Properties
| Name | Visibility | Description | |
|---|---|---|---|
| AutoSpeed | public | Controls whether segment speed is calculated automatically from the prepared path. | |
| Camera | public | Provides access to a camera at the specified index. | |
| CameraActive | public | Access to the Active property of a camera. | |
| CameraName | public | Access to the Name property of a camera. | |
| Count | public | Camera count. | |
| FPS | public | Target FPS (frames per second). | |
| Looped | public | True if the animation should loop. | |
| PathType | public | Interpolation method used to prepare the animation path. | |
| Running | public | True if the animation is running. | |
| SpeedFactor | public | Animation speed; 1.0 is default, set to less than 1.0 to slow down and greater than 1.0 to speed up. | |
| TimeSpan | public | Timespan of the animation (in seconds). | |

| ViewerWnd | public | Attached 3D viewer. | |
Remarks
PURPOSE: Manage a collection of 3D camera keyframes, build an interpolated animation path from active cameras, and control playback in an attached 3D viewer.
BEHAVIOR: The class can capture the current viewer camera, reorder and activate cameras, prepare a path using the selected interpolation method, and then start, pause, restart, reset, stop, or loop the animation. It can also save and load fly-over definitions to XML files and vector layers.
USAGE: Use this class to record a camera sequence and play it back in a 3D viewer.
flyOver = TGIS_3DFlyOver() flyOver.Viewer = viewer flyOver.GrabCamera() flyOver.PreparePath() flyOver.Start()
CONSTRAINTS: A valid 3D viewer or viewer window must be attached before camera capture, path movement, or playback can work. Path playback depends on previously recorded or loaded cameras, and prepared path data should be refreshed after camera list changes.
