Updated Draco to 1.1.0
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 a number of new compression enhancements for
|
||||||
development experience:
|
even smaller models:
|
||||||
* Stable API release
|
* Improved compression
|
||||||
* Support for npm Javascript package management
|
* Up to 40% better compression of normals
|
||||||
* Javascript based encoder
|
* Up to 5% better compression for models with multiple attributes
|
||||||
* Generalized metadata for meshes and point clouds
|
* Faster decode speeds
|
||||||
* Now supporting material properties included along with encoded file
|
* 30% faster decoding for models with multiple attributes for lower compression levels 4 and below
|
||||||
* Improved compression rates:
|
* Note: Decreases compression by 10%.
|
||||||
* 15% better compression on smaller models
|
* Encoding of metadata to .obj (e.g. Draco can preserve material or sub-object names)
|
||||||
* 40% better compression of normals
|
* Security fixes
|
||||||
* 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
