Hi Robert -- I've encountered a small issue in developing my OpenFlight
export plugin, which is written as a separate plugin from the existing FLT
import plugin.
I have a small test app that performs the following steps:
1) Register an extension alias so that osgDB knows my export plugin support
Hi Every One!
I'm working on the 3D terrain visualization. I want to split the Terrain
Image into many tiles. And then build their LODs( like Quad tree ). Now I don't
konw how to fix the gap between adjacent tile( in the same and different LOD
level ).
I 'm long for your suggest.
Thanks!__

this little hack makes this approach work:

Hi,
i'm trying the second approach of having a FBO greater always. Is there an
easy way to set a FBO and copy only a portion of it back to memory? Using
FBO, an image to control the transfer to main memory and the requisite of
having image copy the pixels in a specified location (given pointer),

Sorry Jeremy. The atheist in me thinks you may not be a god. But please
forgive me anyway, I only build osg on windows.
(But I do run a real operating system on most of the other systems here :-)

Hi,
CameraNodes unlike SceneViews don't appear to have a getCullVisitor()
function, I'm guessing they're visited by the same CullVisitor as the
root SceneView that contains them. Without access to this "root
SceneView", is it possible to get access to the exact projection
matrix applied to

Thank you so much Jeremy.

Okay, just so you know this isn't anything you're doing wrong. The build
is broken in some way. I'll fix and make a post here and to submissions.
I'm getting the exact same error as you.

Robert let me add:
src/osgPlugins/dae/README.txt
...a while back, which was my account of how I got the thing to work. :)
Back then, it worked slightly differently... I'll try and build Collada
myself on Fedora 8, 32bit, and let you know if I have any issues.

Hi All,
In regards to the SockStream object, it would be good if the rewrite could
address some of the issues that arise with its current implementation. Namely
that its read cylce is dependent on an EOF marker being present in the file to
indicate when the end of the stream has been encountere

Hi Robert -- I'm adding code to osgOQ to clean up query IDs, and ran into a

The TXP doesn't explicitly contain its projection. You need to go back to
the TerraVista project. We can make an educated guess though; Where is your
database? City, country?
As for converting the lat/lon, OSG does not do this natively. You can use
OGR (http://gdal.org/ogr/) which is pa

Stephane,
If you TXP database is in a flat-earth projection, like UTM or state plane,
the osg::Ellipsoid functions will not help. They convert to and from
geocentric (earth-centered) coordinates.
TerraVista generates a "projInfo.txt" file along with the TXP database. This
contains the "txpOffsetX

Hi all,
have you tried compiling the plugins with "Embed Manifest = false"
(under VS2005 Project Properties->Manifest Tool->Input and Output->Embed
Manifest).
And then distributing the plugins without any manifests they should load
normally.
