Since your data consists of locally 2D elements (triangles, not gets) you might have better luck with both LIC and streamlines if you first apply the "Surface Vectors" filter. This constrains the vector data such that it is always tangential to the local surface.
Also, another option for vector visualization you might try is the Warp be Vector filter, which bends the geometry according to the local vector field. David E DeMarle Kitware, Inc.
