Final project (optimizing surface parametrization)

We start with a given parametrization of a mesh based on the paper "ABF++: Fast and Robust Angle Based Flattening"  and optimize it using a gradient based technique, on the subdivided surface, according to the technique described in  the paper "Parametrizing subdivision surfaces".  We applied these results to the mesh "Bimba" which was already parametrized using ABF.  This project was developed at the Course "Geometric processing", taught by Luiz Henrique de Figuereido and Luiz Velho.  To get the results, the following pipeline was applied:

Bimba, original parametrization and first iteration (getting worse)

Bimba, original parametrization and second iteration
