That is the way I would do it. Maybe using a Conditional Directive. For
instance; #if, #for, #switch etc. That would give discrete camera
positions. Smooth translations between the camera positions and the look
at point can be obtained by using spline curves. It makes it more
complicated but it looks better.
Spline_Trans in Transforms.inc would be something to look at after Jay
got the basic transformations working.
