Vector

A <Vector>-element defines a 3d vector in coordinates of the laboratory global system or in coordinates of a given local coordinate system. The element creates a trajectory with the name of the element and the type of a 3d vector of double values.

Attributes

Attribute	Description	Required
name	name of the element	Yes
localPoint	Instead of defining the point by coordinates in the laborytory global system, it is possible to define the point by arbitrary local coordinates. The global coordinates of the point are then calculated by transforming with the given coordinate system. Note: This attribute needs the use of the attribute coordinateSystem.	No
coordinateSystem	Name of the coordinate system element which is used in two cases: 1. If the point is defined in local coordinates with the attribut "localPoint" it defines the corresponding coordinate system. 2. If calibration is used, than for static trial which is defined by switches given with the attributes calibrateIncludes/calibrateExcludes the point is transformed in local coordinates of the coordinate system which is given with this element. For all other trials the local coordinates are back transformed to the global coordinates using the current value of the coordinate system defined by this attribute.	No
expr	Mathematical formula which defnines the point. Note: Typically this attribut is not used. The formula is given as elements content instead.	No
x	These attributes allows an alternative definition of the point by seperate mathematical formulas for each of the three components.	No

average	Additional calculation of the trial average. The value is saved as a parameter with the name of the element and "Average" as a suffix: <name of the element>Average

Notes

Der Parameter <name>Local wird erzeugt, wenn mit einer Kalibration gearbeitet wird. Er enthält einen gemittelten Vektor des Kalibrationstrials in lokalen Koordinaten des angegebenen Koordinatensystems.

Examples

<Vector name="A"
        coordinateSystem="Thorax"
        calibrateIncludes="static">B+C</Vector>

In the calibration trial defined by the switch "static" A is calculated as B+C in coordinates of the global laboratory system. The absolute coordinates are transformed in the given local coordinate system "Thorax". In all of the following trials A is calculated by the fixed local coordinates by transforming to global coordinates by the current attitude of the "Thorax" coordinate system.
