Helper functions for glTF parsing and validation.
vtkGLTFUtils is a helper namespace that contains various functions to help with the parsing and validation of JSON-formatted glTF files. More specifically, these functions add existence and type verifications before extracting Json values. Another function helps check the document's version against supported glTF versions
