How to get uvParametrization.*.pickle #39

Thanks for your great works. I want to know the process of calculating uvParametrization.pickle, in order to replace BFM model to FLAME. Looking forward to your detailed answer.

uvParametrization.pickle contains the barycentric coordinates used to generate the texture map from the per vertex color. Flame already have these barycentric coordinates which can be found here: https://github.com/TimoBolkart/BFM_to_FLAME/blob/main/col_to_tex.py these coordinates are saved here x_coords, y_coords

U get these coordinates from the npy file here: https://github.com/TimoBolkart/BFM_to_FLAME/tree/main/data

The structure of the cached_data file can be found here in the def cache_data() function in https://github.com/TimoBolkart/BFM_to_FLAME/blob/main/col_to_tex.py

I have started working on adding FLAME to NextFace, any help is appreciated :) please let me know if u need more help with this
