I'm attempting to load a KML/KMV file and convert it to IVE. Well, the DAE
plugin works great and the KML plugin for osgEarth works great, too. Further,
when I use osgViewere.run() after setting my new node in the scene I can see
the node in all of its 3D glory. In other words, from load to display
everything looks great and I have no issues.
When I try to save the node I get this error on the console:
image C:\Workspace\OpenSceneGraph\build\bin\models\untitled\texture.jpg' 256
128
Error writing IVE image: StateSet::write(): Unknown StateAttribute:
VirtualProgram
The file writes out to an IVE file as an uncompressed IVE stream or so the
output claims. When I try to read in the file I just saved I get an error
saying that osg couldn't find a plugin to read the IVE file. Well, garbage in
garbage out.
What is annoying is that if I have a KML without a texture there is no issues.
Even with the issue I can display the 3d object if I put it in a viewer. Also,
if I try to load and save any other type of file there is no issue. I can go
from IVE to OSG to 3ds etc without a hitch. Any ideas would be appreciated.
Please note I assume this is an OSG question since I'm having an issue with the
write node function. If you guys believe this is better handled on the
osgEarth forum let me know.
Thanks,

Code:
bool Converter::initialize()
{
// Assume failure; only set true if everything succeeds
bool succeeded = false;
// Read in the .earth file.
_earthModel = osgDB::readNodeFile("nodata.earth");
// Check for a successful read
if(_earthModel != NULL)
{
// Create the mapnode needed for reading KML/KMZ files
_mapNode = osgEarth::MapNode::findMapNode(_earthModel);
if(_mapNode != NULL)
{
// Initialization succeeded
succeeded = true;
}
}
return succeeded;
}
bool Converter::convert(std::string aFileName)
{
//osgEarth::URI uri(aFileName);
osgEarth::URI uri("C:\\Workspace\\OpenSceneGraph\\build\\bin\\doc.kml");
std::string ext = osgDB::getLowerCaseFileExtension(uri.full());
bool val = (ext == "kmz");
osg::Node* node =
osgEarth::Drivers::KML::load(uri,
_mapNode,
osgEarth::Drivers::KMLOptions());
if(node != NULL)
{
osgDB::writeNodeFile(*node, "test.ive");
node =
osgDB::readNodeFile("C:\\Workspace\\OpenSceneGraph\\build\\bin\\test.ive");
}
osgViewer::Viewer* viewer = new osgViewer::Viewer();
viewer->setSceneData(node);
viewer->run();
return true;
}
