We hear very often the question whether a 3D format is supported in Acrobat 9 Pro Extended, and in some cases the response is a) "yes, all current versions", or b) "yes, up to version X", or c) "no, it is not supported". On the same subject of formats, there is increasing interest in the 3D format representation inside PDF called PRC, with questions being asked such as a) “is the PRC format open” or b) “are the specifications accessible” or c) “is there an SDK to read and write PRC”.
In this article, I will try to address all these questions by providing short answers when possible and by introducing the new Acrobat 3D SDK that is now available as part of the Acrobat 9 SDK that is now live. So, please read on and feel free to ask any additional questions using the comments form.
