WebThe only transformations we want to do to on them are rotations and translations. Matrix multiplication can encode both rotations (NxN matrix) and translations (we need one extra dimension). Rotation matrices have explicit formulas, e.g.: a 2D rotation matrix for angle a is of form: cos(a) -sin(a) sin(a) cos(a) http://www.learnopengles.com/tag/transformation-matrix/ graphic design in the post digital age pdf https://telgren.com
