Hi Andreas,
indeed, this fixed it. The aspects are more or less synchronized now.
I still can't see my geometry.
I exported the scenegraph in aspect 1. The vertex position indices show up in
the .osg file. However, they don't show up when I export the scenegraph
in aspect 0. The vertex positions, vertex colors and primitive type/length
values
are available in both aspects, though.
Here is a snippet of my code that builds up the osg::Geometry node core:
//-- primitve types and length values
osg::GeoPTypesUI8Ptr meshPTs = osg::GeoPTypesUI8::create();
osg::GeoPLengthsUI32Ptr meshPLs = osg::GeoPLengthsUI32::create();
osg::GeoPTypesUI8::StoredFieldType &meshPTsData = meshPTs->editField();
osg::GeoPLengthsUI32::StoredFieldType &meshPLsData = meshPLs->editField();
// fill meshPTsData and meshPLsData
//-- vertex positions
osg::GeoPositions3fPtr meshVertices = osg::GeoPositions3f::create();
osg::GeoPositions3f::StoredFieldType &meshVerticesData =
meshVertices->editField();
// fill meshVerticesData
//-- vertex position indices
osg::GeoIndicesUI32Ptr meshVertexIndices = osg::GeoIndicesUI32::create();
osg::GeoIndicesUI32::StoredFieldType &meshVertexIndicesData =
meshVertexIndices->editField();
// fill meshVertexIndicesData
//-- vertex color indicies (optional)
osg::GeoIndicesUI32Ptr meshColorIndices = osg::GeoIndicesUI32::create();
osg::GeoIndicesUI32::StoredFieldType &meshColorIndiciesData =
meshColorIndices->editField();
// fill meshColorIndicesData
//-- create geometry node core
osg::GeometryPtr meshGeometryCore = osg::Geometry::create();
//-- supply primitve data and vertex positions/colors
meshGeometryCore->setPositions(meshVertices);
meshGeometryCore->setTypes(meshPTs);
meshGeometryCore->setLengths(meshPLs);
if (hasNodeProperties || hasElementProperties)
{
#ifdef IFX_POST_CLASSIFICATION
osg::GeoTexCoords3fPtr meshScalars = osg::GeoTexCoords3f::create();
meshGeometryCore->setTexCoords(meshScalars);
#else
osg::GeoColorsPtr meshColors = osg::GeoColors3f::create();
meshGeometryCore->setColors(meshColors);
#endif
}
//-- supply vertex indices
meshGeometryCore->setIndex(meshVertexIndices, osg::Geometry::PositionsIndex);
if (hasNodeProperties) // simply reuse meshVertexIndices
meshGeometryCore->setIndex(meshVertexIndices,
osg::Geometry::ColorsIndex);
else if (hasElementProperties)
meshGeometryCore->setIndex(meshColorIndices,
osg::Geometry::ColorsIndex);
//-- set core geometry node
vmn.geometryNode->setCore(meshGeometryCore);
//-- supply vertex colors
updateMeshColors(...);
Any ideas?
