I am trying to rotate a 2×2 plane in openGL and get the x,y,z coordinates of ABCD vertices into a matrix. Is that possible?

PS: there are two 2×2 planes in a patch below because I was trying two different methods…

it is not exactly what i was looking for, but it does exactly the same thing that i needed

Thank you Robert!!!

PS: Sorry for replying so late, I missed your answer.

I love that.
