Hi, a simple line drawing code is below but i'm sure you want more complicated solition. Below you can update the start and end points on the fly by osgGA mouse movement.
Code: osg::Vec3 sp(0,-180,120); osg::Vec3 ep(0,480,120); osg::ref_ptr<Geometry> beam( new osg::Geometry); osg::ref_ptr<osg::Vec3Array> points = new osg::Vec3Array; points->push_back(sp); points->push_back(ep); osg::ref_ptr<osg::Vec4Array> color = new osg::Vec4Array; color->push_back(osg::Vec4(1.0,0.0,0.0,1.0)); beam->setVertexArray(points.get()); beam->setColorArray(color.get()); beam->setColorBinding(osg::Geometry::BIND_PER_PRIMITIVE); beam->addPrimitiveSet(new osg::DrawArrays(GL_LINES,0,2)); Thank you!
