The docs page on ViewMatrix states: With the setting ViewMatrix->Automatic, explicit forms for the matrix m can be found using AbsoluteOptions[g,ViewMatrix]. However, as you mentioned this does not work and the docs are evidently wrong here. I tried everything I could think of, but this is a hard nut to crack.
