Hmm...I don't know why the PRC spec was removed from the web site, but I'll investigate. It's always been our intent to publicly document that format to enable development by 3rd parties.

Dear All, did anyone take a look at the 3D features that appeared in pdf 1.6 and 1.7? Is there any chance that they will be supported by gnupdf (in however remote the future) or they are not accepted in principle (too vendor-propriate, not inline with the original PDF intent, there are no 3D people around, etc)? I understand that the quaestion has nothing to do with the current state of development of gnupdf and such dergee of being "philosophical" may amount to grave offtopic AFAIK, three are two formats supported - Intel U3D - supports lines, triangles and nothing more, but was standardised at ECMA and has open-source library for writing and displaying the models - origintates from ansient Shockwave 3D. TTF PRC - very feature-rich, looks like a superset of all 3D formats that TTF company had to deal with before being acuired by Adobe. Adobe seems to be going to include PRC format in ISO PDF specs at some point of time, but for now they _removed_ the format description from their www site :(. Sincerely, Michail
