Your triangulation consists of just two triangles, the first with vertices
(0, 0) (0.1, 0.1) (0.1, 0.1) and the second (0, 0), (0.1, 0.1), (0, 0).
Each of these triangles has duplicate vertices and is therefore a straight
line.
In fact you only have three distinct points in your points.dat file, at (0,
0), (0.05, 0.05), and (0.1, 0.1). You can never construct a triangle which
isn't a straight line with these points. Perhaps you intended your
points.dat file to be something like
0 0
0 0.05
0 0.1
0.05 0
0.05 0.05
0.05 0.1
0.1 0
0.1 0.05
0.1 0.1
