### My Question

How to translate a mesh in m unit?

I have a model predicted translation of 3d human mesh, it was in m unit, something like this:

[0.07, 0.08, 11.45] -> x y z

z is distance from mesh to camera

How can I visualize such movement in open3d? Currently the z movement is too large for a single 0.1 offset.
