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.
1. More optimized selection of prediction schemes for different
compression levels on the encoder side.
2. Improved robustness to tampered input data (.drc)
3. Added support for strognly typed vectors of bools
4. Support for logging and squared lenght to our VectorND class
5. Added support for partially defined indices in .OBJ files
6. Added support for loading of normal vectors in .PLY files
1. Add 'use strict'to example Javascript.
2. Small fixes to README.md.
3. Fix Draco compiler flag tests.
4. Fixed issue when number of quantized bits was to large.
5. Changed StartDecoding to return a value.
6. Check that num of attributes are not less than 0.
7. Check that the number of attributes is a valid value.
