All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
- Support for efficient self-managed encoding of multiple meshes. Users may use the advanced Mesh API to acquire readable mesh data for multiple meshes at once and pass the data on to new
DracoEncoder.EncodeMeshoverloads that accept saidMeshData. - Vertex attributes information (draco identifier and dimensions) was added to
EncodeResult
- Much faster encoding due to the use of the C# Job System (threads)
- Faster encoding due to avoiding a full memory copy of the result
- All encoding methods are async now
- Updated Burst dependency to version 1.8.4
- Readonly meshes now can be encoded in the Editor
- Removed Editor-only
syncparameter fromDracoMeshLoader.ConvertDracoMeshToUnityto make API stable (regardless of environment/scripting defines)
- Destroying temporary copy (instead of original) GameObject when encoding selected GameObject from the menu
- Support for encoding point clouds (thanks @camnewnham for #46)
- Point cloud encoding unit test
- Component pad byte support enables things like 3 byte RGB color vertex attributes (thanks @camnewnham for #47)
- Encoding binaries for remaining platforms (Android, WSA, WebGL, iOS and Windows 32-bit)
- Updated Draco native library binaries to 1.1.0
- 32-bit Linux binaries/support
- Unit Tests download URLs updated
- Editor imports now calculate the correct mesh bounds
- macOS binaries are now loaded on Apple Silicon properly
- Theoretical crash on unsupported indices data type. Removes compiler warning about throwing exception in C# job.
- Apple Silicon Unity Editor decoding (#34)
- Apple Silicon Runtime encoding
- WebGL library is built with Emscripten 2.0.19 now
- Minimum required version is Unity 2021.2
- Support for encoding point clouds (thanks @camnewnham for #46)
- Point cloud encoding unit test
- Component pad byte support enables things like 3 byte RGB color vertex attributes (thanks @camnewnham for #47)
- Encoding binaries for remaining platforms (Android, WSA, WebGL, iOS and Windows 32-bit)
- Minimum required Unity version is 2020.3 LTS now
- Updated Draco native library binaries to 1.1.0
- 32-bit Linux binaries/support
- Unit Tests download URLs updated
- Editor imports now calculate the correct mesh bounds
- macOS binaries are now loaded on Apple Silicon properly
- Error message when users try to run DracoUnity 3.x Unity >=2021.2 combination targeting WebGL
- Data types SInt8, UInt8, SInt16 and UInt16 on normals, colors, texture coordinates and blend weights are treated as normalized values now
- Correct vertex colors (#27)
- Point cloud support (thanks @camnewnham for #28)
- Improved render performance by reducing vertex streams for small meshes (see related issue)
- Less memory usage and better performance by creating 16-bit unsigned integer indices for small meshes
- Less memory usage by avoiding a temporary index buffer in native plug-in
- Raised version of Burst dependency to 1.4.11 (current verified)
forceUnityLayoutparameter, to enforce a blend-shape and skinning compatible vertex buffer layout
- Support for Lumin / Magic Leap
- Resolved Burst compiler errors (unresolved symbols on macOS) by setting correct native library reference (fixes #18)
- AOT Burst compilation errors
DracoMeshLoader's coordinate space conversion from right-hand (like in glTF) to left-hand (Unity) changed. Now this is performed by inverting the X-axis (before the Z-axis was inverted). Compared to the previous behaviour, meshes are rotated 180° along the up-axis (Y). This was done to better conform to the glTF specification.
- AOT Burst compilation errors
- Experimental encoding support (ability to convert Unity Meshes into compressed Draco)
- Performance improvements
- Two-step decoding allows to do more work of step two in threaded Jobs
- Utilizes Advanced Mesh API
- Uses
MeshDataArrayto shift more work to Jobs (Unity 2020.2 and newer)
- Burst
- Unit tests
- Require Normals/Tangents parameter (necessity when using Advanced Mesh API). If true, even if the draco mesh does not have the required vertex attributes, buffers for them will get allocated and the values are calculated.
- Parameter for coordinate space conversion (was on by default before)
- API is now async/await based
- Updated native Draco libraries (based on version 1.4.1)
- Support for Apple Silicon on macOS
- Support for Universal Windows Platform (x86,x64,ARM and ARM64)
- Re-built all libraries with updated environments (Xcode, Android NDK, Emscripten, etc.)
- WebAssembly lib is now built by draco CI as well
- macOS library is now excluded from other platform builds (thanks Cameron Newnham cam@fologram.com)
- Support for bone weights and joints by providing attribute IDs. Needed for glTF skinning.
- Performance improvement: CreateMesh does not calculate missing normals or tangents anymore. Instead it provides its caller with all info necessary to decide for itself, if calculations are needed.
- Support for Universal Windows Platform (not verified/tested myself)
- Removed in-Editor error by adding missing Profiler.EndSample call
- Calculate correct tangents if UVs are present (fixes normal mapping)
- Assume Draco mesh to be right-handed Y-up coordinates and convert the to Unity's left-handed Y-up by flipping the Z-axis.
- Unity 2018.2 backwards compatibility
- Reference assembly definition by name instead of GUID to avoid package import errors
- Updated Draco native library binaries
- iOS library is now ~15 MB instead of over 130 MB
- Recompiled dracodec_unity library with BUILD_FOR_GLTF flag set to true, which adds support for normal encoding and standard edge breaking.
- Opened up interface a bit, which enables custom mesh loading by users.
- Initial release
