[osg-users] wireframe darker wrt the surface color
Hi All, I implemented the wireframe feature as follows: Code: void addWireframe(osg::Group* root, osg::Node* scene) { osg::ref_ptr decorator = new osg::Group; decorator->setNodeMask(0x1); osg::StateSet* stateset = decorator->getOrCreateStateSet(); osg::PolygonOffset* polyoffset = new osg::PolygonOffset; polyoffset->setFactor(2.0f); polyoffset->setUnits(2.0f); stateset->setAttributeAndModes(polyoffset, osg::StateAttribute::OVERRIDE | osg::StateAttribute::ON); osg::PolygonMode* polymode = new osg::PolygonMode; polymode->setMode(osg::PolygonMode::FRONT_AND_BACK, osg::PolygonMode::LINE); stateset->setAttributeAndModes(polymode, osg::StateAttribute::OVERRIDE | osg::StateAttribute::ON); osg::Material* material = new osg::Material; material->setColorMode(osg::Material::OFF); // switch glColor usage off // turn all lighting off material->setAmbient(osg::Material::FRONT_AND_BACK, osg::Vec4(0.5, 0.5f, 0.5f, 1.0f)); material->setDiffuse(osg::Material::FRONT_AND_BACK, osg::Vec4(0.5, 0.5f, 0.5f, 1.0f)); material->setSpecular(osg::Material::FRONT_AND_BACK, osg::Vec4(0.0, 0.0f, 0.0f, 1.0f)); // except emission... in which we set the color we desire material->setEmission(osg::Material::FRONT_AND_BACK, osg::Vec4(0.7, 0.7f, 0.7f, 1.0f)); stateset->setAttributeAndModes(material, osg::StateAttribute::OVERRIDE | osg::StateAttribute::ON); stateset->setMode(GL_LIGHTING, osg::StateAttribute::OVERRIDE | osg::StateAttribute::ON); decorator->addChild(scene); root->addChild(decorator); } Now instead of having the wireframe of a fixed color, I would like to show it in a slightly darker color wrt the color of the related geometry. Is it possible? How?

Re: [osg-users] Bug in 3.4.0 when exporting .osgx file?
Hi Werner, As I explained in my previous post, the method should find the wrappers if the plugin has been already loaded, so it shouldn't be trying to reload a plugin as there would be no beneft - the code will have already checked all the possible wrappers. You haven't provided any guidance on how we might reproduce the issue so I can't say what might be wrong. The code you are looking at is likely of symptom of a problem elsewhere. Another avenue you could try is to look at the OSG master to see if fixes elsewhere in the OSG have addressed this issue. Robert.

Re: [osg-users] Bug in 3.4.0 when exporting .osgx file?
Hi Robert, the problem is here: if (osgDB::Registry::instance()->loadLibrary(pluginLib)==osgDB::Registry::LOADED) return findWrapper(name); return NULL; The loadLibrary() returns PREVIOUSLY_LOADED and not LOADED. So NULL gets returned instead of a wrapper pointer and thus the node doesn't get exported. Or am I on the wrong search path? I try exporting my scene into an .osgx file by calling: osg::ref_ptrrw=osgDB::Registry::instance()->getReaderWriterForExtension( osgDB::getLowerCaseFileExtension(_filename.toStdString())); if(!rw.valid()) returnfalse; osgDB::ReaderWriter::WriteResultresult=rw->writeNode(_node,_filename.toStdString()); result.success() is true. It creates a file containing only the outer xml header and no scene data. node is of type osg::group Am 21.03.2017 um 14:42 schrieb Robert Osfield: Hi Werner, I can't work out what might be wrong form the description.

Re: [osg-users] Bug in 3.4.0 when exporting .osgx file?
Hi Werner, I can't work out what might be wrong form the description. In general the ObjectWrapperManager::findWrapper() checks wrappers that have been registered with it first, then if it fails to find one then attempts to load plugins that may be able to provide that wrapper. If the code is getting to the find return then it's an indication that the wrapper has been found. Given this the ObjectWrapperManager::findWrapper() code looks correct. This review would suggest that the issue is likely elsewhere. What might be wrong is not something I can say at this stage.

[osg-users] [vpb] Roads
Hi, I got highway tag from the QGIS(OpenStreetMap) for roads and integrated with DEM file using VPB with following command. osgdemd -t texture/image.tif -d elevation/dem.tif --forest highway/roads.shp --height 10 --TERRAIN -o output/output.osg After that i am getting the vertices of roads from output.osg and drawing the lines above the terrain. But some places lines are going under the terrain because of different heights of terrain. For this i tried with HUD camera by setting POST_RENDER. So, i am able to see the lines even if lines are under terrain.But this is not correct method. Is there any ways to solve this problem? ... Thank you!
