Where do the object_points come from and which in which units are they measured?

[funkfuzz]

Hi @lincolnhard,

first - thanks for the nice project.

I would like to know where do the values for the object_points come from and in which units are they?

[kirito12138]

Me too. The link in ReadMe http://aifi.isr.uc.pt/Downloads/OpenGL/glAnthropometric3DModel.cpp is not available. Could you please provide the original 3D face model points? I would really appreciate that. Thanks a lot! @lincolnhard
