Description
X3D (Extensible 3D) is a royalty-free open standard file format used to represent 3D computer graphics. It is used to store and interchange 3D model data, including surface geometry, color, animation, and metadata. X3D files are built on the XML standard, and can be viewed and edited with a variety of 3D modeling programs.
3D file formats are increasing by the day and this isn't a bad thing. The only quibble comes when 3D format file users have to collaborate on a file. It's impossible to work on one file when using different file formats. And that's where 3D file conversions come in.
