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
-Increase version to 1.0.1
-Update Javascript decode timing example
-Fix async creation of DracoDecoderModule
-fixes wasm parallel decoding
-Introduce base class for geometric normal predictor
-Added integer attribute interface to JavaScript decoder
-Move loading Draco decoder into three.js Draco loader
-Add compiler launcher support to CMake build
-Add sanitizer support via CMake build
-Check we are not reading past the end of the attribute buffer
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
Changes:
1. Javascript decoder can now be built separately for meshes and point
clouds. Together with other optimizations this results in about 33%
smaller Javascript for mesh decoder. (pre-built javascript for meshes
and point clouds is included).
2. Fixing bug in our symbol_encoder that resulted in failed encoding for
certain cases when there were around 1<<18 symbols.
3. Changing default setting of our draco_encoder app to -cl 7
1. Javascript decoder is now exported as a module using DracoModule()
function that needs to be instantiated on the client.
2. Updated Javascript example applications and README.md
3. Added normalization function to VectorD
4. Added support for converting a single signed value to symbol for
entropy coding and vice versa
5. Minor code cleaning
1. Added support for loading sub-objects in .OBJ into a generic
attribute.
2. Added missing mesh_are_equivlent classes needed for certain unit
tests.
3. Updated javascript decoder reflecting our latest changes + added
support for GeometryAttribute::custom_id() method.
4. Added checks for valid quantization bits to our draco_encoder app.
