Draco Mesh Compression for Blender

Draco encoding and decoding for glTF-Blender-IO.

The Blender repository has copies of the files in src and the required Draco source files located in <blender-root>/extern/draco.

Changes

Blender does not need to be built locally to test changes in Draco or the bridging code.

• Build the target extern_draco
• Set the environment variable BLENDER_EXTERN_DRACO_LIBRARY_PATH to the built dynamic library
• Launch Blender and export with compression enabled or inspect the console output if compression options are missing

Release

• Checkout the Blender source code repository
• Copy all changed files to <blender-root>/extern/draco
• Open a new Blender Differential
