Editing X3D (section)

== Example ==
<syntaxhighlight lang="xml">
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE X3D PUBLIC "ISO//Web3D//DTD X3D 4.0//EN" "http://www.web3d.org/specifications/x3d-4.0.dtd">

  <Scene>
    <Shape DEF="MyTriangle">
      <IndexedFaceSet coordIndex="0 1 2">
        <Coordinate point="0 0 0 1 0 0 0.5 1 0"/>

The VRML representation is the same as {{section link|VRML|Example}}, except that the version numbers are changed to reflect the latest X3D standard (<code>#X3D V4.0 utf8</code>).  An identifying DEF name is also applied as a node identifier (id).
