* Improved kD-tree based point cloud encoding
* Now applicable to point clouds with any number of attributes
* Support for all integer attribute types and quantized floating point types
* Improved mesh compression up to 10% (on average ~2%)
* For meshes, the 1.3.0 bitstream is fully compatible with 1.2.x decoders
* Improved Javascript API
* Added support for all signed and unsigned integer types
* Added support for point clouds to our Javascript encoder API
* Added support for integer properties to the PLY decoder
* Bug fixes
* Up to 20% faster decoding
* Added support for integer attributes to our Javascript Encoder
* Fixed issues with THREE.DracoLoader not releasing memory associated
with the Draco module
* OBJ decoder can now be used to parse pure point clouds
* Added Unity plugins to support runtime loading and design-time
importing of encoded Draco files
* Javascript and WebAssembly decoder size reduced by 35%
* Added specialized Javascript and Webassembly decoders for GLTF (size
reduction about 50% compared to the previous version)
The latest version of Draco brings a number of new compression
enhancements for even smaller models:
- Improved compression
- Up to 40% better compression of normals
- Up to 5% better compression for models with multiple attributes
- Faster decode speeds
- 30% faster decoding for models with multiple attributes for lower compression levels 4 and below
- Note: Decreases compression by 10%.
- Encoding of metadata to .obj (e.g. Draco can preserve material or sub-object names)
- Security fixes
The latest version of Draco brings many new enhancements to improve the
development experience:
* Stable API release
* Support for npm Javascript package management
* Javascript based encoder
* Generalized metadata for meshes and point clouds
* Now supporting material properties included along with encoded file
* Improved compression rates:
* 15% better compression on smaller models
* 40% better compression of normals
* Performance improvements (~10% faster encoding, decoding)
* Reduced GPU memory usage:
* Option to store decoded quantized attributes
* Support for triangle strip connectivity on decoded meshes
* iOS 9 Javascript decoder
* Bitstream specification now available
