why select_vertex_id.mat and BFM_front_idx.mat are difference? #42

Closed ReverseSystem001 closed 3 years ago

ReverseSystem001 commented 4 years ago

hi, thanks for sharing this code. when i read the function transferBFM09() in load_data.py. the chosen indexes were based on BFM_front_idx.mat. why not use select_vertex_id.mat(35709, 1)??? and what is the difference between select_vertex_id.mat and BFM_front_idx.mat(35709,1)

hopes for you reply! thanks

Hi, select_vertex_id records vertex indexes in original BFM09 model(35709/53480),while BFM_front_idx records vertex indexes in the BFM model without inner mouth region(35709/53215).

thanks for your reply.  which index file（35709）do you use to pick out the indexes which was used for generate the BFM_UV. mat.  hope your reply.  thanks again.

I get stuck in the same situation because I need BFM_UV coordinates to extract UV map from vertex coloured obj file generated from this project. Sadly, author doesn't give this list for us. Anyone can guide me how to generate a BFM_UV from the obj, I would be really appreciate.

I have solved this issue. BFM_UV can be gotten by using some tools such as 3dmax, uvlayout. But it should be careful to avoid overwriting pixels while rendering colors to uv texture file.
