    I work in 3D metrology and the consensus is right handed and Z up. Had no idea left handed existed!

      How does projection work in your field? X, Y, Z get converted to X, Z and 2D screen planars have no Y axis?

      Who invented this, why did she do it and where to send my official letter of complaint?

        TBH I’m not sure I totally understand the question but projection is very useful to decompose the orientation of elements, like a cylinder that you just measured with a machine or a scanner. The coordinates and orientation (angles) can be projected in the three main planes XY, YZ and ZX.

          Sorry for being unclear, I was talking about screen projection. For actual visualization.
