But as BornToCode said, it is not actually correct to say that OpenGL uses column vectors and column major storage. Web11 de jul. de 2024 · The row-major matrix M will transform the column vector P as: P ′ T = P T M As you can see we obtain the same vector P ′ than before but transposed (i.e., as a row vector). Which is not a problem at all. As in the other case you can also interpret that matrix as sending P from local to global frame.
