Ezer éve az Adobe adott ki egy Linuxos verziót az Acrobat readerből, azt hiszem azzal mennek az ilyen tartalmak:

Illetve van egy japán faszi aki elkezdett parsert szegelni az U3D formátumhoz, anno 2016-ban rá is kérdeztem nála mi a pálya, akkor ezt írta:
Presented below is an explanation of the current situation.
The parsing library is hosted on my GitHub account here.
The implementation on the parser side is almost complete except animation and subdivision support,
but I am afraid that the library is not yet separated from the testbed written in SDL2 which means it is not in the form of an independent library.
Also the readability is quite bad as an aftermath of my struggling with the official spec.
I was planning to cut-n-paste the relevant part into evince directly and not to release the library as it is,
because it would take much time before the library could be adopted as a separate package.
In the meanwhile, I am already done with embedding OpenGL viewport into Evince,
(the forked version of Evince is here, it requires a forked version of Poppler here)
and all I need is to render the scenegraph produced by the parser,
but I have been stuck here for a while due to the lack of information about how shading is done.
(Also the target version of OpenGL is being a major problem. GLES2? GL3.0 and newer? GL2.1?)
If you could wait for a couple of weeks or so,
I would probably be able to make U3D preview in Evince work basically,
at which point I will start asking people at Evince to review.
After the current patch for glib frontend is accepted, it will not be long before Qt4 or Qt5 frontend of Poppler is equipped with 3DPDF support.
(Of course I will be very glad if you could help me with the library implementation.)
Thanks again.
Most ránéztem a repókra, és nagy mozgást sajnos nem látok ez ügyben.
Meg talán az Intelnek is volt valami parser libje, de nekem úgy rémlik, hogy az már akkor is bottal sem piszkálnám kategóriájú volt. Szóval nekem akkor úgy tűnt, hogy az Adobes Linuxos Acrobatreaderen kívül más megoldás nincs Linuxon.
