G3N to U3D Conversion: FAQ

What are G3N files?

G3N files contain digitally archived documents that were sent or received using Imaging Fax, a currently obsolete application that allowed computers equipped with modems to communicate with independent fax machines. Such images are stored using Group 3 compression, which provides an optimal minimisation of file size through a line-by-line compression of text and helps effectively compress white space. Group 3 compression was superseded by Group 4, providing a lossless compression of black-and-white images. G3N files are now considered uncommon.

What are U3D files?

U3D (Universal 3D) is a standardized file format used to store and exchange 3D models and scenes. It supports geometry, textures, colors, lighting, and animations, allowing complex 3D content to be represented efficiently. U3D is best known for its use in interactive PDF documents, where users can rotate, zoom, and explore embedded 3D models. The format is widely used in engineering, architecture, manufacturing, medical imaging, and scientific visualization.
