Opengl row or column major
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.

WebIt is column major only when it is used as a column matrix, and it is row major when it is used as a row matrix. Therefore, if you have a matrix A which is column major, x*A means... nothing. Well, again, it means x*A T, but that's not what you really wanted. Similarly, A*x does transposed multiplication if A is row-major.
