Plot trajectories in trackingGlobeViewer


plotTrajectory(viewer,trajectories) plots trajectories on the tracking globe viewer.


plotTrajectory(___,Name,Value) specifies options using one or more name-value pair arguments. For example, plotTrajectory(viewer,trajectories,Color=[1 0 0]) specifies the color of the plotted trajectory as the RGB triplet [1 0 0].

Create a tracking globe viewer and specify its reference location and camera view.

refloc = [1 -5 50];
viewer = trackingGlobeViewer(ReferenceLocation=refloc);
campos(viewer,refloc + [-0.02 0 1000]);
camorient(viewer,[10 -15 0]);

Create three trajectories.

  • The first trajectory is a waypoint trajectory.

  • The second trajectory is also a waypoint trajectory, but its reference frame is specified as an ENU frame instead of the default NED frame.

  • The third trajectory is a geoTrajectory, which specifies waypoints in geodetic coordinates.

traj1 = waypointTrajectory([0 0 -400; 100 0 -400; 0 100 -400],[0 200 400]); 
traj2 = waypointTrajectory([0 0 400; 100 0 400; 0 100 400],[0 200 400],ReferenceFrame="ENU");
traj3 = geoTrajectory([1 -5 0; 1.001 -5 0; 1.002 -5 100],[0 3600 7200]);

Plot the three trajectories one by one.

plotTrajectory(viewer,traj1,Color=[1 0 0]);
plotTrajectory(viewer,traj2,Color=[0 1 0]);
plotTrajectory(viewer,traj3,Color=[0 0 1]);

Take a snapshot and show the results.


Input Arguments

collapse all

Tracking globe viewer, specified as a trackingGlobeViewer object.1

Target trajectories, specified as a waypointTrajectory object, a geoTrajectory object, or a cell array of waypointTrajectory objects or geoTrajectory objects. When specified as a cell array, trajectories can contain both waypointTrajectory objects and geoTrajectory objects. The reference frame used to plot the waypointTrajectory object is the local NED or ENU frame with its origin specified by the ReferenceLocation property of the viewer.

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: plotTrajectory(viewer,trajectories,Color=[1 0 0])

Width of the trajectory line, specified as a positive value in points, where 1 point = 1/72 of an inch. The line width cannot be thinner than the width of a pixel. If you set the line width to a value that is less than the width of a pixel on your system, the line displays as one pixel wide.

Color of trajectories, specified as one of these options:

  • A 1-by-3 RGB triplet — Plot all the trajectories with the same color.

  • An N-by-3 matrix of RGB triplets — Plot each trajectory in a different color, where N is the number of trajectories.
