I can't remember where people were talking about arrows in 3d with Sage being broken in Sage 9,Actually, the above ticket regards plots of individual vectors. But both plot_vector_field3d() and arrows3d() work well with Sage 9.0 and the default three.js viewer. So I am puzzled: which issue are you referring to?
