This table outlines FreeWRL's complance to the Web3D VRML Specifications.

NOTE 1: FreeWRL aims to support full conformance in some nodes to the full VRML 97 spec, not only to the Base spec.

NOTE 2: Thomas Flynn has volunteered to independently confirm FreeWRL's VRML97 conformance at: http://members.rogers.com/tflynn/freewrl-conformance.html
