3D PDF

In the past, various 3D formats (such VRML, 3DS, 3DMF, and o2c) have been touted as 'the 3D PDF' (portable document format). But their opportunity to become the de facto standard may have passed. In January 2006, Adobe unveiled its own 3D format software, called Adobe Acrobat 3D, which actually uses the latest PDF file format. As with those other formats, a free viewer is available.
