  • syn

Fixed

• Removed serialization of some default values.
• extras::Void is no longer serialized.

Version 0.11.2

2018-07-08

Fixed

• JSON chunk padding is now padded with spaces (0x20) rather than zeros.
• None is no longer serialized.
• Vec is no longer serialized when empty.

Version 0.11.1

2018-06-10

Added

• payload field in Gltf in order to handle binary glTF directly.
• Error::Io enum variant.
• Gltf::from_reader_without_validation and Gltf::from_slice_without_validation.
• All functionality from the gltf-utils crate, feature gated with the new
  utils feature.
• Most functionality from the gltf-importer crate, feature gated with the
  new import feature.
• enum Uri to represent uniform resource locators.

Changed

• fn Gltf::from_* now imports binary glTF as well as standard glTF.
• fn Gltf::from_reader now requires reader to implement std::io::Seek.
• Buffer::uri now returns None in the case of binary glTF payload instead
  of the magic string "#bin".
• The POSITION attribute is now required by all mesh primitives.
• Several renames:
  • glb → binary.
  • Error::Glb → Error::Binary.
  • TrsProperty → Property.
  • InterpolationAlgorithm → Interpolation.
  • Target::path → Target::property.
  • Primitive::position_bounds → Primitive::bounding_box.
• The names feature is now enabled by default, along with utils and
  import. Rationale: Pareto principle.

Fixed

• Data structures in gltf_json now implement Serialize.

Removed

• fn Gltf::from_str -- use fn Gltf::from_slice instead.
• fn Gltf::from_value -- no longer supported.
• fn gltf::is_binary -- use slice.starts_with("glTF") instead.
• struct Unvalidated -- replaced with enum Validation.
• crate gltf-importer -- no longer supported.
