glTF2Sharp

glTF2Sharp is a NetStandard 2.0, C# library designed to parse and create Khronos Group glTF2 files.

The current status of the library is preview alpha, but, for some cases it is probably fully usable.

Features

• glTF2 code API generated from Schema.
• Reading and writing .gltf files.
• Reading and writing .glb files.
• Logical Data Access.
• Visual Tree Access.
• Vertex and Index buffer encoding/decoding.
• Scene Evaluation.
• GPU Evaluation.
• Mesh Building utilities.
• Animation utilities.
• Material utilities
• Skinning utilities
• Morphing utilities
• Mikktspace Tangent space calculation. Help Need

TODO

• gltf.Extra field support, right now it is ignored.
• Matrix2x2 and Matrix3x3 support. This is due to missing types in System.Numerics.Vectors
• Camera API

Supported Extensions

• KHR_materials_pbrSpecularGlossiness
• KHR_materials_unlit
• KHR_draco_mesh_compression
  • Depends on Google's Draco Project which is C++ ; Help Needed
• KHR_lights_punctual
• KHR_techniques_webgl
• KHR_texture_transform
• MSFT_texture_dds
• MSFT_lod
  • When this extension is used, the model's visual tree needs to be abstracted, which requires an extensive API rework, or a full API layer.
• MSFT_packing_normalRoughnessMetallic
• MSFT_packing_occlusionRoughnessMetallic
• AGI_articulations
• AGI_stk_metadata
• EXT_lights_image_based
• EXT_texture_webp
• ADOBE_materials_thin_transparency

Alternative glTF2 c# libraries

• Khronos Group glTF-CSharp-Loader
