and having a quick look, i indeed read:

view <x> <y> <z> <azimuth> <elevation>::

  translate/rotate camera/viewpoint; the "up" direction will still be 
the y-axis

  default: 0 0 4 0 0


view <view_x> <view_y> <view_z> <target_x> <target_y> <target_z> <up_x> 
<up_y> <up_z>::

  set viewpoint (view_X view_Y view_Z). the camera will look at the 
target-point (target_X, target_Y, target_Z). "up" is defined via the 
vector (up_X, up_Y, up_Z)

  default: 0 0 4 0 0 0 0 1 0




i think this does pretty much explain that there can be 5 or 9 values 
(or 3 or 4, but i skipped this here) given to the [view( message and 
what they mean.
