Tool to validate glTF assets.

Validation is performed against glTF 1.0.1 draft with asset.version check disabled.

Validator outputs a validation report (in JSON-format) with all found issues and asset stats.

Implemented features

• JSON syntax check
• All properties and their types from JSON schemas (including limitations on valid values).
• Validity of internal id references.
• Object-specific checks (compatibility of interlinked dictionaries, property combinations, etc).
• Correctness of Data URI encoding.
• .glb file format from KHR_binary_gltf extension.
