An Industry Standard. The Acrobat Reader, now in it's ninth version, is the industry standard digital document publishing format. PDF files are as universal for documents as GIF and JPEG files are for Graphics. Acrobat Versions 7, 8 and 9 all have a powerful i3D "engine" inside of the Acrobat Reader, so there are no extra plug-ins to download or install.
High Quality i3D. Acrobat 3D, in Acrobat since Reader 7, now offers advanced 3D and i3D capabilities to PDF users. The 3D rich media can be processed by the PC's CPU or by it's Hardware Graphics Architecture (GeForce/Radeon 3D chipsets), so that even without hardware-3D your simulation will always look photoreal and animate smoothly.
Viral X!Factor! PDF files are readily sent via e-mail and internet servers, and since everyone has the Acrobat Reader software, the files are instantly viewable. This means that if your PDF document is small enough in filesize (say 64KB up to 512KB) and i3D it will have a good probability of being forwarded or resent to other end-users.
Small File Sizes. Due to the nature of i3D, an interactive 3D simulation can actually be created in fewer bytes (2K-64K) than a static image (24K-240K). This is because the data for an i3D scene is simple text values for geometry, animation & programming.
