After a couple of tests here are my findings
*) The preview does not work at this moment. I only see a light blue square which can be activated. After which the 3d viewer shows the embedded 3d image The developers are waiting for some functions to appear in luatex before doing the preview "the right way". I have a patch implementing preview "somehow".
*) Specifying several views as shown in back-u3d.mkiv shows up in the resulting pdf as "unknown view" Most likely a typo bug in lpdf-u3d (at the start of make3dview - if you are listening, Hans ;) Have a fix for that too.
*) I also experimented with different values for coo, c2c, roll etc. When not specifying any of these settings the embedded 3d is always shown with the incorrect roll i.e the roll is always 90 degrees off
Most likely my fault, but there are different points of view on what is default camera position (moview15, Asymptote, OpenGL, U3D, Adobe Viewer), so most likely the default default is not the one Asymtote expects. Plus Asymptote is micromanaging things - it not only sets camera, but also moves the model itself, to be better seen, apparently. We'll have to dig into that someday - see you on Asymptote forum if you wanna play and have time for technicalities. Sincerely, Michail PS. Sorry for slow answer - had to fix Asymptote PRC output first.
