Class TX3DUnknownNode

Unit

X3DNodes

Declaration

type TX3DUnknownNode = class(TX3DNode)

Description

Not recognized VRML/X3D node type. Used for nodes found when parsing VRML/X3D file that are not implemented.

TX3DUnknownNode is parsed (in classic VRML encoding) in a special way, to be able to omit it gracefully. While such "unknown" node doesn't really do match in our graph, it works correctly with VRML/X3D DEF/USE mechanism.

Never instantiate this class by a standard constructor. Always use CreateUnknown constructor, this way we can safely assume that X3DType is always correctly set.
