#GLTF Deserializer/Serializer in C++

  • Fully compliant with KhronosGroup GLTF 2.0 spec
  • Can ingest GLB/GLTFs as well as GLTFs with embedded Base64
  • Support for extensions
  • Built-in compliance validation during deserialization
  • Low memory overhead
  • Simple interface for reading any model information automatically converted to any bit size
  • Flexibility and ease of integration to any 3D engine
  • macOS/Windows Compatible

GLTFSDK is a fully compliant Deserializer/Serializer for GLTF, GLB and Base64 encoded GLTF files, implemented in C++ 11. Designed for flexibility and ease of integration into 3D engines. It supports files containing extensions and extras, allows easy direct reading of any model information into vectors of any desired bit size, and has built-in compliance validation of files during deserialization. Available for both Windows and macOS.
