Ok thanks to Sneftel , I finally understood the use of modelview matrix . But could someone explain to me how the Billboarding example from "OpenGL Game Programming" book works because I have problems in understanding it? I can''t understand why we transpose the matrix and why we don''t use directly the up and right vectors of the modelview matrix(which I assume are the fisrt two columns of the 3x3 submatrix). Thanks
