How-To Fledermaus - Create a flightpath for movie making
This article describes an alternative method using mouse navigation for creating a flightpath for a movie. It is possible (and often easier) to create a flight path by using the "geopicking" selection mode available in Fledermaus. This workflow is geared towards users without access to a 3D Space Navigator.
1 - Make a flightpath from surface points
Enter "Select" mode or hit the "S" hotkey
Pick the points along the path you wish to create in your scene
From the Geopick tab (near the Object Attributes window), export your geopick table as ASCII
2 - Import the flightpath created
From the "Create" menu, add a Camera. In the Object Attributes window, select the "Time" tab
From the "Options" button, select "Import XYZ Flightpath"
Import the XYZ that you created when you exported your geopick table. Set your start time to 0:00:00 and your end time to however long you'd like your fly-through to be (for example, 00:02:30 for 2.5 minutes). Select an appropriate z-offset for your data (this is in whatever unit your data is in), and set a downward facing camera angle. This may require some playing around- if you import your flight path and find that your offset is much too large or small, it only takes a second to re-import and try a different value.
The keyframe window under your time tab for your camera will now be populated with the x,y, and z locations from your geopick table.
3 - Work with the flight path created
Use the edit tools to smooth camera angles, rotate camera, and change camera positioning. You can move from keyframe to keyframe in the "time" tab and change the position of the camera at each point.
When you've finished creating your flight path, you can press "play", or render a movie to be viewed outside of Fledermaus.
