Description

Returns an array of track ids with a bool value indicating if it's visible to the specified object.

Syntax

[Visual Basic .NET]
Public Function ComputeAllTracks( _ ByVal Mode As AgEMtoVisibilityMode, _ ByVal Time As System.Object _ ) As System.Array

[Visual Basic .NET]

Public Function ComputeAllTracks( _
   ByVal Mode As AgEMtoVisibilityMode, _
   ByVal Time As System.Object _
) As System.Array

[C#]
public System.Array ComputeAllTracks( AgEMtoVisibilityMode Mode, System.Object Time );

[Managed C++]
public: System::Array ComputeAllTracks( AgEMtoVisibilityMode Mode, VARIANT Time );

[Java]
public Object[] computeAllTracks( AgEMtoVisibilityMode Mode, Variant Time );

[Unmanaged C++]
public: HRESULT ComputeAllTracks( AgEMtoVisibilityMode Mode, VARIANT Time, SAFEARRAY ** Array );

[Unmanaged C++]

public: HRESULT ComputeAllTracks(
   AgEMtoVisibilityMode Mode, 
   VARIANT Time, 
   SAFEARRAY ** Array
);

Parameters

Mode

Member	Value	Description
eVisibilityModeEach	2	Returns the Track_id and 1 or 0 for every track; where 1 indicates the track is visible and 0 indicates it is not.
eVisibilityModeEachVisible	3	Returns the Track_id and 1 only for those tracks having visibility. If all objects are invisible then the message 'No Visibility' is returned.
eVisibilityModeEachNotVisible	4	Returns the Track_id and 0 for those tracks not having visibility. If all objects are visible then the message 'Complete Visibility' is returned.

Time

Example

Determine which tracks are visible from the other STK Object at the specified time
