Description This function queries a source node and returns a boolean indicating whether the ray direction specification is of the type, "M Squared Laser Beam".
Syntax flag = IsSourceDirM2Laser( srcNode )
Parameters flag (Boolean) Returned boolean flag indicating whether the source has ray directions type "M Squared Laser Beam". Returns False if ray directions are not of this type.
srcNode As Long Node number of the source whose ray directions type is being queried.
Example The following example queries a source for its ray directions type and then gets, modifies and resets the M2 Laser Beam specification.
Sub Main
Dim srcNode As Long srcNode = FindFullName( "Optical Sources.Source 1" )
Dim tM2 As T_SOURCEDIRM2LASER InitSourceDirM2Laser( tM2 ) If IsSourceDirM2Laser( srcNode ) Then GetSourceDirM2Laser( srcNode, tM2 ) tM2.M2x = 2.1 tM2.M2y = 2.1 SetSourceDirM2Laser( srcNode, tM2 ) End If
End Sub
