Question about the translation vector

Hi, I am doubting that how does you get translation vector working as camera location? In my own monocular video, the translation vectors do not shift a lot.

Since nerf requires static object at a canonical space and cameras revolving around it, we use the transformation matrix of the rigid head tracking as the camera rigid transformations. (And then normalize the translation such that average z is at 0.5, because for nerf you want the scene to be bounded within the unit cube).

Thanks for your reply! I am actually using the rigid head tracking as the camera rigid transformation as well. However, when trying to render using the render function you provided, the mesh can't be matched to the face. I am wondering whether the fx is negative when you do rendering? And what is the coordinate system you use? Many thanks!
