there advantage to have 1 big ive, or a few smaller ive files?3) Is the limit more on textures size, or number of triangles?

[osg-users] TerraPage tile having own origin
Hi, I'm building a large visual database using Terra Page and running on OSG. I read that from Terra Vista help that Terra Vista allows the TXP database to have an origin for each tile instead of the whole gaming area. It states that This setting requires an extra offset for the runtime. Anyone knows how do we load such a database in OSG? I may need such a DB because my current XYZ is causing a lot of jittering from terrain to models and lights. Below is an extract from Terra Vista Help. Use this field to tell Terra Vista whether the coordinates in your output TXP database are offset with respect to the origin of the Gaming Area, or with respect to each tile. This could, for example, help if your coordinates were getting too large. Your choices here are: Origin. When set to Origin each tile will be relative to the origin of the database. This is the default setting. Tile. If set to Tile, each TerraPage tile will be relative to its own origin. This setting requires an extra offset for the runtime. The advantage of using Tile, is that there is more numerical accuracy for larger databases.

[osg-users] OSG with TerraPage. Buildings and lights flickering
Hi I have a large area TerraPage visual database loaded in OSG. When my 3D building models and light points (flt or ive) are planted close to the origin, everything works well. But when they are planted at somewhere far away, everything starts shaking and flickering, even at distances of less than 1km viewpoint. My X Y is only 5 digits. I've tried creating a matrix for my models and lights, creating external files etc. None of them works. I have to significantly lift models above the ground (eg 1m-20m) to have any positive results. I've heard that setting footprint and cutting up the terrain for my buildings, the problem will be resolved. But what about the lights flickering? Can anyone help? Is lifting my stuff above the ground the only way to solve this problem? 777 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] LOD problems using OSG with TerraPage
Hi, I'm using OSG viewer to see a txp terrain generated by Terra Vista. I have 10m and 1m imagery, with multiple LODs. I noticed that when I'm doing low level flying using OSG viewer, my most detailed LOD sometimes switches to the 2nd LOD. I'm flying just above the terrain, so it is quite impossible that the 2nd distances switched in. I've tried 3 LOD (10m) with high resolution insets (1m), 3 LOD (10m) with 6 LOD AOI (1m), and I noticed the problem pops most of the time when I generate the database. I've tried shifting the 2nd LOD to 50,000m to avoid the problem, but it still appears. Please help. 777 -Original Message- ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
