3D Graphics Properties for STK Objects - Trajectory

Use to control the display of missile and launch vehicle trajectories.

Leading/Trailing

Inherit From 2D Graphics. If selected, Trajectory properties set for 2-D Graphics properties are used in the 3D graphics window. If not selected, trajectory display parameters for the 3D graphics window are used.

Ground Track or Trajectory

Lead Type. Defines the display of the leading portion of a vehicle's tracks. (The leading portion begins at the vehicle's present position and moves forward half the span of its ephemeris.)

Trail Type. Defines the display of the trailing portion of vehicle's track. (The trailing portion begins at the vehicle's present position and moves backward half the span of the vehicle's ephemeris.)

Values for Lead Type or Trail Type are:

  • Time. Specifies the amount of time (in seconds) that the leading or trailing portion is displayed.
  • Percent. Indicates the percentage of the leading portion or trailing portion that is displayed.
  • Quarter. Displays one quarter of the leading or trailing portion.
  • Half. Displays one half of the leading or trailing portion.
  • Full. Displays the entire leading or trailing portion.
  • All. Displays the track spanning the entire vehicle ephemeris.
  • None. Does not display the leading or trailing portion.
  • Current Interval. Display the leading or trailing portion of the vehicle's track for the current animation time interval.
  • Same As Lead option. Uses the Lead Type value for Trail Type.

Tick Marks

Defines the display of tick marks representing milestones at specified intervals along a vehicle's ground and/or trajectory in the 3D graphics window.

Ground Track or Trajectory

Show. If selected, displays tick marks.

Marker Type. Displays as either a line or point.

Point Size. The size of the point representing each tick mark.

Line Width. The width of the line representing each tick mark.

Tick Width. Indicates the actual distance that the tick extends across the ground track or trajectory

Tick Style. Disposes the tick marks in a radial or cross-track direction.

Time Between Marks. Indicates the time elapsed between each milestone indicated by a tick mark along the vehicle's path. This value applies to all tick marks showing in the 3D graphics window.
