X3D

X3D (Extensible 3D) is an interactive 3D vector graphics format. It is the successor to VRML. It is usually encoded in XML, though there is also a standard "Classic VRML" encoding.

X3D is standardized in ISO/IEC 19775 (X3D), ISO/IEC 19776 (X3D encodings), and ISO/IEC 19777 (X3D language bindings).

Identification
Assuming uncompressed XML encoding, an X3D file has a line beginning with " ", followed by an " " XML element.

Classic VRML-encoded X3D files begin with text similar to " ".
