Mathematica Import/Export Format

X3D (.x3d)

MIME type: model/x3d+xml
Web3D geometry format.
Used for distributing 3D models on the web and in media applications.
XML format.
Can store multiple geometries.
Introduced in 2003, maintained by the Web3D Consortium.
Successor of the VRML format.

Export supports the X3D format Version 3.0.

EXPORT

Export["file.x3d", expr] exports a Graphics3D object to an X3D file.

Export["file.x3d", expr, elem] creates an X3D file by treating expr as specifying element elem.

Export["file.x3d", {expr₁, expr₂, ...}, {elem₁, elem₂, ...}] treats each expr_i as specifying the corresponding elem_i.

Export["file.x3d", expr, opt₁->val₁] exports expr with the specified option elements taken to have the specified values.

Export["file.x3d", {elem₁->expr₁, elem₂->expr₂, ...}, "Rules"] uses rules to specify the elements to be exported.

See the reference pages for full general information on Export.

ExportString supports the X3D format.

ELEMENTS

Data representation elements:

	"Graphics3D"	X3D file containing 3D geometries, represented as a Graphics3D object
	"GraphicsComplex"	list of GraphicsComplex objects, each representing a geometry stored in the file
	"LineData"	lines represented as lists of indices, referencing the vertices as given by the "VertexData" element
	"LineObjects"	list of Line primitives given in absolute coordinates
	"PointData"	point data in indexed form
	"PointObjects"	list of Point primitives given in absolute coordinates
	"PolygonData"	polygon data in indexed form
	"PolygonObjects"	list of Polygon primitives given in absolute coordinates
	"VertexData"	list of vertex coordinates
	"VertexNormals"	normal vectors corresponding to the vertices given by "VertexData"

OPTIONS

Advanced options:

	"InvertNormals"	False	whether to invert the orientation of vertex normals
	"VerticalAxis"	{0,0,1}	orientation to assume for the coordinate system used in the file

By default, Mathematica assumes that in the coordinate system used by the X3D format the vertical axis corresponds to the third coordinate.

With the setting "VerticalAxis"->{0, 1, 0}, Mathematica will apply the transformation {x, y, z}->{x, z, -y} to all graphics coordinates when exporting to X3D.
