+/// Pay attention that X3D is format for interactive graphic and simulations for web browsers. aiScene can not contain all features of the X3D format.

+/// "MetadataBoolean", "MetadataDouble", "MetadataFloat", "MetadataInteger", "MetadataSet", "MetadataString"
+/// Geometry3D component:
+/// "IndexedFaceSet"
+/// Grouping component:
