<p>
A special convenience function, included for your pleasure. Enables the user to ignore the type of entity, and just call this method when extracting geometry. Very useful for 3D viewers that need DXF support. Check out the dxf2vrml directory for an example on how to convert a DXF file to VRML.<p>
Should be overloaded by all subclasses that have geometry, default function returns no geometry. Don't forget to transform vertices by the current transformation matrix if used in a callback from <a class="el" href="classdimeEntity.html#b1">dimeEntity::traverse()</a>.<p>
If there are coordinates, but no indices, this means running indices for the entire vertex array.<p>
Different faces and/or line segments are separated by a <em>-1</em> in the indices array, just as in VRML files.<p>
If <em>thickness</em> != 0.0, the data should, before transformation, be extruded by that length along the extrusion direction. Hence, a point becomes a line, a line becomes a quad, and a polygon becomes an object with a volume.<p>
If <em>thickness</em> == 0.0 and <em>extrusionDir</em> != (0,0,1) all the vertices should be transformed by a matrix that can be created using <a class="el" href="classdimeEntity.html#e5">dimeEntity::generateUCS()</a>. If you are using <a class="el" href="classdimeModel.html#a7">dimeModel::traverseEntities()</a> to extract the geometry, simply right-multiply the UCS matrix with the matrix found in <a class="el" href="classdimeState.html">dimeState</a> to get the correct transformation.
