Hi Otto, I suggest downloading the code for http://demonstrations.wolfram.com/FlightThroughAStarCluster/ contributed by Frederick Wu and http://demonstrations.wolfram.com/CameraAnimationsOnCirclesSpiralsHelicesAndConicalSpirals/ contributed by Andreas Filler. These would be a great starting code examples that with your own modifications will let you learn the intricacies of ViewPoint, ViewVector, ViewCenter, etc ... The Demonstrations project is generally a good place to refer to when first struggling with how to implement a new project using Mathematica. Hope that helps ...
