   ## 3-Byte Tangent Frame Encoding (Doom Eternal 2020)

   2

   3

   This method stores a full TBN frame using just **3 bytes per vertex** (plus a bitfield), instead of the traditional 28 bytes (normal: `vec3`, tangent: `vec4`). It leverages octahedral encoding for normals and a rotation angle for tangent reconstruction.
