Web2 de jun. de 2015 · You need a vector representing the direction you are facing (0,0,-1), one representing upwards (0,1,0) and one vector representing camera position. After rotating the lookat vector you can then translate your position in the direction of the vector. Afterwards you can easily construct the ModelView matrix using the three vectors.
