Hi! I'm trying to add a "dashed line" between two points (for now, they're hardcoded. They exist in the point cloud that is already in the scene).
With this code I expected two blue points of size 10 in the same place of those in the point cloud and a dashed line between them, yet nothing is shown. Do you know what the problem may be? Here's the last piece of code I tried: osg::ref_ptr<osg::Vec3Array> dash_points = new osg::Vec3Array; osg::ref_ptr<osg::Vec4Array> dash_color = new osg::Vec4Array; osg::ref_ptr<osg::Geometry> dash_geometry( new osg::Geometry); dash_color->push_back(osg::Vec4f(0.0,0.0,1.0,1.0)); const osg::Vec3f P1(525501.015,4668653.861,457.197); const osg::Vec3f P2(525510.287,4668630.738,457.034); dash_points->push_back(P1); dash_points->push_back(P2); qDebug() << "DASH"; qDebug() << "\tP1:" << P1[0] << P1[1] << P1[2]; qDebug() << "\tDASH_POINTS[0]:" << (*dash_points)[0][0] << (*dash_points)[0][1] << (*dash_points)[0][2]; qDebug() << "\tP2:" << P2[0] << P2[1] << P2[2]; qDebug() << "\tDASH_POINTS[1]:" << (*dash_points)[1][0] << (*dash_points)[1][1] << (*dash_points)[1][2]; dash_geometry->setVertexArray(dash_points.get()); dash_geometry->setColorBinding(osg::Geometry::BIND_OVERALL); // The 1,0xf0f0 parameters were taken from one of the examples... osg::ref_ptr<osg::LineStipple> linestipple( new osg::LineStipple(1,0xf0f0) ); dash_geometry->getOrCreateStateSet()->setAttributeAndModes(linestipple.get(), osg::StateAttribute::OVERRIDE ); dash_geometry->addPrimitiveSet( new osg::DrawArrays(GL_LINES,0,dash_points->size()) ); dash_geometry->getOrCreateStateSet()->setAttributeAndModes( new osg::Point(10.0f) ); dash_geometry->addPrimitiveSet(new osg::DrawArrays(GL_POINTS, 0, dash_points->size())); dash_geometry->setColorArray(dash_color.get()); shape->addDrawable( dash_geometry ); shape->addDrawable(text); Thanks and best regards! PS: I can show a "complete" line between the points. I thought that the code would be similar, just adding the LineStipple part.
