Manipulating matrix, and changing rows and columns

hello, I have a rotation matrix that in theory points z down, y left and x pointing out of the screen.
I would like to convert it to opengl, but not rotating it, but with rows and columns swapping.
The problem is that i don’t know how they work.
Can somebody enlightme or point me to a resource to learn about it (the effect of changing rows and columns in a rotation matrix)


Sounds like your matrix is left handed. In this case, flip the z axis will convert it to right handed. Also, OpenGL matrix is column major, so you need to transpose your matrix to get that if yours is row major.
