hello,
i'm wondering if it is possible to find a rotation matrix that does not rotate about the origin.
A and B shows the standard rotation of a square about the origin. C is a square not about the origin, if i apply the rotation matrix, i end up with D, however I'd like to end up with E.
If C had the coordinates c1 (-1,1) c2 (-1, 3), c3 (-3, 3), c4 (-3, 1). It would be a rotation about (-2, 2). Is this possible?
thanks

first you shift your point to the origin by using translation matrix
then apply rotation matrix and finally apply inverse of translation matrix
