*SetOrientation() - marker pair angles orientation

Uses the angles orientation method to set the orientation of a marker pair.

Syntax

*SetOrientation(frame, LEFT|RIGHT, ANGLES, 
                                             ref_marker, 
                                             ang_1, 
                                             ang_2, 
                                             ang_3)

Arguments

frame: The variable name of an existing marker pair.; Data type: MarkerPair
LEFT RIGHT: See Comments.
ANGLES: This argument specifies the Euler angles (body fixed 3-1-3) method of orienting the marker pair.
ref_marker: The variable name of the marker with respect to which the Euler angles are given.; Data type: Marker
ang_1: The first of the three rotations about the Z axis of the original marker.; Data type: real
ang_2: The second rotation about the new X axis of the marker.; Data type: real
ang_3: The third rotation about the new Z axis of the marker.; Data type: real

Example

*SetOrientation(marker1, LEFT, ANGLES, , 30, 40, 50)

Context

*BeginMdl()

*DefineAnalysis()

*DefineSystem()

Comments

The Euler angles are used to orient the frame with respect to ref_marker. All angles must be given in degrees.

If the *SetOrientation() statement has no value for ref_marker, frame is oriented with respect to the global marker.

If no *SetOrientation() statement appears in the model, frame has the same orientation as the global marker.

Using the LEFT and RIGHT arguments can produce three results:

LEFT: The left marker is oriented as specified and the right marker orientation is made symmetric to the left marker.
RIGHT: The right marker is oriented as specified and the left marker orientation is made symmetric to the right marker.
Neither: The marker pair is asymmetric; attributes are assigned to the left and the right markers individually.
