IAgMtoAnalysisVisibility Interface

Example

Which tracks of the specified subset of tracks are visible from the other STK Object at the specified time?

[C#]

IAgMtoAnalysisVisibility mtoVisibility = mto.Analysis.Visibility;
mtoVisibility.UseTerrain = false; // Set to true to use terrain instead of line of sight.
mtoVisibility.Entirety = AgEMtoEntirety.eMtoEntiretyPartial; // Only applies if MTO is static (i.e. non time dependent).

Array tracksOfInterest = new object[]
                         {
                             1, 2, 7
                         };

mtoVisibility.StkObjectPath = "Satellite/J2Satellite";

// ComputeTracks expects as the second parameter a one dimensional array of mto track ids
// ComputeTracks returns a two dimensional array whose values are track id and visiblity
Array trackVisibilityArray = mtoVisibility.ComputeTracks(AgEMtoVisibilityMode.eVisibilityModeEach, ref tracksOfInterest, "1 Jan 2012 12:05:00.000");

// Output results
Console.WriteLine("ComputeTracks:");
for (int i = 0; i < trackVisibilityArray.GetLength(0); ++i)
{
    Console.WriteLine("   Track {0} visibility: {1}",
        Convert.ToInt32(trackVisibilityArray.GetValue(i, 0)),
        Convert.ToInt32(trackVisibilityArray.GetValue(i, 1)));
}

Which tracks of the specified subset of tracks are visible from the other STK Object at the specified time?

[Visual Basic .NET]

Dim trackVisibilityArray As Array = mtoVisibility.ComputeTracks(AgEMtoVisibilityMode.eVisibilityModeEach, tracksOfInterest, "1 Jan 2012 12:05:00.000")

' Output results
