This crate currently provides pull parser for Binary FBX.
FBX data consists of generic node and node properties, and it requires interpretation to use as 3D contents. It is similar to relation of XML and COLLADA. COLLADA is represented using XML, but XML DOM is difficult to use directly as COLLADA data. Compare FBX to COLLADA, this crate is XML reader/writer, not COLLADA importer/exporter.
