3D Calibration – Discussions on Profiling

I know that during class, for 3D calibration, the method has been explained as ensure the calibration is done thru the lens of a 3D glass and keep in mind that the L/R lense of each glass could be different and there could be glasses to glasses difference.
How about profiling?
Spectros were advised to be used for 3D calibration but technically u shd be able to use a colorimeter profiled. If u do, which shd be the method.
1. Build a profile in 2D using ur colorimeter to a spectro, then just stick a 3D glass on ur colorimeter and use it for 3D (technically profiling is training the spectrum (X,Y,Z) seen by the spectro with the XYZ seen by the colorimeter (but as its filtered to see the light) and a matrix is applied)
2. Build a profile in 3D again thru the lens using the spectro and colorimeter and use that profile going forward.
3. Never use a colorimeter for 3D at all for reasons I do not know as yet….
Has anyone tried this with method 1/2 and see if they are similar. I do not have a 3D display so cannot experiment with it and I doubt a client will hv the patience to wait for me to experiment on his display.
How do u do 3D?
I hv done it both ways at clients home but never had the chance to compare the 2 at the same display. Doing no1 saves time as u only need to build the profile once. In the cases where I did use this method, I did not see any major issues with the calibration results when I verified using a greyscale ramp thru the 3D glasses.
Appreciate the responses.
