Implementation Details
Unity glTFast uses JsonUtility for parsing, which has little overhead, is fast and memory-efficient (See https://docs.unity3d.com/Manual/JSONSerialization.html).
It also uses fast low-level memory copy methods, the C# Job System, Mathematics, the Burst compiler and the Advanced Mesh API.
