• 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

  • 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

• AGI_stk_metadata
• EXT_lights_image_based
