How to get Yaw, Pitch and Roll from a 3D vector

Question

I have a direction vector that applied to a position gives me the point at which the camera should look. How can I get from that yaw, pitch and roll in order to use glRotate

Answer 1

pheelicks's equations are wrong. Dear future googlers, here you got what's working:

Assuming pitch: rotation by X axis, yaw: rotation by Y axis, roll: rotation by Z axis. Direction vector V(x,y,z)

pitch = asin(V.y / length(V));
yaw = asin( V.x / (cos(pitch)*length(V)) ); //Beware cos(pitch)==0, catch this exception!
roll = 0;
