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 "<!DOCTYPE X3D PUBLIC", followed by an "<X3D>" XML element.

Classic VRML-encoded X3D files begin with text similar to "#X3D V3.1 utf8".
