These images are subsequently bundled together into one file. To design a smooth and effective ground path, specify a rounded and continuous line within the extent of the surface model data. The ground path can be specified as a digitized line or as a circle. When the ground flight path is ready, it will be automatically splined to avoid abrupt changes in direction. While the ground flight path is designed on top of the displayed surface, the vertical component may be added using a diagram showing a cross-section of the terrain specified by the ground flight path and a line that represents the flight.
Several options control the movie's final form.
One of four image formats as well as standard small, standard large, or custom frame sizes can be specified for output. The output MPEG file name and entire header page can be displayed at the beginning of the movie as a movie title. The process of creating movie snapshots is time-intensive and dependent on the speed of your machine and the number of frames. Rendering a large data set can be speeded significantly by reducing the size of the image to be draped. To avoid seeing the edge of the data, which can occur when flying at high altitudes, diminish the edge by introducing the haze effect.
