The drawback of this technique is that my code would be less portable, supporting desktop GL only, since most mobile platforms do not seem to support this feature yet in OpenGL ES 2.0. Creating matrix transformations in the shader. 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)
