Write SML scripts to create animated 2D and 3D "flyby" movies. You choose an elevation surface, drape layers, flight path, viewpoint, and orientation. These sample scripts show how SML gives you all the functions you need to create customized animated visualizations.

Orbit - Spiral Path. generation from 3D display using spiral orbit path. Both 2D and 3D views are copied into each movie frame. View center is fixed at center of group. Viewer position is computed from size of group. Two complete orbits are made. The first starts beyond the edge of group and spirals inward and downward; the second spirals outward and upward. Script uses an input DEM for the surface layer, an input raster drape layer, and an input vector drape layer.		ORBITSP.sml orbitsp.avi (90 Mb) orbitsp.jpg
Constant Altitude generation from 3D display using 2D vector objects to derive viewer position (flight) path and path of view center. Both 2D and 3D views are copied into each movie frame. Current viewer position and view center positions are shown in each 2D frame. Script uses input DEM for surface, an input raster drape layer, and two input vector objects, each with a single line, one defining the ground trace of the viewer position and the other defining the ground trace of the view center. Computes constant-altitude flight path a set height above the highest surface elevation beneath the flight path. View center moves on the surface.		PATHcALT.sml pathcalt.avi (58 Mb) pathcalt.jpg
Constant Height #1 generation from 3D display using 2D vector objects to derive viewer position (flight) path and path of view center. Both 2D and 3D views are copied into each movie frame. Current viewer position and view center positions are shown in each 2D frame. Script uses input DEM for surface, an input raster drape layer, and two input vector objects, each with a single line, one defining the ground trace of the viewer position and the other defining the ground trace of the view center. Computes flight path at constant height above the surface. View center moves on the surface. Both paths are partitioned into equal segments to set positions for capturing frames (to produce smoother motion). Input flight line and center line vector objects are shown in the overhead (2D) view but hidden in the 3D view.		PATHcHT1.sml pathcht1.avi (52 Mb) pathcht1.jpg
Constant Height #2: generation from 3D display using 2D vector objects to derive viewer position (flight) path and path of view center. Both 2D and 3D views are copied into each movie frame. Current viewer position and view center positions are shown in each 2D frame. Script uses input DEM for surface, an input raster drape layer, and two input vector objects, each with a single line, one defining the ground trace of the viewer position and the other defining the ground trace of the view center. Computes flight path at constant height above the surface. View center moves on the surface. Both paths are partitioned into equal segments to set positions for capturing frames (to produce smoother motion). Flight path and view center path are marked in frame by "trails" of circle symbols behind current positions.		PATHcHT2.sml pathcht2.avi (51 Mb) pathcht2.jpg
Pan: generation from 3D display with viewer position fixed and view point (view center) rotating around the viewer to produce a panning view. Both 2D and 3D views are copied into each movie frame. Current viewer position and view center positions are shown by symbols in each 2D frame.		PAN1.sml pan.mpg (1.8 Mb) pan.jpg
Viewshed: generation from 2D view showing a series of viewsheds computed from points derived by moving along a 2D path vector.		VSHEDMOV.sml vshedmov.avi (33 Mb) vshedmov.jpg
