i am missing something and it's buggin me. i have a lookat vector defined as such vec3 vLookAt = vec3( 1.0f, 0.0f, 0.0f ); // Look +x direction now how do i get the Euler angles for each wx, wy, wz. thanks much

Code makes the man

One way is to construct the matrix, then extract the euler angles from it. The other way, given a suitable order of rotations, is to convert the vector to spherical coordinates and take theta and phi as two of the angles (the third angle being zero).
