glRotate produces a rotation of angle degrees around the vector (x,y,z). The current matrix (see glMatrixMode) is multiplied by a rotation matrix with the product replacing the current matrix, as if glMultMatrix were called with the following matrix as its argument: ( xx(1-c)+c xy(1-c)-zs xz(1-c)+ys 0 ) | | | yx(1-c)+zs yy(1-c)+c yz(1-c)-xs 0 | | xz(1-c)-ys yz(1-c)+xs zz(1-c)+c 0 | | | ( 0 0 0 1 ) Where c = cos(angle), s = sine(angle), and ||( x,y,z )|| = 1 (if not, the GL will normalize this vector).

Parameters:

c -
