Frmo what i know, you need to SUBTRACT the angle you want the camera to point to, from the entities. See terrabit's code for an idea.. im away from source again so i cant post how i did it :(

gluLookAt is the command you want. It takes 9 floats as parameters - the first three are the x,y,z co-ordinates of the camera, the next three are the x,y,z of the target, the last three are the x,y,z of a vector specifying which way is 'up'.
