Use lookat or redraw?

[Brent L. Bates AAD/TAB MS294 x42854]

   I am not sure what you're asking.  Everything has to be redrawn, no
matter what you do.  The only difference I can see is whether you change
your perspective with lookat or do your movement by changing translation,
rotation, and scaling on the objects drawn.  Personally, I prefer to use
lookat most of the time, it makes most things simpler and easier to implement
and understand.
