: A matrix to compute normal orientation. The world transform might include non-uniform scaling, which breaks the orthogonality of the combined world-view transform. The normal matrix is used to avoid issues with the direction when transforming normals. (The normal matrix is the transpose inverse of the world-view matrix).
