Reading and Writing PRC Files

Since the PRC format seems to be openly documented, would it be reasonable or possible to write an independent PRC reader/writer without using the A3D SDK? My only comment is that it would be more ideal for Adobe to make the PRC parser in the A3D SDK available outside its lock-down to the Acrobat Extended Pro license, as otherwise all of this same functionality has to be replicated by someone else wanting to write their own PRC reader/writer, and maintained in the future as the PRC format evolves.

Reading and Writing PRC Files

If Adobe does not listen to you - consider opensourcing the basic PRC IO code,

since (as I guess from U3D experience) a lot of work is finding by trial-and-error

answers to questions like ''is it really implemented in Reader ver X.X in OpenGL/DirectXX mode''

and ''what the hell the doc intends to say when the number 256 is to be stored in one byte'',

you may actually benefit from the attracted guinea pigs (or, more politely, beta-testers and early adopters).

BTW, the Asymptote drawing program already has some rudimentary PRC code (just covering its needs).
