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.

Subject: [pdf-devel] 3D in pdf - any plans?

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
