Definition of a camera path
The camera path defines the flight path of the camera. It is created from a line string element digitized in the design file. To set the height of the camera path relative to the ground, the Mouse Point Adjustment tool from TerraScan or the View elevation tool from TerraModeler can be utilized. Additionally, settings for line digitization in MicroStation are useful to create a smooth camera path.
To define a camera path:
1. Load laser points of the ground into TerraScan.
1. Create a surface model with TerraModeler.
2. Select Mouse Point Adjustment tool from the Drawing tools in TerraScan.
2. Select View elevation tool from the Draw using Surface tools in TerraModeler.
3. In the Mouse Point Adjustment dialog, switch on Adjust elevation and set a value for Dz. The value defines the height above the laser points for each mouse click. Select a laser point class in the Class field.
3. In the View elevation dialog, switch on Points on surface and set a value for Dz. The value defines the height above the surface for each mouse click. Select a surface in the Surface field.
4. Select Place SmartLine tool in MicroStation. Select Rounded in the Vertex Type field, define a Rounding Radius, and switch on Join Elements.
5. Digitize a line string. The height above ground and the rounding radius settings can be changed during the digitization process. The final 3D line string can be checked by rotating the view.
6. Select the line string using Selection tool in MicroStation.
7. Select Create Flythru Movie tool from the Render tools in TerraPhoto.
This defines the line string as camera path and opens the Create Flythru Movie dialog.
3D line strings from other sources may be used as camera path as well, for example, trajectories that are drawn into the design file.
