public class VRML97
extends java.lang.Object

Static public methods about the VRML specification. This class contains information about all VRML 2.0 nodes, fields, and default field values. It has static public methods for accessing this information, and is used mainly by the parser.

Since:
1.1
Version:

For example, a Transform "scale" value is restricted to positive values, but its data type is SFVec3f. Vorlon defines the type as a PositiveSFVec3f to implement this restriction.
