How to convert Deep3DFace reusult mesh to flame？

[skeras]

Hi,
This project use standard BFM2009 convert to FLame, but deep3dface (https://github.com/sicxu/Deep3DFaceRecon_pytorch.git) generate mesh is not standart (71418,3), how to convert this mesh to flame？
Thanks a lot!

Can you provide one Deep3DFace mesh for reference?

Thanks for your reply.

Sorry, I missed that. Deep3DFace uses BFM as underlying model. Do you have the vertex indices of those cropped faces?

I have the same problem as well.

[LinShiqi047]

    # vertex indices for each face. starts from 0. [F,3]
    self.face_buf = model['tri'].astype(np.int64) - 1
    # vertex indices for 68 landmarks. starts from 0. [68,1]
    self.keypoints = np.squeeze(model['keypoints']).astype(np.int64) - 1

    if is_train:
        # vertex indices for small face region to compute photometric error. starts from 0.
        self.front_mask = np.squeeze(model['frontmask2_idx']).astype(np.int64) - 1
        # vertex indices for each face from small face region. starts from 0. [f,3]
        self.front_face_buf = model['tri_mask2'].astype(np.int64) - 1
        # vertex indices for pre-defined skin region to compute reflectance loss
        self.skin_mask = np.squeeze(model['skinmask'])

I look up your code and the sparse matrix,and the sum of each row , I found that your processing of bfm to flame is to generate vertex of flame with weighted vectices of bfm, so how you get the weight
