The
X3D propagation model applied in XGtd includes atmospheric absorption, extending the validity of its wave propagation calculations up to millimeter wave frequencies.
The RDF triples in
X3D have identified advantages and limitations to integrate and embed representation.

X3D in a highly complex and detailed Web3D world," International Journal of Computer Science Issues, vol.
Surface rendering in medicine extracts the interested surface contour of the anatomical representation from SMIs into a 3D geometrical model, which is usually stored as a VRML, VTK, or
X3D file [1,11,12].
IGES [41], STEP AP203 [42], STEP AP214 [43], and JT [44] are international standards for 3D data interchange, while VRML [45] and
X3D [46] are frequently used for 3D data visualization.
VRML was used to design virtual Web-accessible worlds but did not easily integrate with HTML which led to the eventual
X3D replacement.
Ming (2008) extended this concept by the use of the
X3D language.

For the flexibility and efficiency of implementing the domain-specific filters, Extensible 3D (
X3D) [33] and XML Path Language (XPath) [34] were applied.
