model.weights format

Hello,

Thanks again for this wonderful work!

I understand that model.weights:(5023, 5). I wanted to know what each of those 5 weights per vertex represents.

Hello, FLAME uses linear blendskinning (LBS) to articulate the head rotation around the neck, the jaw rotation, and to rotate left and right eye. The model.weights are the LBS blendweights (5 because of the 5 joints to rotate around). For a mathematical formulation please see the description in Eq. 2 of the SMPL paper
