SharpGLTF is a 100% .NET Standard library designed to support Khronos Group glTF 2.0 file format.

The library is divided into these main packages:

Library	Nuget	Function
SharpGLTF.Core		Read/Write file support, and low level access to the glTF models.
SharpGLTF.Runtime		Helper classes to simplify gltf model rendering.
SharpGLTF.Toolkit		Convenience utilities to help create, manipulate and evaluate glTF models.

Additionally, there's some optional extension libraries available:

• SharpGLTF.Ext.Agi
• SharpGLTF.Ext.3DTiles

A simple example of loading a glTF file and saving it as GLB:

var model = SharpGLTF.Schema2.ModelRoot.Load("model.gltf");
model.SaveGLB("model.glb");

More examples can be found here and in the Test project.
