The right side contains two vectors in an array. The first vector gives the x axis direction This is normalized to unit length. The second vector gives the positive y direction in the xy plane. This vector is adjusted to be unit length and perpendicular to the x direction. Defined in serialization/IModelJsonSchema.ts Line 200 Last Updated: 11 June, 2024
