]What I did this week

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.

To resolve this problem, i am reading these papers

vector fields G1 and G2.
