		       float ux, float uy, float uz)

ARGUMENTS
       vx,vy,vz	 Specify the location of viewpoint.

       px,py,pz	 Specify the location of the reference point.

       ux,uy,uz	 Specify the view up vector.

DESCRIPTION
       EZ_LookAt defines the line of sight and a view up vector. The viewpoint
       is at [vx,vy,vz], looking at the reference  point  [px,py,pz],  with  a
