I wrote a method to compute sampling distance functions, on the paper is not clear the way that how new flow line based on this distance functions are generated, because the computation of functions h1 are based on every vertex with the use of curvature defined how the dot product between normal at this vertex and the gradient field, but the gradient field was computed for every triangular face not every vertex, and other problem is that not explain how to use this sampling distance functions h1 and h2 to compute distance between line flows, how do you use this values (h1 on every vertex) inside a face, because the flow lines have different locations that vertices with h1 or h2 values.</p>
