Breaking changes:

• Stricter type checking.
• External type definitions are now installed as dependencies.

v0.7

• Add EXT_texture_webp extension.
• Add KHR_materials_sheen extension.

Breaking changes:

• Merged TextureSampler properties into TextureInfo.
• TextureInfo now extends from ExtensibleProperty.
• Simplified I/O API. Renamed:
  • NativeDocument -> JSONDocument
  • unpackGLB -> readBinary
  • packGLB -> writeBinary
  • createDocument -> readJSON
  • createNativeDocument -> writeJSON
  • unpackGLBToNativeDocument -> binaryToJSON

v0.6

Milestone

Features:

• Add world transform API (getWorldTranslation/getWorldRotation/getWorldScale/getWorldMatrix) and getMatrix to Node.
• Add ColorUtils and helper methods to work with colors in hexadecimal and sRGB.
