I've done a
osgconv test.ive test.osg
On your root .ive file and found the osgTerrain::Locator has default
settings i.e.
osgTerrain::Locator {
CoordinateSystemType PROJECTED
TransformScaledByResolution FALSE
Transform {
1 0 0 0
0 1 0 0
0 0 1 0
0 0 0 1
}
}
While I correctly get:
osgTerrain::Locator {
Format "WKT"
CoordinateSystem
"GEOGCS[\"NAD83\",DATUM[\"North_American_Datum_1983\",SPHEROID[\"GRS
1980\",6378137,298.2572221010002,AUTHORITY[\"EPSG\",\"7019\"]],AUTHORITY[\"EPSG\",\"6269\"]],PRIMEM[\"Greenwich\",0],UNIT[\"degree\",0.0174532925199433],AUTHORITY[\"EPSG\",\"4269\"]]"
CoordinateSystemType PROJECTED
TransformScaledByResolution FALSE
Transform {
1.14305877685547 0 0 0
0 0.896945953369141 0 0
0 0 1 0
-124.652221679688 41.1416664123535 0 1
}
}
This is almost certainly the root of the problem with the
visualization. I'll add some debugging into the .ive plugin to see if
the Locator exists in the file or whether it exists but with just
default settings.

This suggest an issue with compiler as much as anything else. It'd be
interesting to try gcc under windows or even better the Intel
compilers.
