It's unclear what your input and output data is supposed to be, but
I'll guess they're both polygon meshes in 3D. Input will be a
fine-grained mesh, output should be a much coarse net that only keep
the most prominent features of the input (like the sharp turn in the
'L'). Such a task routinely occurs in constructing a series of lower
level-of-detail scenes from a high-resolution master, and the baseline
algorithm for doing that is known as mesh decimation.
