Description

The OFF file format is a simple text-based format capable of storing 2D and 3D geometry and was originally developed for the Geomview application. There is also an extension to the OFF format used by the Stella4D application to enable storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shape, edge information and also has support for including color information. As the format is text based the files can become rather large with no built-in compression options available.

Description

The IDTF file format is a bespoke format that enables interactive 3D content to be embedded within a PDF document. Currently only Adobe Reader and PDF-XChange Editor are able to render PDF documents that contain this 3D content.

IDTF files are a simple text-based format containing 3D geometry defined using vertices and faces in a structured hierarchy. Prior to importing the IDTF file to the PDF it must be converted to a U3D file format using one of the free applications such as IDTFConverter.
