The correct normal matrix is the inverse transpose of the model-view matrix. If you do not do any non-uniform scaling, that is scaling axises by different amounts, the inverse of the matrix is equal to its transpose because it is orthogonal. Therefore, the two operations cancel out and it is just the original matrix. farbauszugWebApr 16, 2024 · Data Types.
