This is not implemented (yet). The only supported VertexArray format is Vec3, see include/osg/TemplatePrimitiveFunctor and include/osg/TrianglePrimitiveFunctor. Feel free to implement and submit it! Up until very recently double precision was not supported by OpenGL-Hardware at all and therefore the broad use of doubles has been discouraged in OSG. Even if your hardware and drivers support double precision you will still suffer a very large performace penalty (think a factor of 5 to 8 slower). So you should still ask yourself if you really need vertex arrays with double precision. Transformation matrices are handled with double precision by OSG and there is database paging for very large DataSets. > But i choose to store it as a double, ie > osg::Vec3dArray and set it in the geometry as > geometry->setVertexArray(vec3d_vertArr) > > then point picking fails using the same PolytopeIntersector. > below is a the code for detecting the intersections > > >[...] > > > Whats the solution?
