[Manifold-l] fly-through: definition of 3D-trajectory possible?

[Dr. Harald von der Osten]

Thanks Martin for your reply.

What I would like to do is to create a short video for presentation in a museum.
With the fly-through people should see the area where the museum is situated and
they should get an overview of archaeological sites (of this area) already
known. This would be a fly in a more or less constant height. But then I would
like to circle around a special place and to reduce the height of the camera
showing the results of a new prospection, uncovering a roman house of 120 m by
70 m (reducing the speed of the fly and stopping in a specific distance to the
object).

Thanks again.
Harald
