This is a barebones glTF model viewer using the Dawn API. It is intended as a proof of concept for the API and is not a robust model viewer. It can load basic mesh/texture data from a few glTF sample models, such as:
build/examples/glTFViewer/glTFViewer path/to/Duck.gltf
build/examples/glTFViewer/glTFViewer path/to/Duck.gltf --backend metal
