• Support for the KHR_materials_variants extension.
• Support for the KHR_materials_volume extension.
• ExactSizeIterator implementation for Joints iterator.

Changed

2020-01-18

Added

• Support for the KHR_materials_unlit extension, which adds an unlit field
  to Material.
• ExactSizeIterator implementations for accessor iterators.

Fixed

2019-10-06

• import_slice function.
• Clone and Debug implementations for Material.
• accessor::util::SparseIter and accessor::util::SparseIndicesIter which
  iterate over items and indices in sparse accessors respectively.

• The original version of accessor::util::Iter has been renamed as ItemIter.

2019-07-27

Added

• Support for the KHR_lights_punctual extension.
• gltf-roundtrip example.

Changed

• Renamed validate_minimally as validate.
• Removed dependency on cgmath.

Fixed

Removed

• Trait function Validate::validate_completely and its implementations.

2019-04-21

• Updated the following dependendies:
  • approx
  • base64
  • cgmath
  • image
  • lazy_static
  • proc_macro2
  • quote
  • syn

Fixed

• Removed an unused field in Accessor which was a cause of poor performance.
• Borrow checker complaint regarding Glb::from_reader.

2019-02-21

• Support for the KHR_materials_pbrSpecularGlossiness extension.
• Extra Eq and PartialEq implementations.

Fixed

• Accessor::min is no longer serialized if None.
• Extras::_allow_unknown_fields is no longer serialized.
• bufferView.byteOffset is now optional.
• Node translation/rotation/scale values are now optional.
• Removed serialization of some default values.
• extras::Void is no longer serialized.

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.

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.
• Node::matrix -- use transform().matrix() instead.
• Node::rotation -- use transform().decomposed() instead.
• All hidden as_json functions -- no longer supported.

Fixed

• gltf_utils::AccessorIter::new is marked pub again.

2018-03-04

  to allow loading of binary glTF data on non-little-endian machines.
• More descriptive errors in the gltf and gltf_importer crates.
• Gltf::skip_validation is no longer marked unsafe.
