+/// \class X3DExporter
+/// Class which export aiScene to X3D file.
+///
+/// Limitations.
+///
+/// Pay attention that X3D is format for interactive graphic and simulations for web browsers. aiScene can not contain all features of the X3D format.
+/// Also, aiScene contain rasterized-like data. For example, X3D can describe circle all cylinder with one tag, but aiScene contain result of tessellation:
+/// vertices, faces etc. Yes, you can use algorithm for detecting figures or shapes, but that's not a good idea at all.
+///
+/// Supported nodes:
+///		Core component:
+///			"MetadataBoolean", "MetadataDouble", "MetadataFloat", "MetadataInteger", "MetadataSet", "MetadataString"
+///		Geometry3D component:
+///			"IndexedFaceSet"
+///		Grouping component:
+///			"Group", "Transform"
+///		Lighting component:
+///			"DirectionalLight", "PointLight", "SpotLight"
+///		Rendering component:
+///			"ColorRGBA", "Coordinate", "Normal"
+///		Shape component:
+///			"Shape", "Appearance", "Material"
+///		Texturing component:
+///			"ImageTexture", "TextureCoordinate", "TextureTransform"
